Description

本発明は、電力託送を促進すると共に電力託送業務を効率化することのできる託送業務支援システムに関する。   The present invention relates to a consignment work support system capable of promoting electric power consignment and improving the efficiency of electric power consignment work.

近年、電力自由化に伴い電力託送の必要性が生じる一方、電力取引市場の活性化が望まれ、一般電気事業者にとっては電力託送業務の効率化や供給信頼度の維持が問題となっている。   In recent years, the need for power consignment has arisen with the liberalization of power, while the activation of the power trading market is desired. For general electric utilities, there is a problem in improving the efficiency of power consignment operations and maintaining supply reliability. .

電力託送に関する従来技術として、たとえば特許文献１では、供給支障が生じるか否かを事前に判定する技術が提案されている。この技術は、電力系統に属する負荷の状況と発電の状況を入力し、託送要求にもとづいて供給信頼度を計算するというものである。   As a conventional technique related to power consignment, for example, Patent Document 1 proposes a technique for determining in advance whether or not a supply failure occurs. In this technology, the load status and the power generation status belonging to the power system are input, and the supply reliability is calculated based on the consignment request.

また、特許文献２では、電力需給計画とＰＰＳ（特定規模電気事業者）のための託送業務に関連した技術として、エリアを複数に区分して、エリアの損失率やエリア間の託送料金を考慮して供給電力に対する支払額の総和と託送料金の合計が最小になるような電力を供給するように需給計画を作成するシステムが提案されている。
特開２０００−２６１９６３号公報 特開２００３−１８００３０号公報 In Patent Document 2, as a technology related to power supply and demand planning and consignment work for PPS (specific electric utility), areas are divided into a plurality of areas, and the loss rate of areas and consignment charges between areas are considered. Thus, a system for creating a supply and demand plan has been proposed so as to supply electric power that minimizes the sum of the sum of payments for the supplied power and the consignment fee.
JP 2000-261963 A JP 2003-180030 A

しかしながら、上述の従来の技術は、託送取引業務の効率化を目的としたものではないため、託送取引が活発になるにつれて託送計画データの提出期限のフォローなど一般電気事業者の業務が煩雑となる。また、託送取引の増加に伴う電力供給信頼度の維持のための負担が大きくなる。さらに、ＰＰＳ（特定規模電気事業者）など市場参加者にとっても計画と実績等の管理を自身で行う必要があり、少なからず労力を要する。これら一般電気事業者や市場参加者の負担は電力取引の活性化を阻害することになる。   However, the above-described conventional technology is not intended to improve the efficiency of the consignment transaction business, and as the consignment transaction becomes active, the work of general electric utilities such as following the deadline for submission of consignment plan data becomes complicated. . Moreover, the burden for maintaining the power supply reliability accompanying the increase in consignment transactions increases. Furthermore, it is necessary for market participants such as PPS (specific electric utility) to manage plans and results themselves, which requires a lot of labor. The burden on these general electric utilities and market participants hinders the activation of power trading.

本発明は、上述のかかる事情に鑑みてなされたものであり、市場参加者の電力取引を促進すると共に高い電力供給信頼度を実現することができ、託送業務の効率を向上させることのできる託送業務支援システムを提供することを目的とする。   The present invention has been made in view of the above-described circumstances, and is capable of promoting power trading of market participants and realizing high power supply reliability and improving the efficiency of consignment work. The purpose is to provide a business support system.

上記の目的を達成するため、本発明に係る託送業務支援システムは、中立機関システム、同時同量システムおよびＷＥＢサーバと接続し、電力取引の市場参加者の託送計画データを収集して託送可能量を算定する託送業務支援システムであって、前記中立機関システムから送られてくる市場参加者の所定時間帯ごとの希望託送量を入力する取引支援手段と、前記入力した希望託送量をもとに作成された計画潮流と、系統の運用容量と、マージンとを用いて託送可能量を算定し、混雑が生じた場合は所定の条件によって前記計画潮流を調整して託送可否を判定し、当該判定結果を出力する託送業務支援手段と、前記同時同量システムから送られてくる市場参加者の所定時間ごとの託送実績データを収集し、当該市場参加者の託送計画データと託送実績データとを対比可能にして市場参加者に提供するためのＷＥＢデータを作成して前記ＷＥＢサーバにアップロードする同時同量監視支援データ作成手段と、を備えたことを特徴とする。   In order to achieve the above object, a consignment work support system according to the present invention is connected to a neutral institution system, a simultaneous equal amount system and a WEB server, collects consignment plan data of market participants in power transactions, and can be consigned. A transaction support means for calculating a desired consignment amount for each predetermined time zone of a market participant sent from the neutral institution system, and based on the inputted desired consignment amount The amount of consignment is calculated using the created planned flow, grid operating capacity, and margin, and if congestion occurs, the planned flow is adjusted according to the prescribed conditions to determine whether or not consignment is possible. Consignment service support means for outputting the results, and the collection results data of the market participants sent from the simultaneous equal volume system every predetermined time are collected, and the consignment plan data of the market participants and the consignment are collected. Characterized in that it includes at the same time the same amount monitoring support data creating means to create a WEB data for and enables comparing the performance data to provide to the market participants to upload to the WEB server, the.

本発明では、中立機関システムで市場参加者の託送計画や希望託送量を集約し、この中立機関システムと託送業務支援システムとを接続することによって、市場参加者の託送計画データ等を入力する。この入力した託送計画データを用い混雑処理等を行い託送可否の判定結果を中立機関システムを経由して市場参加者へ通知する。また、同時同量システムを介して市場参加者の実績データを収集して、計画データと実績データとの時間ごとの対比データをＷＥＢサーバを通して市場参加者に提供する。なお、ＷＥＢサーバを通して時間ごとの託送可能量データを提供するのも有効である。   In the present invention, the consignment plan of the market participant and the desired consignment amount are collected by the neutral institution system, and the consignment plan data of the market participant is input by connecting the neutral institution system and the consignment work support system. Using this inputted consignment plan data, congestion processing and the like are performed, and the judgment result of consignment acceptance is notified to the market participant via the neutral organization system. In addition, the performance data of the market participant is collected through the simultaneous equal amount system, and the hourly comparison data of the plan data and the performance data is provided to the market participant through the WEB server. It is also effective to provide consignable amount data for each hour through the WEB server.

好ましくは、託送業務支援手段は、所定時刻以後に受信した希望託送量は時刻の早い順に優先順位を付して待ち状態とし、入力した希望託送量をもとに連系線に流れる電気量を算出して連系線の運用容量に基づいて定められる所定値を超過している場合は、前記所定時刻までに受信した希望託送量については、均等割によって託送可能量を算定し、その後、待ち状態の希望託送量について優先順位の高いものから託送可否を決定するようにすると良い。   Preferably, the consignment work support means prioritizes the desired consignment amount received after a predetermined time and puts it in a waiting state in order of early time, and calculates the amount of electricity flowing through the interconnection line based on the inputted desired consignment amount. If the calculated value exceeds the predetermined value determined based on the operating capacity of the interconnection line, the requested consignment amount received by the predetermined time is calculated as the consignable amount by an equal split, and then waiting It is preferable to determine whether or not consignment is possible from the highest priority order regarding the desired amount of consignment.

本発明では、