　本実施形態は、電力需要者の電力消費属性と電力供給種別で定められている電力コスト属性とシミュレーション期間を取得し、複数の電力供給種別毎に、需要者の電力消費属性と電力供給種別で定められている電力コスト属性とに応じてシミュレーション期間で時系列に電力供給種別ごとの電力コストをシミュレーションするための演算式である電力コストシミュレーション演算式を保持し、取得した電力消費属性と保持されている電力コストシミュレーション演算式とに基づいて複数の電力供給種別の中で最も電力コストが低額となる電力供給種別をシミュレーション期間で時系列に選択するように構成された電力コストシミュレーション装置を提供する。 In the present embodiment, the power consumption attribute of the power consumer and the power cost attribute defined in the power supply type and the simulation period are acquired, and the power consumption attribute and the power supply type of the user are acquired for each of the plurality of power supply types. A power cost simulation calculation formula, which is a calculation formula for simulating the power cost for each power supply type in a time series during a simulation period according to the defined power cost attribute, is held, and the acquired power consumption attribute is held. A power cost simulation apparatus configured to select a power supply type having the lowest power cost among a plurality of power supply types in time series during a simulation period based on the power cost simulation calculation formula ..
図１６は、本実施形態の全体像を示す図である。一例として、電力コストシミュレーション装置は、太平洋電力、東海電力、日本電力、大和電力の電力供給会社４社からそれぞれ「電力コスト属性」を取得し、取得したＡＢＣコーヒーチェーンの「電力消費属性」と、取得した「シミュレーション期間」とを用いて、「電力コストシミュレーション演算式」に基づいて「最も電力コストが低額となる電力供給種別のシミュレーション期間内の選択結果」を演算するという具合である。 FIG. 16 is a diagram showing an overall image of this embodiment. As an example, the power cost simulation device acquires “power cost attributes” from four power supply companies, Pacific Power, Tokai Power, Japan Power, and Yamato Power, respectively, and acquires the “power consumption attributes” of the ABC coffee chain, Using the acquired “simulation period”, the “selection result within the simulation period of the power supply type with the lowest power cost” is calculated based on the “power cost simulation calculation formula”.
「電力供給種別」とは、電気事業者又は／及び個々の電気事業者が提供する電力供給サービスを言う。電気事業者とは、「小売電気事業者、一般送配電事業者、送電事業者、特定送配電事業者及び発電事業者」を言い、これらの組合せも電力供給種別に含まれてもよい。例えば、売電事業者と送電事業者の組合せなどである。２０１５年に「平成二十七年六月二十四日法律第四十七号」によって電気事業法の一部が改正され、２０１６年４月1日からの電力の小売り全面自由化にあわせて、改正された電気事業法が同日施行されたが、この改正前の旧来の名称で特定されていた電気事業者である「一般電気事業者、卸電気事業者、特定電気事業者及び特定規模電気事業者」が日本国では該当する。特別高圧・高圧受電による契約電力５０ｋＷ以上の需要家へ、一般電気事業者が管理する送電線を通じて小売りを行う事業者である「新電力」と呼ばれるようになった事業者も含まれる。
　図１９は、多く存在する電力供給会社のうち、選択肢となる「利用可能電力供給種別」の選択の一例を示す図である。候補としては「太平洋電力」「東海電力」「日本電力」「大和電力」「奈良電力」「沖縄電力」があり、「ＡＢＣコーヒーチェーン」が利用可能な利用可能電力供給種別としては、「太平洋電力」「東海電力」「日本電力」「大和電力」が選択されている。後述する選択部での「最も電力コストが低額となる電力供給種別」は、この選択されている電力供給種別の範囲で行われることとなる。
以下の図を用いた説明における具体例では、仮想の企業として、電力供給者である「太平洋電力」「東海電力」「日本電力」「大和電力」、電力需要者として「ＡＢＣコーヒーチェーン」を例に説明していく。 “Power supply type” means an electric power supply service provided by an electric power company or/and an individual electric power company. The electric power company means a “retail electric power company, a general power transmission and distribution company, a power transmission company, a specific power transmission and distribution company, and a power generation company”, and a combination of these may be included in the power supply type. For example, a combination of a power selling company and a power transmitting company. In 2015, a part of the Electricity Business Law was amended by "June 24, 1995, Law No. 47", in line with the full deregulation of electricity retailing from April 1, 2016. , The revised Electricity Business Law came into effect on the same day, but the electric utilities that were identified by the old name before this revision are "General Electricity Utility, Wholesale Electricity Utility, Specified Electricity Utility and Specified Scale Electricity "Business operator" is applicable in Japan. Included are companies that have come to be called “new power”, which is a business that retails to customers with contract power of 50 kW or more by extra high voltage/high voltage power reception through a transmission line managed by a general electric power company.
FIG. 19 is a diagram illustrating an example of selection of “available power supply type”, which is an option, among many power supply companies. Candidates include "Taiwan Electric Power", "Tokai Electric Power", "Japan Electric Power", "Yamato Electric Power", "Nara Electric Power", "Okinawa Electric Power", and the available power supply type that can be used by "ABC Coffee Chain" is "Pacific Electric Power". "Tokai Electric Power", "Japan Electric Power", and "Daiwa Electric Power" are selected. The "power supply type with the lowest power cost" in the selection unit described below is performed within the range of the selected power supply type.
In the concrete example in the explanation using the following figures, as an imaginary company, "Pacific Electric Power", "Tokai Electric Power", "Japan Electric Power", "Daiwa Electric Power" are electric power suppliers, and "ABC Coffee Chain" is an electric power consumer. I will explain to you.
以下、本実施形態における電力コストシミュレーション装置について、機能的構成、ハードウェア構成及び処理の流れについて、順に説明する。 Hereinafter, the functional configuration, the hardware configuration, and the flow of processing of the power cost simulation device according to the present embodiment will be sequentially described.
＜機能的構成＞
図１は、本実施形態における電力コストシミュレーション装置の機能的構成を示す図である。本実施形態における電力コストシミュレーション装置は、電力消費属性取得部（０１０１）と電力コスト属性取得部（０１０２）とシミュレーション期間取得部（０１０３）と電力コストシミュレーション演算式保持部（０１０４）と選択部（０１０５）を有する。以下、機能的構成については、具体的に各機能の内容につき説明する。 <Functional configuration>
FIG. 1 is a diagram showing a functional configuration of a power cost simulation apparatus according to this embodiment. The power cost simulation device according to the present embodiment includes a power consumption attribute acquisition unit (0101), a power cost attribute acquisition unit (0102), a simulation period acquisition unit (0103), a power cost simulation arithmetic expression holding unit (0104), and a selection unit ( 0105). Hereinafter, regarding the functional configuration, the content of each function will be specifically described.
「電力消費属性取得部」とは、電力の需要者の電力消費属性を取得する機能を有する。「電力消費属性」とは、時系列での電力消費のパターンを示すものである。時系列とは、例えば、年、月、週などの消費パターンが挙げられる。なお、「需要者」は、実在する特定の需要者であってもよいし、想定する業界の代表的かつ仮想的な需要者であてもよいし、業界自体もとくに意識しない仮想的な需要者であってもよい。つまり需要者とは、電力の消費者である。
電力消費属性取得部は、あらかじめ準備されている電力消費属性の複数のパターンから選択されてもよいし、あらかじめ準備されている電力消費属性のひながたであって、空欄を穴埋めすることによって電力消費属性を取得できるようなものであってもよい。あるいは、この穴埋め式（テキストの場合もあり。）を最初に選択させて、その後穴埋めをするようにして電力消費属性を取得するように構成してもよい。穴埋めはプルダウンメニューの選択によって行われるように構成してもよい。 The “power consumption attribute acquisition unit” has a function of acquiring the power consumption attribute of a power consumer. The “power consumption attribute” indicates a power consumption pattern in time series. Examples of the time series include consumption patterns such as year, month, and week. The "consumer" may be an actual specific consumer, a representative virtual consumer of the assumed industry, or a virtual consumer not even aware of the industry itself. May be That is, a consumer is a consumer of electricity.
The power consumption attribute acquisition unit may be selected from a plurality of patterns of power consumption attributes that are prepared in advance, or the power consumption attributes that are prepared in advance and are filled with blanks. May be obtained. Alternatively, the power consumption attribute may be obtained by first selecting this fill-in-the-blanks expression (which may be text) and then filling in the blanks. The filling may be performed by selecting a pull-down menu.
図２０は、電力消費属性の一例を示す図である。電力消費属性とは、特定の電力需要者の電力消費性向を示す情報である。例えば電力需要者の過去１年ないし過去５年の電力消費実績などから導き出すことができる。あるいは電力消費性向が近似していると仮定できる複数の電力需要者から構成されるグループの過去の電力消費実績に基づいて導き出すことができる。あるいは、実績によるよりは、本装置の設計者、管理者の過去の経験に基づいて仮想の電力需要者であればどのような電力消費性向を示すと考えられるかという仮定に基づいて設計される電力消費性向である。この仮想の電力需要者は、その電力需要者が属する産業分類（例えば日本標準産業分、設計者が適宜設計した産業分類）や業種分類（GICS業種分類、設計者が適宜設計した業種分類）と、その電力需要者の事業規模などに応じてあらかじめ準備されるものであってもよい。なお、電力消費属性は後述するシミュレーション期間に適用される電力消費属性である。つまり、電力消費属性は後述するシミュレーション期間を時間軸とした関数として得られる値となる。
　例えば、「最大消費ピーク時間帯（デマンド期間）」「（平均）使用電力量（デマンド期間別）」「最大使用電力（デマンド期間別）」「契約電力供給種別」「消費電力変化傾向（増加率、減少率）」「電力需要者の属する産業分類」「企業規模を示す情報（年間売上、従業員数、上場企業の場合には時価総額）」「電力を消費する機器別の電力消費割合」「電力消費地（地域、住所）」「電力需要者の節電履歴（節電予想）」などが挙げられる。 FIG. 20 is a diagram illustrating an example of the power consumption attribute. The power consumption attribute is information indicating the power consumption tendency of a specific power consumer. For example, it can be derived from the past one year to the past five years of electric power consumption of the electric power consumer. Alternatively, it can be derived based on the past power consumption record of a group composed of a plurality of power consumers who can be assumed to have similar power consumption propensities. Alternatively, rather than actual results, it is designed based on the assumption that what kind of power consumption tendency a virtual electric power consumer is likely to exhibit is based on the past experience of the designer and administrator of this device. It is prone to power consumption. This virtual electric power consumer has an industrial classification (for example, Japanese standard industry, an industrial classification designed by the designer) and an industrial classification (GICS industrial classification, an industrial classification designed by the designer) to which the electric power consumer belongs. Alternatively, it may be prepared in advance according to the business scale of the power consumer. The power consumption attribute is a power consumption attribute applied during the simulation period described later. That is, the power consumption attribute is a value obtained as a function whose time axis is the simulation period described later.
For example, "maximum peak consumption time zone (demand period)""(average) power consumption (by demand period)""maximum power consumption (by demand period)""contract power supply type""power consumption change tendency (increase rate , Decrease rate) "Industry classification to which power consumers belong""Information indicating company size (annual sales, number of employees, market capitalization in the case of listed companies)""Power consumption ratio by device that consumes power"" Examples include power consumption areas (regions and addresses), "electricity consumers' electricity saving history (electricity saving forecast)", and the like.
これらの電力消費属性の入力については、予め候補を用意しておいてプルダウン形式にすることが考えられる。 For inputting these power consumption attributes, it is conceivable to prepare a candidate in advance and use a pull-down format.
図１８は、電力消費属性をプルダウン形式にて入力する場合の画面の一例を示す図である。対象である電力需要者である社名が「ＡＢＣコーヒーチェーン」と入力され、その上で対象期間である「　　月　　日～　　月　　日」入力できるようになっている。その上で、上記図１７で挙げた項目が選択できるようになっており、特定の項目を選択した上でプルダウンで選択することにより、自動的に入力を完了することができる。このようにすることにより、入力内容が無数に広がることを防ぐことができる。 FIG. 18 is a diagram illustrating an example of a screen when the power consumption attribute is input in the pull-down format. The company name of the target power consumer is entered as "ABC coffee chain", and then the target period "month day to month day" can be entered. In addition, the items listed in FIG. 17 can be selected. By selecting a specific item and then selecting it from the pull-down menu, the input can be completed automatically. By doing so, it is possible to prevent the input contents from spreading innumerably.
さらに、電力消費属性取得部は、シミュレーション期間における単位時間長単位での基本となる電力消費属性を構成する設備稼働量である基本設備稼働量を保持する基本設備稼働量保持手段と、シミュレーション期間における単位時間長単位での試験的となる設備稼働量である試験的設備稼働量を取得する試験的設備稼働量取得手段と、試験的設備稼働量を含む電力消費属性を生成する試験的電力消費属性生成手段とを有していても良い。この場合、前記単位時間長は、正時からの３０分単位、正時からの３０分単位の自然数倍、正時からの２４時間単位、のいずれか一以上の単位時間長であっても良い。さらに、試験的設備稼働量取得手段は、ある単位時間長の設備稼働量と、他の単位時間長の設備稼働量とを入れ替える入替器を有していても良い。
試験的設備稼働量は、保持されている基本設備稼働量を編集することによって得られるように構成することが好ましい。基本的設備稼働量をどの程度変化させると、どのような電力供給種別の選択が有利であるかが選択部の選択結果から得られるという効果がある。さらに、この選択結果に基づいて電力コストのシミュレーションも可能であり、基本設備稼働量をどう変化させると、コストがどのように変化するかを知ることができる。さらに一の基本的設備稼働量を出発として、複数の試験的設備稼働量を取得し、これらのそれぞれについて選択部での選択結果を比較したり、コストのシミュレーション結果を比較することで、設備の仮想的な稼働計画での差異を見ることができる。さらにこれに重ねて、シミュレーション期間の同一期間で異なる複数種の電力供給種別をそれぞれ選んだ結果も比較できるようになる。なお、電力コスト属性には電力のコストの他に例えばＣＯ２の排出コストや、炭素税額が含まれるように構成してもよい。炭素税は、電力供給者に課される場合には電力コストに一般に含まれるが、炭素税の部分を明示的に抜き出して示すことによって、社会的責任投資のバロメーターとして意識するための指標とすることもできる。 Further, the power consumption attribute acquisition unit, a basic equipment operating amount holding means for holding the basic equipment operating amount that is the equipment operating amount that constitutes the basic power consumption attribute in the unit time length unit in the simulation period, and in the simulation period A test facility operation amount acquisition means for acquiring a test facility operation amount, which is a test facility operation amount in a unit of time unit, and a test power consumption attribute for generating a power consumption attribute including the test facility operation amount. It may have a generation means. In this case, the unit time length may be at least one of 30 minutes from the hour, a natural number multiple of 30 minutes from the hour, and 24 hours from the hour. good. Further, the trial facility operating amount acquisition means may include a replacement device that exchanges the facility operating amount of a certain unit time length with the facility operating amount of another unit time length.
The trial facility operating amount is preferably configured to be obtained by editing the held basic facility operating amount. There is an effect that how much the basic equipment operation amount is changed and what kind of power supply type is advantageous to select can be obtained from the selection result of the selection unit. Further, it is possible to simulate the electric power cost based on the selection result, and it is possible to know how the cost changes when the basic equipment operating amount is changed. Furthermore, starting from one basic equipment operation amount, multiple test equipment operation amounts are acquired, and the selection results in the selection unit for each of these are compared, or the simulation results of costs are compared to determine the equipment You can see the difference in the virtual operation plan. Furthermore, it becomes possible to compare the results of selecting different power supply types in the same period of the simulation period. The power cost attribute may be configured to include, for example, CO2 emission cost and carbon tax amount in addition to the power cost. The carbon tax is generally included in the electricity cost when it is imposed on the electricity supplier, but it is used as an indicator for recognizing it as a barometer of socially responsible investment by explicitly showing the portion of the carbon tax. You can also
「電力コスト属性取得部」とは、電力供給種別ごとの電力コスト属性を取得する機能を有する。「電力コスト属性」とは、いわゆる電力供給価格に関する属性であり、電力需要者に対してどのような条件、どのようなルールでどのような価格を設定するのか、あるいはどのような価格を設定する傾向があるのか、を示す情報である。例えば、国全体のあるいは、特定地域（例えば東日本、西日本、沖縄、北海道、米国であれば西海岸、東海岸など）での電力供給余力がなくなった場合あるいは国全体のあるいは、特定地域での電力供給余力が多くある場合にいかなる価格を設定するのか、など、電力供給条件と、その時の電力供給価格の関係を示す情報である。電力供給条件としては、季節、月、曜日、時間帯、地域、供給量、発電コスト、電力供給価格決定方針などである。電力供給種別毎に過去の実績の平均値や、直近の実績、あるいは実績値を基準としたものでなく過去の実績に基づく推定のコスト属性などであってよい。例えば原油価格の将来予測動向、為替相場の将来予測動向などと、過去の実績値とに基づいて後述するシミュレーション期間での電力コスト属性を予測し他者であってもよい。電力コスト属性は、後述するシミュレーション期間に適用されるべきものとして取得される。また、前述のように電力コスト属性を予測する場合には、電力コスト属性予測部を備えるように構成してもよい。そして、電力コスト属性予測部は、複数の変数を所定の演算式に入力することによって電力コスト属性の予測値を演算するための電力コスト属性予測値演算ルールを保持させ、予測される、あるいは実際の変数をそのルールに入力することによって電力コスト属性が予測値として取得されるように構成することができる。電力コスト属性は前述の通りシミュレーション期間の電力コスト属性であるので、シミュレーション期間の時間軸の関数として得られる値となる。電力コスト属性は、シミュレーション期間を構成している最小の単位に対応して定められている。
　シミュレーション期間は、通常，最小の単位はデマンド期間となり複数のデマンド期間の集合で成り立つ。つまり、シミューレーション期間の始期と終期は、デマンド期間の始期であり、同じく終期はデマンド期間の終期である。従って、この場合には電力コスト属性は、デマンド期間単位で定められることとなる。
　「デマンド期間」とは、電気料金の基本料金を定めるために用いられる期間で、日本国では毎時正時（１時、２時、３時、４時、５時、６時、７時．８時、９時、１０時、１１時、１２時、１３時、１４時、１５時、１６時、１７時、１８時、１９時、２０時、２１時、２２時、２３時、２４時（０時））から３０分間が１デマンド期間であり、さらに次の正時までの３０分間が１デマンド期間となる。 The “power cost attribute acquisition unit” has a function of acquiring the power cost attribute for each power supply type. The "electric power cost attribute" is an attribute related to a so-called electric power supply price, which condition, what kind of rule and price should be set for the electric power consumer, or what price should be set. This information indicates whether there is a tendency. For example, when there is no available power supply capacity in the whole country or in a specific area (eg, East Japan, West Japan, Okinawa, Hokkaido, West Coast, East Coast in the United States, etc.), or power supply in the whole country or in a specific area This is information indicating the relationship between the power supply condition and the power supply price at that time, such as what price should be set when there is a lot of spare capacity. The power supply conditions include season, month, day of the week, time zone, region, supply amount, power generation cost, power supply price determination policy, and the like. It may be an average value of past achievements, a latest achievement, or an estimated cost attribute based on the past achievements for each power supply type, not based on the achievement value. For example, the power cost attribute in the simulation period described later may be predicted based on the future forecast trend of the crude oil price, the future forecast trend of the exchange rate, etc. and the past actual value, and may be another person. The power cost attribute is acquired as what should be applied during the simulation period described later. When predicting the power cost attribute as described above, the power cost attribute predicting unit may be provided. The power cost attribute prediction unit holds a power cost attribute predicted value calculation rule for calculating the predicted value of the power cost attribute by inputting a plurality of variables into a predetermined calculation formula, and the predicted or actual The power cost attribute can be configured to be obtained as a predicted value by inputting the variable of the above into the rule. Since the power cost attribute is the power cost attribute of the simulation period as described above, it has a value obtained as a function of the time axis of the simulation period. The power cost attribute is defined in correspondence with the smallest unit that constitutes the simulation period.
The minimum unit of the simulation period is usually the demand period, which is a set of a plurality of demand periods. That is, the start and end of the simulation period are the start of the demand period, and the end is the end of the demand period. Therefore, in this case, the power cost attribute is determined in the demand period unit.
The "demand period" is a period used to determine the basic rate of electricity rate, and in Japan, it is every hour on the hour (1:00, 2:00, 3:00, 4:00, 5:00, 6:00, 7.8). Hours, 9 o'clock, 10 o'clock, 11 o'clock, 12 o'clock, 13 o'clock, 14 o'clock, 15 o'clock, 16 o'clock, 17 o'clock, 18 o'clock, 19 o'clock, 20 o'clock, 21 o'clock, 22 o'clock, 23 o'clock, 24 o'clock ( 30 minutes from 0:00)) is one demand period, and 30 minutes until the next hour is one demand period.
図１３は、電力需要者との関係で電力供給者別の電力コスト属性の一例を示す図である。例えば、「基本料金・基本料金履歴」「電力料料金・電力料料金履歴」「燃料調整費・燃料調整費履歴」（「燃料調整費」とは、燃料費は経済情勢（為替レートや原油価格）の影響を大きく受けるために、電力会社の経営効率化の成果を明確にするため、燃料費の変動を迅速に電気料金に反映させたもの。）「単位電力当たりのコストの変動履歴（単年度実績又は複数年平均）」「為替の変動によって受ける単位電力当たりのコストの変動」「原油その他の燃料価格の変動によって受ける単位電力当たりのコストの変動」「関税率の変動によって受ける単位電力当たりのコストの変動」「仕入元の発電所からの託送料の変動によって受ける単位電力当たりのコストの変動」などが挙げられる。 FIG. 13: is a figure which shows an example of the electric power cost attribute for every electric power supplier in relation with an electric power consumer. For example, "basic charge/basic charge history", "electric charge fee/electric charge fee history", "fuel adjustment cost/fuel adjustment cost history" ("fuel adjustment cost" means the fuel cost is the economic situation (exchange rate and crude oil price). ), the change in fuel cost is promptly reflected in the electricity rate in order to clarify the results of the efficiency improvement of the electric power company.) "Cost change history per unit electricity (single (FY actual or multi-year average)" "Cost fluctuations per unit power due to exchange rate fluctuations" "Cost fluctuations per unit power due to fluctuations in crude oil and other fuel prices" "Per unit power fluctuations due to fluctuations in tariff rates" Cost fluctuations” and “cost fluctuations per unit power received due to fluctuations in the shipping charges from the power source of the supplier”.
図２２は、太平洋電力、東海電力、日本電力、大和電力の４社における具体的な電力コスト属性を示す図である。太平洋電力は、正月やお盆期の昼間の大口需要家に割安という特徴（電力コスト属性）がある。東海電力は、年間を通じて一定程度割安に電力供給しているという特徴（電力コスト属性）がある。日本電力は、基本料金は安いが、電力料料金は比較的高いという特徴（電力コスト属性）がある。大和電力は、決算月（１２月、６月）の前後で飛びぬけて安い料金という特徴（電力コスト属性）がある。このように、電力供給会社独自の電力料金プランがあり、各々の特徴を有している。例えば、日本電力の場合には、家庭や小規模会社には有利であるが、電力を大量に消費する会社には不利である。また、家庭や小規模会社であっても、季節ごとに有利（低コスト）な電力供給会社が変わるというのが実際である。 FIG. 22 is a diagram showing specific power cost attributes of four companies, Pacific Power, Tokai Power, Japan Power, and Yamato Power. Taiheiyo Electric has a feature (electricity cost attribute) that it is cheaper for large consumers during the daytime during the New Year and the Bon Festival. Tokai Electric Power has a feature (electricity cost attribute) that it supplies electricity at a relatively low price throughout the year. Japan Electric Power has a characteristic that the basic charge is low, but the power charge is relatively high (power cost attribute). Daiwa Electric Power has a feature that it is extremely cheap (electricity cost attribute) before and after the settlement month (December, June). Thus, there are power rate plans unique to power supply companies, and each has its own characteristics. For example, in the case of Nippon Electric Power, it is advantageous for homes and small companies, but disadvantageous for companies that consume large amounts of electricity. In fact, even in households and small companies, the advantageous (low-cost) power supply company changes from season to season.
「シミュレーション期間取得部」とは、後記するシミュレーションの期間であるシミュレーション期間を取得する機能を有する。シミュレーション期間は、通常，最小の単位はデマンド期間となり複数のデマンド期間の集合で成り立つ。つまり、シミューレーション期間の始期と終期は、デマンド期間の始期であり、同じく終期はデマンド期間の終期である。
　「デマンド期間」とは、電気料金の基本料金を定めるために用いられる期間で、日本国では毎時正時（１時、２時、３時、４時、５時、６時、７時．８時、９時、１０時、１１時、１２時、１３時、１４時、１５時、１６時、１７時、１８時、１９時、２０時、２１時、２２時、２３時、２４時（０時））から３０分間と、さらに次の正時までの３０分間を言う。
　「電気料金」は通常は次のようにして定められる。
「電気料金」＝「基本料金（固定課金）」+「電力量料金（従量課金）」+「再生可能エネルギー発電促進賦課金」（電気料金には消費税などの相当額が含まれる。）
「基本料金」＝「料金単価」×「契約電力（ｋＷ）」×「（１８５－力率）/１００」
「電力量料金」＝「電力量料金単価（円/ｋＷｈ）」×「使用電力量（ｋＷｈ）」±「燃料費調整額」である。ここで「燃料費調整額」は、燃料［原油・ＬＮＧ〈液化天然ガス〉・石炭］の価格変動に応じて電気料金を調整する額である。燃料費調整額は、燃料費調整単価（円/ｋＷｈ）に使用電力量（ｋＷｈ）を乗じて算出する。
　次に契約電力の決定方法を説明する。「契約電力（ｋＷ）」の決定方法は、例えば、高圧５００ｋＷ未満の電力需要者の場合、毎月の契約電力（ｋＷ）は、メーターの計量値に基づき実量制により決定される。「実量制」とは、最大需要電力計の組み込まれた電子式電力量計で、消費された３０分ごとの電力量の平均を計量し、そのうち月間で最も大きい値を最大デマンド値・最大需要電力とする。当月を含む過去１年間の各月の最大需要電力のうちで最も大きい値が契約電力となる。
　上述のように、シミュレーション期間の代表的な例では１年間であり、新たな電力供給者と電力供給契約を結ぼうとしている場合には、その想定される契約開始日から１年間とすると便利である。新たな電力供給者に乗り換えるとどの程度向こう1年間で電力コストを抑えられるか見ることができるからである。ここで想定している新たな電力供給者の代表例は、１年を通して、常にその電力需要者に対して時系列でその期間その期間ごとに最低コストで電力を供給する電力供給者（電力供給種別）を切り替えてゆくとした場合にそれと同コストで電力を供給することを約する一の電力供給者等である。つまり、現実にはできない頻繁な電力供給者（電力供給種別）の切り替えを仮想的に行うことを可能とする電力供給ビジネスモデルをサービスする電力供給者である。つまり、その電力供給者は、前述のような、硬直的な電力料金体系（「電気料金」＝「基本料金（固定課金）」+「電力量料金（従量課金）」+「再生可能エネルギー発電促進賦課金」）を採用しないのである。
　その他にも，シミュレーション期間は，分単位であっても良いし，１時間単位であっても良いし，３時間単位であっても良いし，午前・午後単位であっても良いし，日単位であっても良いし，週単位であっても良いし，月単位であっても良いし，年単位であっても良い。 The “simulation period acquisition unit” has a function of acquiring a simulation period, which is a simulation period described later. The minimum unit of the simulation period is usually the demand period, which is a set of a plurality of demand periods. That is, the start and end of the simulation period are the start of the demand period, and the end is the end of the demand period.
The "demand period" is a period used to determine the basic rate of electricity rate, and in Japan, it is every hour on the hour (1:00, 2:00, 3:00, 4:00, 5:00, 6:00, 7.8). Hours, 9 o'clock, 10 o'clock, 11 o'clock, 12 o'clock, 13 o'clock, 14 o'clock, 15 o'clock, 16 o'clock, 17 o'clock, 18 o'clock, 19 o'clock, 20 o'clock, 21 o'clock, 22 o'clock, 23 o'clock, 24 o'clock ( 30 minutes from 0:00)) to the next hour.
The "electricity charge" is usually determined as follows.
"Electricity charge" = "Basic charge (fixed charge)" + "Electricity charge (pay-as-you-go)" + "Renewable energy power generation promotion levy" (Electricity charges include consumption tax and other equivalent amounts.)
"Basic rate" = "Unit price" x "Contracted electricity (kW)" x "(185-Power factor)/100"
"Electric power charge" = "Electric power charge unit price (yen/kWh)" x "Electric power consumption (kWh)" ± "Fuel cost adjustment amount". Here, the "fuel cost adjustment amount" is an amount for adjusting the electricity price according to the price fluctuation of fuel [crude oil/LNG <liquefied natural gas>coal]. The fuel cost adjustment amount is calculated by multiplying the fuel cost adjustment unit price (yen/kWh) by the power consumption (kWh).
Next, a method for determining contracted power will be described. As for the method of determining the "contracted power (kW)", for example, in the case of a power consumer with a high voltage of less than 500 kW, the monthly contracted power (kW) is determined by the actual amount system based on the metered value. "Actual amount system" is an electronic watt-hour meter with a built-in maximum demand watt-hour meter. It measures the average of the amount of electricity consumed every 30 minutes, and the largest value in the month is the maximum demand value/maximum value. Demand power. The largest value of the maximum demand power of each month in the past year including the current month is the contract power.
As described above, a typical example of the simulation period is one year, and if you are going to enter into a power supply contract with a new power supplier, it is convenient to set it as one year from the expected contract start date. is there. This is because it will be possible to see how switching to a new electricity supplier will reduce electricity costs in the coming year. A typical example of a new power supplier assumed here is a power supplier (power supplier who always supplies power to the power consumer at a lowest cost in each time period and time period throughout the year. This is one electric power supplier who promises to supply electric power at the same cost when the type is switched. In other words, it is a power supplier that provides a power supply business model that enables virtual switching of frequent power supply (power supply type) that cannot be done in reality. In other words, the electric power supplier has a rigid electricity charge system as described above (“electricity charge” = “basic charge (fixed charge)” + “electricity charge (metered charge)” + “renewable energy power generation promotion”). The levy") is not adopted.
In addition, the simulation period may be a minute unit, an hour unit, a three hour unit, an am/pm unit, or a day unit. , Weekly, monthly, or yearly.
「電力コストシミュレーション演算式保持部」とは、複数の電力供給種別毎に、需要者の電力消費属性と電力供給種別で定められている電力コスト属性と、に応じてシミュレーション期間で時系列に電力供給種別ごとの電力コストをシミュレーションするための演算式である電力コストシミュレーション演算式を保持する機能を有する。
　代表的な「電力コストシミュレーション演算式」としては、シミューレーション期間の単位時間（例えばデマンド単位期間）ごとに、電力消費属性に含まれている電力消費量の値（例えば１０００ｋｗｈ）と、電力コスト属性に含まれている単位電力量当たりのコスト（金銭単位であっても、それ以外の単位であっても構わない。例えば１０円／１ｋｗｈ）を掛け合わせる処理（例えば１０００ｋｗｈ×（１０円／１ｋｗｈ）＝１００００円）をするための演算式となる。 The "electric power cost simulation equation holding unit" means, for each of a plurality of electric power supply types, power consumption in time series during the simulation period according to the power consumption attribute of the consumer and the electric power cost attribute determined by the electric power supply type. It has a function of holding an electric power cost simulation arithmetic expression which is an arithmetic expression for simulating the electric power cost for each supply type.
As a typical “power cost simulation arithmetic expression”, the value of the power consumption included in the power consumption attribute (for example, 1000 kwh) and the power cost for each unit time of the simulation period (for example, demand unit period) A process for multiplying the cost per unit amount of electric power included in the attribute (whether it is a monetary unit or another unit. For example, 10 yen/1 kwh) (for example, 1000 kwh×(10 yen/1 kwh) )=10000 yen).
「選択部」とは、取得した電力消費属性と、取得した電力コスト属性と、保持されている電力コストシミュレーション演算式と、に基づいて複数の電力供給種別の中で最も電力コストが低額となる電力供給種別をシミュレーション期間内で時系列に選択する機能を有する。シミュレーション期間はシーズンが１周する１年間が典型的である。電力消費パターンは、通常１年間で１サイクルするからである。
　電力供給種別の選択をする最小の期間単位は、デマンド期間である。デマンド期間は前述の通りであるので、最も頻繁には３０分間隔で電力供給種別を選択するように設計できる。ただし、これに限定されるものでなく、３０分の自然数倍の期間を電力供給種別の切り替えを行うことができる時間長として選択することができる。電力事業者の切り替えの現実のルールに合わせる必要がない点がこの装置の特徴である。また、この電力供給種別の切り替え期間は、切換期間を選択するように構成することも可能である。その場合には、選択部に切換期間選択手段を設けることが考えられる。 The “selection unit” has the lowest power cost among the plurality of power supply types based on the acquired power consumption attribute, the acquired power cost attribute, and the held power cost simulation calculation formula. It has a function to select the power supply type in time series within the simulation period. The simulation period is typically one year with one season. This is because the power consumption pattern normally makes one cycle in one year.
The minimum period unit for selecting the power supply type is the demand period. Since the demand period is as described above, it can be designed to select the power supply type most frequently at intervals of 30 minutes. However, the present invention is not limited to this, and a period of a natural number multiple of 30 minutes can be selected as the time length for which the power supply type can be switched. The feature of this device is that it is not necessary to comply with the actual rules for switching between electric power companies. Further, the switching period of the power supply type can be configured to select the switching period. In that case, it is conceivable to provide the selection unit with switching period selection means.
図２１は、特定の電力需要者の電力消費属性に基づく電力供給会社４社の月々の特定の電力需要者に対して発生する電力コスト（円／ｋｗ）の一例を示す図である。ここでは、時系列での選択期間単位を月単位とし、シミュレーション期間はシーズンが１周する１年間という例で示している。
太平洋電力は、１１月が「２３．０」、１２月が「２１．５」、１月が「２１．５」、２月が「２２．５」、３月が「２３．５」、４月が「２５．０」、５月が「２３．５」、６月が「２２．５」、７月が「２１．０」、８月が「２１．５」、９月が「２３．５」、１０月が「２５．０」である。

日本電力は、１１月が「１７．５」、１２月が「２０．５」、１月が「２３．５」、２月が「２５．０」、３月が「２２．０」、４月が「２２．５」、５月が「２０．５」、６月が「１８．５」、７月が「２１．０」、８月が「２３．０」、９月が「２２．０」、１０月が「２２．５」である。
大和電力は、１１月が「１５．０」、１２月が「２０．０」、１月が「２２．５」、２月が「２０．５」、３月が「２１．０」、４月が「２０．５」、５月が「１９．５」、６月が「１５．５」、７月が「１８．０」、８月が「２２．５」、９月が「２５．５」、１０月が「２３．５」である。
以上の電力コストを前提とすると、最も電力コストが低額となる電力供給種別は、図中の数字を囲んでいる部分である。具体的には、１１月は「１５．０」（大和電力）、１２月は「１９．０」（東海電力）、１月は「２１．５」（太平洋電力、東海電力）、２月は「２０．５」（大和電力）、３月は「１９．５」（東海電力）、４月は「１７．０」（東海電力）、５月は「１７．５」（東海電力）、６月は「１５．５」（大和電力）、７月は「１８．０」（大和電力）、８月は「２１．５」（太平洋電力）、９月は「２０．０」（東海電力）、１０月は「１９．０」（東海電力）が最も電力コストが低額となる電力供給種別である。選択部では、当該供給種別が選択される。 FIG. 21: is a figure which shows an example of the electric power cost (yen/kw) which arises with respect to the monthly specific power consumer of four power supply companies based on the power consumption attribute of a specific power consumer. Here, an example is shown in which the selection period unit in the time series is the monthly unit, and the simulation period is one year in which the season makes one round.
For Pacific Power, “23.0” in November, “21.5” in December, “21.5” in January, “22.5” in February, “23.5” in March, 4 Month is “25.0”, May is “23.5”, June is “22.5”, July is “21.0”, August is “21.5”, and September is “23. 5" and October are "25.0".
Tokai Electric Power has “17.5” in November, “19.0” in December, “21.5” in January, “25.0” in February, “19.5” in March, and 4 Month is “17.0”, May is “17.5”, June is “18.5”, July is “24.0”, August is “25.5”, and September is “20. 0" and October are "19.0".
For Nippon Electric Power, "17.5" in November, "20.5" in December, "23.5" in January, "25.0" in February, "22.0" in March, and 4 Month is “22.5”, May is “20.5”, June is “18.5”, July is “21.0”, August is “23.0”, and September is “22. 0" and October are "22.5".
Yamato Electric has “15.0” in November, “20.0” in December, “22.5” in January, “20.5” in February, “21.0” in March, and 4 Month is “20.5”, May is “19.5”, June is “15.5”, July is “18.0”, August is “22.5”, and September is “25. 5” and October are “23.5”.
Assuming the above power cost, the power supply type with the lowest power cost is the part enclosing the numbers in the figure. Specifically, “15.0” (Yamato Electric Power) in November, “19.0” (Tokai Electric Power) in December, “21.5” (Pacific Electric Power, Tokai Electric Power) in January, and February "20.5" (Yamato Electric Power), "19.5" (Tokai Electric Power) in March, "17.0" (Tokai Electric Power) in April, "17.5" (Tokai Electric Power) in May, 6 Month is "15.5" (Yamato Electric Power), July is "18.0" (Yamato Electric Power), August is "21.5" (Pacific Electric Power), September is "20.0" (Tokai Electric Power) In October, “19.0” (Tokai Electric Power) is the type of power supply with the lowest power cost. The selection unit selects the supply type.
図１４は、選択部での選択内容の一例をグラフにして示す図である。ここでも、時系列での選択期間単位を月単位とし、シミュレーション期間はシーズンが１周する１年間という例で示している。各数値の内容は図２１のとおりであるが、電力コストを縦軸にとったグラフにしてみた場合、最も下にくる電力供給種別が最も電力コストが低額となる電力供給種別なわけであるから、選択される電力供給種別は、各月における最も下にくる電力供給種別ということになる。 FIG. 14 is a graph showing an example of the contents selected by the selection unit. Also here, the selection period unit in the time series is set to the month unit, and the simulation period is shown as an example of one year in which the season makes one round. The content of each numerical value is as shown in FIG. 21, but in a graph with the power cost on the vertical axis, the lowest power supply type is the power supply type with the lowest power cost. The selected power supply type is the lowest power supply type in each month.
図１５は、ＡＢＣコーヒーチェーンが太平洋電力を利用している場合を例にとって、選択後電力供給種別との電力コストの比較をグラフにした図である。選択後電力供給種別は「最も電力コストが低額となる電力供給種別」なわけであるから、太平洋電力よりも電力コストが高額になることはない。例えば、電力供給会社４社の中で太平洋電力の電力コストが最も低額であった１月と８月は、その電力コストの電力供給種別（太平洋電力）が選択されている。他方、１月と８月を除く月については、太平洋電力以外の会社の電力コストが最も低額であったことから、当該最も低額であった電力会社の電力供給種別が選択される。そのため、その月については、太平洋電力による電力コストよりも低額となる。そのため、年間を通じてみると、ＡＢＣコーヒーチェーンにとって、大幅な電力コストのダウンにつながることがシミュレーションによって明らかになる。つまり新たな電力事業者のビジネスモデルとしてこのような料金体系を電力需要者に提示できれば今までにない低コストでの電力供給が電力需要者に対して可能となるので、電力需要者も大きなコスト削減ができその事業者を選択する動機づけとなる。 FIG. 15 is a graph showing a comparison of the power cost with the selected power supply type, taking the case where the ABC coffee chain uses Pacific power as an example. Since the selected power supply type is “the power supply type with the lowest power cost”, the power cost will not be higher than Pacific power. For example, in January and August when the power cost of the Pacific power is the lowest among the four power supply companies, the power supply type (Pacific power) of the power cost is selected. On the other hand, for the months other than January and August, the power costs of the companies other than Pacific Power were the lowest, so the power supply type of the power company that was the lowest was selected. Therefore, the electricity cost for the month will be lower than the electricity cost by Pacific Power. As a result, simulations show that the ABC coffee chain will lead to a significant reduction in electricity costs over the course of the year. In other words, if such a tariff system can be presented to electric power consumers as a business model of a new electric power company, it will be possible to supply electric power consumers with an unprecedented low cost. It is possible to reduce, and it becomes an incentive to select the business operator.
以上は実績値をコスト属性として採用した場合の選択であるが、電力消費属性と実績値を直接的に採用しない電力コスト属性とに基づいて、最も電力コストが低額になると判断される電力供給種別を選択するように構成しても良い。つまり、電力供給種別毎の過去の実績値そのものを電力コスト属性とする者ではないが、過去の実績値などに基づいて各電力供給種別毎の将来に予測される電力コスト属性を導き出し利用する場合である。具体的には、「電力消費属性」として大口需要家で季節変動が激しいのであれば、シミュレーション期間である将来に予測される「電力コスト属性」で、大口需要家に不利な電力供給種別の選択は避け、しかも季節変動の内容に鑑みて最も安くなる電力供給種別（大量に電力消費する時期に電力コストの単価が安い電力供給種別）を選択するという具合である。この場合には例えば大口需要家に有利と考えられる電力供給種別は複数存在する可能性があってもよい。そしてそのような場合には複数の中からいずれを選択するかは、発明装置を管理する者が決定してもよいし、管理者にシミュレーションを依頼する電力需要者が選択するようにしてもよいし、発明装置が乱数などを利用して任意に選択するように構成してもよい。
　また、いずれの電力供給種別を選択するかに関して選択性向が異なるシナリオを複数準備して電力需要者等にシナリオを選択させ、その選択されたシナリオに沿って電力供給種別を選択するように構成することもできる。このために電力コストシミュレーション装置には、シナリオ保持部と、シナリオ選択受付部と、シナリオによって選択部を制御するシナリオ選択制御部を備えるように構成することができる。さらに、電力コストシミュレーション装置は、複数のシナリオをすべて自動的に順次選択して選択部を制御しながら選択を実行し、実行結果を比較して最も電力コストがシミューレーション期間の全体で比較したときに最低となる結果となったシナリオによって選択された選択結果を選択部の選択結果とするように構成することもできる。そのために電力コストシミュレーション装置は、自動シナリオ実行部を有するように構成することができる。また、各種の電力供給や電力需要に関する社会的な出来事に応じて適切なシナリオを準備できるように、シナリオ構成部を設けるようにしてもよい。シナリオ構成部は予測される社会情勢に応じてシナリオに影響を与える変数を有し、実際の社会情勢に応じてその変数に値を代入することでシナリオが生成されるようにすることが好ましい。そのためにはシナリオ構成部に対して変数の値を与えるシナリオ変数取得部を電力コストシミュレーション装置に備えることが好ましい。 The above is the selection when the actual value is adopted as the cost attribute, but the power supply type determined to have the lowest power cost based on the power consumption attribute and the power cost attribute that does not directly adopt the actual value. May be configured to be selected. In other words, if the past actual value of each power supply type is not the person who uses it as the power cost attribute, but the power cost attribute predicted in the future for each power supply type is derived based on the past actual value and used. Is. Specifically, if the large-scale consumers have large seasonal fluctuations as the "power consumption attribute", the "power cost attribute" predicted in the future, which is the simulation period, is used to select the power supply type that is disadvantageous to the large-scale consumer. In addition, the power supply type that is the cheapest (the power supply type that has the lowest unit price of the power cost when a large amount of power is consumed) is selected in consideration of the contents of seasonal fluctuations. In this case, for example, there may be a plurality of power supply types that are considered to be advantageous to large-scale customers. In such a case, the person who manages the invention device may decide which one is selected from the plurality, or the power consumer who requests the manager to perform the simulation may select one. However, the invention device may be configured to arbitrarily select using a random number or the like.
In addition, it is configured to prepare a plurality of scenarios having different selectivity with respect to which power supply type is selected, allow the power consumer or the like to select the scenario, and select the power supply type according to the selected scenario. You can also For this reason, the power cost simulation apparatus can be configured to include a scenario holding unit, a scenario selection receiving unit, and a scenario selection control unit that controls the selection unit according to the scenario. Further, the power cost simulation device automatically selects a plurality of scenarios in sequence and executes the selection while controlling the selection unit, compares the execution results, and compares the most power costs in the entire simulation period. It is also possible to configure the selection result selected by the scenario having the lowest result to be the selection result of the selection unit. Therefore, the power cost simulation device can be configured to have an automatic scenario execution unit. Further, a scenario configuration unit may be provided so that an appropriate scenario can be prepared according to social events related to various types of power supply and power demand. It is preferable that the scenario configuration unit has a variable that influences the scenario according to the predicted social situation, and the scenario is generated by substituting a value for the variable according to the actual social situation. For that purpose, it is preferable that the power cost simulation apparatus is provided with a scenario variable acquisition unit that gives a value of the variable to the scenario configuration unit.
図１７は、ＡＢＣコーヒーチェーンを例にとって、電力消費属性と電力コスト属性とに基づいて、最も電力コストが低額になると判断される電力供給種別を選択する場合の一例を示す図である。ＡＢＣコーヒーチェーンは、「正月やお盆の帰省時期に顧客数が急増し、電力消費が増大する」「大口需要家である」という電力消費属性を有するとする。その場合、図２２における各社（電力供給種別）の電力コスト属性を踏まえると、大口需要家に不利である日本電力は選択から外れる。その上で、正月やお盆の期間は「太平洋電力」、通常月は「東海電力」、特に大和電力が安い月は「大和電力」という具合に選択することができる。 FIG. 17 is a diagram illustrating an example of selecting an electric power supply type that is determined to have the lowest electric power cost based on the electric power consumption attribute and the electric power cost attribute, taking the ABC coffee chain as an example. It is assumed that the ABC coffee chain has the power consumption attributes of "the number of customers will increase sharply and the power consumption will increase at the time of returning home during New Year holidays and Obon" and "being a large consumer". In that case, considering the power cost attribute of each company (power supply type) in FIG. 22, Japan Electric Power, which is disadvantageous to large-scale customers, is excluded from the selection. On top of that, you can select "Pacific power" during the New Year and Obon periods, "Tokai power" for normal months, and "Yamato power" for particularly cheap Yamato power.
＜ハードウェア構成＞
本実施形態における電力コストシミュレーション装置のハードウェア構成について、図を用いて説明する。 <Hardware configuration>
The hardware configuration of the power cost simulation apparatus according to this embodiment will be described with reference to the drawings.
図２は、本実施形態における電力コストシミュレーション装置のハードウェア構成を示す図である。　この図にあるように、コンピュータは、マザーボード上に構成される、チップセット（０２１０）、ＣＰＵ（０２０１）、不揮発性メモリ（０２０３）、メインメモリ（０２０４）、各種バス（０２０２ａ～０２０２ｅ）、ＢＩＯＳ（０２０７）各種インターフェイス（０２０５、０２０６、０２０８）、リアルタイムクロック（０２０９）等からなる。これらはオペレーティングシステムやデバイスドライバー、各種プログラムなどと協働して動作する。本発明を構成する各種プログラムや各種データはこれらのハードウエア資源を効率的に利用して各種の処理を実行するように構成されている。
＜チップセット＞
　「チップセット」は、コンピュータのマザーボードに実装され、ＣＰＵの外部バスと、メモリや周辺機器を接続する標準バスとの連絡機能、つまりブリッジ機能を集積した大規模集積回路（ＬＳＩ）のセットである。２チップセット構成を採用する場合と、１チップセット構成を採用する場合とがある。ＣＰＵやメインメモリに近い側をノースブリッジ、遠い側で比較的低速な外部Ｉ/Ｏとのインタフェースの側にサウスブリッジが設けられる。
（ノースブリッジ）
ノースブリッジには、ＣＰＵインターフェース、メモリコントローラ、グラフィックインターフェースが含まれる。従来のノースブリッジの機能のほとんどをＣＰＵに担わせてもよい。ノースブリッジは、メインメモリのメモリスロットとはメモリバスを介して接続し、グラフィックカードのグラフィックカードスロットとは、ハイスピードグラフィックバス（ＡＧＰ、ＰＣＩ　Ｅｘｐｒｅｓｓ）で接続される。
（サウスブリッジ）
サウスブリッジには、ＰＣＩインターフェイス（ＰＣＩスロット）とはＰＣＩバスを介して接続し、ＡＴＡ（ＳＡＴＡ）インターフェイス、ＵＳＢインターフェイス、ＥｔｈｅｒｎｅｔインターフェイスなどとのＩ／Ｏ機能やサウンド機能を担う。高速な動作が必要でない、あるいは不可能であるようなＰＳ/２ポート、フロッピーディスクドライブ、シリアルポート、パラレルポート、ＩＳＡバスをサポートする回路を組み込むことは、チップセット自体の高速化の足かせとなるためサウスブリッジのチップから分離させ、スーパーＩ/Ｏチップと呼ばれる別のＬＳＩに担当させることとしてもよい。ＣＰＵ（ＭＰＵ）と、周辺機器や各種制御部を繋ぐためにバスが用いられる。バスはチップセットによって連結される。メインメモリとの接続に利用されるメモリバスは、高速化を図るために、これに代えてチャネル構造を採用してもよい。バスとしてはシリアルバスかパラレルバスを採用できる。パラレルバスは、シリアルバスが1ビットずつデータを転送するのに対して、元データそのものや元データから切り出した複数ビットをひとかたまりにして、同時に複数本の通信路で伝送する。クロック信号の専用線がデータ線と平行して設け、受信側でのデータ復調の同期を行う。ＣＰＵ（チップセット）と外部デバイスをつなぐバスとしても用いられ、ＧＰＩＢ、ＩＤＥ/（パラレル）ＡＴＡ、ＳＣＳＩ、ＰＣＩなどがある。高速化に限界があるため、ＰＣＩの改良版ＰＣＩ ＥｘｐｒｅｓｓやパラレルＡＴＡの改良版シリアルＡＴＡでは、データラインはシリアルバスでもよい。
＜ＣＰＵ＞
ＣＰＵはメインメモリ上にあるプログラムと呼ばれる命令列を順に読み込んで解釈・実行することで信号からなる情報を同じくメインメモリ上に出力する。ＣＰＵはコンピュータ内での演算を行なう中心として機能する。なお、ＣＰＵは演算の中心となるＣＰＵコア部分と、その周辺部分とから構成され、ＣＰＵ内部にレジスタ、キャッシュメモリや、キャッシュメモリとＣＰＵコアとを接続する内部バス、ＤＭＡコントローラ、タイマー、ノースブリッジとの接続バスとのインターフェイスなどが含まれる。なお、ＣＰＵコアは一つのＣＰＵ（チップ）に複数備えられていてもよい。また，ＣＰＵに加えて，グラフィックインターフェイス（ＧＰＵ）若しくはＦＰＵによって，処理を行っても良い。
＜不揮発性メモリ＞
（ＨＤＤ）
ハードディスクドライブの基本構造は、磁気ディスク、磁気ヘッド、および磁気ヘッドを搭載するアームから構成される。外部インターフェイスは、SATA(過去ではATA)を採用することができる。高機能なコントローラ、例えばＳＣＳＩを用いて、ハードディスクドライブ間の通信をサポートする。例えば、ファイルを別のハードディスクドライブにコピーする時、コントローラがセクタを読み取って別のハードディスクドライブに転送して書き込むといったことができる。この時ホストCPUのメモリにはアクセスしない。したがってＣＰＵの負荷を増やさないで済む。
＜メインメモリ＞
　ＣＰＵが直接アクセスしてメインメモリ上の各種プログラムを実行する。メインメモリは揮発性のメモリでＤＲＡＭが用いられる。メインメモリ上のプログラムはプログラムの起動命令を受けて不揮発性メモリからメインメモリ上に展開される。その後もプログラム内で各種実行命令や、実行手順に従ってＣＰＵがプログラムを実行する。
＜オペレーティングシステム（ＯＳ）＞
　オペレーティングシステムはコンピュータ上の資源をアプリケーションに利用させるための管理をしたり、各種デバイスドライバを管理したり、ハードウエアであるコンピュータ自身を管理するために用いられる。小型のコンピュータではオペレーティングシステムとしてファームウエアを用いることもある。
＜ＢＩＯＳ＞
　ＢＩＯＳは、コンピュータのハードウエアを立上てオペレーティングシステムを稼働させるための手順をＣＰＵに実行させるもので、最も典型的にはコンピュータの起動命令を受けるとＣＰＵが最初に読取りに行くハードウエアである。ここには、ディスク（不揮発性メモリ）に格納されているオペレーティングシステムのアドレスが記載されており、ＣＰＵに展開されたＢＩＯＳによってオペレーティングシステムが順次メインメモリに展開されて稼働状態となる。なお、ＢＩＯＳは、バスに接続されている各種デバイスの有無をチェックするチェック機能をも有している。チェックの結果はメインメモリ上に保存され、適宜オペレーティングシステムによって利用可能な状態となる。なお、外部装置などをチェックするようにＢＩＯＳを構成してもよい。 FIG. 2 is a diagram showing a hardware configuration of the power cost simulation apparatus according to this embodiment. As shown in this figure, the computer is configured on a motherboard and includes a chip set (0210), a CPU (0201), a non-volatile memory (0203), a main memory (0204), various buses (0202a to 0202e), and a BIOS. (0207) Various interfaces (0205, 0206, 0208), real time clock (0209), etc. These operate in cooperation with the operating system, device drivers, and various programs. Various programs and various data that constitute the present invention are configured to efficiently use these hardware resources to execute various processes.
<Chipset>
A "chipset" is a set of large-scale integrated circuits (LSI) that is mounted on a motherboard of a computer and that has a function of connecting a CPU external bus and a standard bus that connects a memory and peripheral devices, that is, a bridge function. .. There are cases where the two-chip set configuration is adopted and cases where the one-chip set configuration is adopted. A north bridge is provided on the side close to the CPU and main memory, and a south bridge is provided on the side far from the interface with the relatively slow external I/O.
(Northbridge)
The north bridge includes a CPU interface, a memory controller, and a graphic interface. Most of the functions of the conventional north bridge may be assigned to the CPU. The north bridge is connected to the memory slot of the main memory via a memory bus, and is connected to the graphic card slot of the graphic card by a high speed graphic bus (AGP, PCI Express).
(South Bridge)
The south bridge is connected to a PCI interface (PCI slot) via a PCI bus, and has an I/O function and a sound function with an ATA (SATA) interface, a USB interface, an Ethernet interface, and the like. Incorporating circuits that support PS/2 ports, floppy disk drives, serial ports, parallel ports, and ISA buses that do not require or are not capable of high-speed operation is a hindrance to speeding up the chipset itself. Therefore, it may be separated from the south bridge chip and assigned to another LSI called a super I/O chip. A bus is used to connect the CPU (MPU) to peripheral devices and various control units. The buses are connected by chipsets. The memory bus used for connection with the main memory may have a channel structure instead of this in order to increase the speed. The bus can be a serial bus or a parallel bus. The parallel bus transfers data one bit at a time, whereas the serial bus transfers the original data itself or multiple bits cut out from the original data as a group and transmits them simultaneously on multiple communication paths. A dedicated line for the clock signal is provided in parallel with the data line to synchronize the data demodulation on the receiving side. It is also used as a bus that connects a CPU (chipset) and external devices, and includes GPIB, IDE/(parallel) ATA, SCSI, PCI, and the like. Since there is a limit to the speedup, in the improved PCI Express of PCI and the improved serial ATA of parallel ATA, the data line may be a serial bus.
<CPU>
The CPU sequentially reads a sequence of instructions called a program on the main memory, interprets and executes it, and outputs information consisting of signals to the main memory as well. The CPU functions as a center for performing calculations in the computer. It should be noted that the CPU is composed of a CPU core portion which is the center of calculation and a peripheral portion thereof, and has a register, a cache memory inside the CPU, an internal bus connecting the cache memory and the CPU core, a DMA controller, a timer, a north bridge. Includes interfaces to and from the connection bus. A plurality of CPU cores may be included in one CPU (chip). Further, the processing may be performed by a graphic interface (GPU) or FPU in addition to the CPU.
<Nonvolatile memory>
(HDD)
The basic structure of a hard disk drive is composed of a magnetic disk, a magnetic head, and an arm carrying the magnetic head. The external interface can adopt SATA (in the past, ATA). A high performance controller, for example SCSI, is used to support communication between hard disk drives. For example, when copying a file to another hard disk drive, the controller can read the sectors and transfer to another hard disk drive for writing. At this time, the memory of the host CPU is not accessed. Therefore, it is not necessary to increase the load on the CPU.
<Main memory>
The CPU directly accesses and executes various programs on the main memory. The main memory is a volatile memory and a DRAM is used. The program on the main memory is expanded from the non-volatile memory to the main memory in response to the program start instruction. After that, the CPU executes the program according to various execution instructions and the execution procedure in the program.
<Operating system (OS)>
The operating system is used to manage the resources on the computer for use by applications, to manage various device drivers, and to manage the computer itself, which is hardware. In a small computer, firmware may be used as an operating system.
<BIOS>
The BIOS causes the CPU to execute the procedure for booting up the computer hardware and operating the operating system, and is most typically the hardware that the CPU first reads when receiving the boot instruction of the computer. .. Here, the address of the operating system stored in the disk (nonvolatile memory) is described, and the operating system is sequentially expanded in the main memory by the BIOS expanded in the CPU to be in the operating state. Note that the BIOS also has a check function for checking the presence/absence of various devices connected to the bus.

以下、本実施形態における電力コストシミュレーション装置について、機能的構成、ハードウェア構成及び処理の流れについて、順に説明する。 Hereinafter, the functional configuration, the hardware configuration, and the flow of processing of the power cost simulation device according to the present embodiment will be sequentially described.
＜機能的構成＞
図４は、本実施形態における電力コストシミュレーション装置の機能的構成を示す図である。本実施形態における電力コストシミュレーション装置は、電力消費属性取得部（０４０１）と電力コスト属性取得部（０４０２）とシミュレーション期間取得部（０４０３）と電力コストシミュレーション演算式保持部（０４０４）と選択部（０４０５）と電力コスト演算部（０４０６）と選択後電力コストシミュレーション結果出力部（０４０７）を有する。以下、具体的に各機能の内容につき説明する。なお、電力コスト演算部と選択後電力コストシミュレーション結果出力部を除く各機能については、実施形態１と同様であるため、電力コスト演算部と選択後電力コストシミュレーション結果出力部の機能に限定して説明する。 <Functional configuration>
FIG. 4 is a diagram showing a functional configuration of the power cost simulation apparatus according to this embodiment. The power cost simulation device according to the present embodiment includes a power consumption attribute acquisition unit (0401 ), a power cost attribute acquisition unit (0402 ), a simulation period acquisition unit (0403 ), a power cost simulation formula holding unit (0404 ), and a selection unit ( 0405), a power cost calculation unit (0406), and a selected power cost simulation result output unit (0407). The contents of each function will be specifically described below. Since the respective functions except the power cost calculation unit and the selected power cost simulation result output unit are the same as those of the first embodiment, the functions are limited to the functions of the power cost calculation unit and the selected power cost simulation result output unit. explain.
「電力コスト演算部」とは、選択部での時系列に選択された電力供給種別の選択に従ってシミュレーション期間に電力を消費した場合の電力コストを演算する機能を有する。
　「電力コスト」とは、電力を消費するために支払うべき対価であって、一般的には通貨の単位で示される。ただし、金銭にのみ限られず、流通している電子マネーや流通して有価証券として価値を有するポイントなどに換算して示してもよい。例えばポイントとしては、各電力供給種別が発行するポイントなどを挙げることができる。
　さらに電力コストは電力需要者のシミュレーション期間中に電力消費属性によって予測される電力消費量に対して演算した電力消費量見合いの電力コストでもよいし、電力消費属性によって予測される電力消費量でなく、その電力消費を前提として単位電力消費量当たりの電力コストを算出してもよい。
　さらに演算される電力コストは、シミュレーション期間を複数のサブ期間に分けてサブ期間単位で算出され結果が示されるものであってもよい。また、電力コストは、電力コストを演算するために用いた電力コスト属性や、電力消費属性の代表値あるいは、一例で演算されたものであり、これらの値を変更して再シミュレーションが直ちに示されるようなダイナミック関数を有する電力コストであってもよい。つまり、電力コストのグラフなどが一旦は示されるが電力コスト属性や電力消費属性として利用された値がディスプレイなどに表示され、そのディスプレイに表示された値を電力需要者や電力コストシミュレーション装置の管理者が変更できるように構成し、変更した後に再計算ボタンなどを押下すると、新たな演算が直ちに行われグラフが動的に変化するように構成することができる。そのために演算結果自体が変数の変更を受付けるダイナミック関数であるように演算部はダイナミック関数型演算結果演算手段を有するように構成することができる。 The “power cost calculation unit” has a function of calculating the power cost when power is consumed during the simulation period according to the selection of the power supply type selected in time series by the selection unit.
The "electric power cost" is a consideration to be paid for consuming electric power, and is generally shown in a unit of currency. However, the present invention is not limited to money, and may be converted into electronic money that is in circulation or points that have value as securities that are in circulation. For example, points can be points issued by each power supply type.
Further, the electric power cost may be the electric power cost corresponding to the electric power consumption calculated for the electric power consumption predicted by the electric power consumption attribute during the simulation of the electric power consumer, or the electric power consumption not the electric power consumption predicted by the electric power consumption attribute. Alternatively, the power cost per unit power consumption may be calculated based on the power consumption.
Further, the calculated power cost may be calculated by dividing the simulation period into a plurality of sub-periods and showing the result. Further, the power cost is the power cost attribute used to calculate the power cost, the representative value of the power consumption attribute, or the value calculated by an example, and the re-simulation is immediately shown by changing these values. It may be a power cost with such a dynamic function. That is, although a graph of power cost is temporarily displayed, the values used as power cost attributes and power consumption attributes are displayed on a display, etc., and the values displayed on the display are managed by power consumers and power cost simulation devices. It can be configured so that a person can change the graph, and when the recalculation button or the like is pressed after the change, a new calculation is immediately performed and the graph is dynamically changed. Therefore, the arithmetic unit can be configured to have a dynamic function type arithmetic result arithmetic means so that the arithmetic result itself is a dynamic function that accepts a change of a variable.
「選択後電力コストシミュレーション結果出力部」とは、電力コスト演算部での演算結果である選択後電力コストシミュレーション結果を出力する機能を有する。出力は不揮発性メモリ、主メモリ、に出力されたのちにディスプレイに表示されたり、ネットワークを介して電力コストシミュレーション装置と通信をしている端末に対して出力されたり、するように構成してもよい。さらにはプリンターや印刷機から紙に印刷等されて出力されるように構成してもよい。また複数の出力形式で同時に出力されるように構成してもよい。例えばインターネットを介して閲覧させるためにウエブページとして出力されるように構成するとともに、電子メールやＳＮＳなどの電力需要者が利用している端末で閲覧可能となるように構成することもできる。もちろん音声で出力されてもよい。さらに、選択後電力コストシミュレーション結果には、単に金銭単位等のコストのみでなく、シミュレーションの各期に選択された電力供給種別を特定するための情報や、その電力供給種別が選択された理由、さらに、他の電力供給種別を選択した場合との比較などを含めたものであってもよい。さらに、その電力コストシミュレーションを行うにあたって想定した事情（原油価格などの燃料価格の変動予想、為替の変動予想）などを含めてもよい。なお出力がウエブページなどを介して行われる場合には、電力コスト属性や電力消費属性の各変数をウエブページ上で操作変更でき、その変更結果もダイナミックに閲覧できるように構成してもよい。 The “selected power cost simulation result output unit” has a function of outputting a selected power cost simulation result which is a calculation result in the power cost calculation unit. The output is output to the non-volatile memory, the main memory, and then displayed on the display, or to the terminal communicating with the power cost simulation device via the network. Good. Further, the printer or the printing machine may be configured to print on paper and output. Further, it may be configured to output in a plurality of output formats at the same time. For example, it can be configured so that it is output as a web page for browsing via the Internet, and can be configured so that it can be browsed on a terminal used by electric power consumers such as electronic mail and SNS. Of course, it may be output as voice. Furthermore, the power cost simulation result after selection is not only the cost in units of money, but also information for identifying the power supply type selected in each period of the simulation, and the reason why the power supply type is selected, Further, it may include comparison with the case where another power supply type is selected. Furthermore, it is possible to include the circumstances (forecast of fluctuations in fuel prices such as crude oil prices, forecasts of fluctuations in foreign exchange), etc. that were assumed in the power cost simulation. If the output is performed via a web page or the like, the variables of the power cost attribute and the power consumption attribute can be changed on the web page, and the change result can be dynamically viewed.
図２３は、シミュレーション結果の出力内容の一例を示す図である。この一例では、従来の電力料金では１年間で「２、６０５万円」であったのが、選択部での時系列に選択された電力供給種別の選択に従ってシミュレーション期間に電力を消費した場合の電力コストによれば１年間で「２、０５８万円」ということになる。この例では、１年間で「５４７万円」の電力コスト削減になるということが一見して分かるようになっている。 FIG. 23 is a diagram showing an example of the output contents of the simulation result. In this example, the conventional electric power charge was “2,6050,000 yen” for one year, but when the electric power was consumed during the simulation period according to the selection of the power supply type selected in time series in the selection unit. According to the electricity cost, it will be "20,580,000 yen" in one year. In this example, it can be seen at a glance that the electric power cost will be reduced by "5.47 million yen" in one year.

以下、本実施形態における電力コストシミュレーション装置について、機能的構成、ハードウェア構成及び処理の流れについて、順に説明する。 Hereinafter, the functional configuration, the hardware configuration, and the flow of processing of the power cost simulation device according to the present embodiment will be sequentially described.
＜機能的構成＞

FIG. 7 is a diagram showing a functional configuration of the power cost simulation apparatus according to this embodiment. The power cost simulation device according to the present embodiment includes a power consumption attribute acquisition unit (0701), a power cost attribute acquisition unit (0702), a simulation period acquisition unit (0703), and a power cost simulation formula holding unit (0704). , A selection unit (0705), a power cost calculation unit (0706), and a power cost simulation result comparison output unit (0707). The contents of each function will be specifically described below. Each function except the power cost simulation result comparison output unit is the same as that of the first embodiment, and therefore the description will be limited to the function of the power cost simulation result comparison output unit.
「電力コストシミュレーション結果比較出力部」とは、複数の電力供給種別について演算された電力コストシミュレーション結果を比較可能に出力する。例えば、図１４に示すような出力をするものである。この図では各月に太平洋電力、東海電力、日本電力、大和電力のそれぞれのコストが示されている。このように同時期に複数の電力供給種別についての電力コストを算出して比較可能に出力することによって、各電力供給種別を相互にコスト面から比較可能とする。
　「電力コストシミュレーション演算部」を有するように構成し、これによって同時期に複数種類の電力供給種別の電力コストを算出するように構成することもできる。例えば、同月に前述のように太平洋電力、東海電力、日本電力、大和電力のそれぞれのコストを算出する。この算出は各電力供給種別の電力供給属性と、電力需要者の電力消費属性と、それぞれの電力供給種別の電力コストシミュレーション演算式と、に基づいて演算される。
　「電力コスト取得部」を有するように構成し、電力コストシミュレーション演算部の機能は電力コストシミュレーション装置外で行うように構成することも考えられる。電力コスト取得部は、蓄積されている各電力供給種別の同時期の電力コストを取得し、前記電力コストシミュレーション結果比較出力部に渡すように構成してもよい。
　「表示部」を有するように構成するのが好ましい。表示部は比較対象となる各電力供給種別の電力コストを数値で表して表形式にして表示してもよいし、数値をグラフ化して表示するように構成することもできる。また、複数の電力供給種別の同時期の比較結果の中から最低コストの電力供給種別の電力コストを他の電力コストと識別することが容易になるように表示することが好ましい。識別容易とするためには、最低の電力コストの値を太字で表したり、他と異なる色彩で表したりすることで実現できる。さらに、電力供給種別がカーソルなどのポインターをグラフ上に置くことで表示されるように構成することもできる。
　なお、比較結果の表示の方式としては、異なるシミュレーション期間の同一の電力供給種別の電力コストを比較可能に表示するように構成することも考えられる。例えば発電所の休止期間と、その休止していた発電所が再稼働した機関とでは、電力供給者（電力供給種別）の課金ポリシーが変更されることがあり、そのポリシーの変更の前後を比較するなどが可能となる。 The “power cost simulation result comparison output unit” outputs the power cost simulation results calculated for a plurality of power supply types in a comparable manner. For example, the output is as shown in FIG. In this figure, each month's costs for Pacific Electric Power, Tokai Electric Power, Japan Electric Power, and Yamato Electric Power are shown. In this way, the power costs for a plurality of power supply types are calculated and output in a comparable manner at the same time, so that the power supply types can be compared with each other in terms of cost.
It may be configured to have a “power cost simulation calculation unit”, and thereby to be configured to calculate power costs of a plurality of types of power supply at the same time. For example, in the same month, the costs of Pacific Power, Tokai Electric Power, Japan Electric Power, and Yamato Electric Power are calculated as described above. This calculation is performed based on the power supply attribute of each power supply type, the power consumption attribute of the power consumer, and the power cost simulation calculation formula of each power supply type.
It is also conceivable that it is configured to have a “power cost acquisition unit” and that the function of the power cost simulation calculation unit is performed outside the power cost simulation device. The power cost acquisition unit may be configured to acquire the accumulated power cost of each power supply type at the same time and pass it to the power cost simulation result comparison output unit.
It is preferable to have a "display section". The display unit may display the power cost of each power supply type to be compared in a numerical form in a tabular form, or may display the numerical values in a graph. Further, it is preferable to display the power cost of the lowest cost power supply type from other power costs from the comparison result of a plurality of power supply types at the same time so that it can be easily distinguished from other power costs. In order to make the identification easy, it can be realized by expressing the value of the lowest power cost in bold or in a different color. Further, the power supply type can be displayed by placing a pointer such as a cursor on the graph.
As a method of displaying the comparison result, it may be possible to display the power costs of the same power supply type in different simulation periods in a comparable manner. For example, the charging policy of the power supplier (power supply type) may change between the period when the power plant was suspended and the organization where the suspended power plant was restarted. Compare the changes before and after the policy was changed. It becomes possible to do it.

　本実施形態は、電力需要者の電力消費量と、電力供給種別ごとの電力コスト属性と、後記する電力料金算出の期間である電力料金算出期間を取得し、複数の電力供給種別毎に、需要者の電力消費量と電力供給種別で定められている電力コスト属性とに応じて電力料金算出期間で時系列に電力供給種別ごとの電力コストを算出するための演算式である電力コスト算出演算式を保持し、電力消費量と電力コスト属性と電力コスト算出演算式とに基づいて複数の電力供給種別の中で最も電力コストが低額となる電力供給種別を電力料金算出期間で時系列に選択する電力料金算出装置を提供する。 In the present embodiment, the power consumption of the power consumer, the power cost attribute for each power supply type, and the power charge calculation period, which is the period for calculating the power charge described later, are acquired, and the demand is calculated for each of the plurality of power supply types.

An electric power charge calculation device is provided.
以下、本実施形態における電力料金算出装置について、機能的構成、ハードウェア構成及び処理の流れについて、順に説明する。
「電力供給種別」「電力コスト属性」の定義は，実施形態１で述べたことと同様である。 Hereinafter, the functional configuration, the hardware configuration, and the flow of processing of the power charge calculation device according to the present embodiment will be sequentially described.
The definitions of “power supply type” and “power cost attribute” are the same as those described in the first embodiment.
＜機能的構成＞
図２４は、本実施形態における電力料金算出装置の機能的構成を示す図である。本実施形態における電力料金算出装置は、電力消費量取得部（２５０１）と電力コスト属性取得部（２５０２）と電力料金算出期間取得期間取得部（２５０３）と電力コスト算出演算式保持部（２５０４）と選択部（２５０５）を有する。以下、機能的構成については、具体的に各機能の内容につき説明する。 <Functional configuration>
FIG. 24 is a diagram showing a functional configuration of the power rate calculation device in the present embodiment. The power charge calculation device according to the present embodiment includes a power consumption acquisition unit (2501), a power cost attribute acquisition unit (2502), a power charge calculation period acquisition period acquisition unit (2503), and a power cost calculation formula holding unit (2504). And a selection unit (2505). Hereinafter, regarding the functional configuration, the content of each function will be specifically described.
「電力消費量取得部」とは、電力需要者の電力消費属性を取得する機能を有する。「電力消費量」とは、時系列での実際の電力消費量を示すものである。時系列とは、例えば、年、月、週などが挙げられる。 The “power consumption acquisition unit” has a function of acquiring the power consumption attribute of the power consumer. The "power consumption" indicates the actual power consumption in time series. Examples of the time series include year, month, and week.
「電力コスト属性取得部」は、実施形態１の説明と同様である。 The “power cost attribute acquisition unit” is the same as that described in the first embodiment.
「電力料金算出期間取得部」とは、電力料金算出の期間である電力料金算出期間を取得する機能を有する。電力料金算出期間は最小の単位はデマンド期間となり複数のデマンド期間の集合で成り立つ。つまり、シミューレーション期間の始期と終期は、デマンド期間の始期であり、同じく終期はデマンド期間の終期である。 The “electric power charge calculation period acquisition unit” has a function of acquiring the electric power charge calculation period, which is a period for calculating the electric power charge. The minimum unit of the power charge calculation period is the demand period, and it consists of a set of multiple demand periods. That is, the start and end of the simulation period are the start of the demand period, and the end is the end of the demand period.
「電力コスト算出演算式保持部」とは、複数の電力供給種別毎に、需要者の電力消費量と電力供給種別で定められている電力コスト属性と、に応じて電力料金算出期間で時系列に電力供給種別ごとの電力コストを算出するための演算式である電力コスト算出演算式を保持する機能を有する。 "Electricity cost calculation formula storage unit" means, for each of multiple power supply types, a time series in the power charge calculation period according to the power consumption of the consumer and the power cost attribute defined by the power supply type. In addition, it has a function of holding a power cost calculation formula, which is a formula for calculating the power cost for each power supply type.
本実施例における「選択部」とは、取得した電力消費量と、取得した電力コスト属性と、保持されている電力コスト算出演算式と、に基づいて複数の電力供給種別の中で最も電力コストが低額となる電力供給種別を電力料金算出期間で時系列に選択する機能を有する。
　電力供給種別の選択をする最小の期間単位は、デマンド期間である。デマンド期間は前述の通りであるので、最も頻繁には３０分間隔で電力供給種別を選択するように設計できる。ただし、これに限定されるものでなく、３０分の自然数倍の期間を電力供給種別の切り替えを行うことができる時間長として選択することができる。電力事業者の切り替えの現実のルールに合わせる必要がない点がこの装置の特徴である。また、この電力供給種別の切り替え期間は、切換期間を選択するように構成することも可能である。その場合には、選択部に切換期間選択手段を設けることが考えられる。 The “selection unit” in the present embodiment is the most power cost among a plurality of power supply types based on the acquired power consumption amount, the acquired power cost attribute, and the stored power cost calculation formula. Has a function of selecting a power supply type with a low price in time series in the power charge calculation period.
The minimum period unit for selecting the power supply type is the demand period. Since the demand period is as described above, it can be designed to select the power supply type most frequently at intervals of 30 minutes. However, the present invention is not limited to this, and a period of a natural number multiple of 30 minutes can be selected as the time length for which the power supply type can be switched. The feature of this device is that it is not necessary to comply with the actual rules for switching between electric power companies. Further, the switching period of the power supply type can be configured to select the switching period. In that case, it is conceivable to provide the selection unit with switching period selection means.
さらに電気料金算出装置は，選択部での選択結果と、その選択された電力供給種別の電力供給属性とに基づいて電力料金算出期間内でのその電力需要者に対する電力料金の算出する電力料金算出部をさらに有していても良い。 Further, the electricity rate calculation device calculates the electricity rate for the electricity consumer within the electricity rate calculation period based on the selection result of the selection section and the electricity supply attribute of the selected electricity supply type. You may further have a part.
以上のとおり、複数の電力供給種別の中で最も低額である電力供給種別を時系列ごとに選択するという基本的な発想は実施形態１と同様であるが、予測というシミュレーションではなく、実際の電力消費量に応じて，時系列ごとに最も低額な電力供給種別を選択して電力料金を課金するという点が実施形態１とは異なるものである。 As described above, the basic idea of selecting the lowest-priced power supply type among a plurality of power supply types for each time series is the same as that of the first embodiment, but not the simulation of prediction but the actual power consumption. This is different from the first embodiment in that the lowest priced power supply type is selected for each time series according to the consumption amount and the power charge is charged.
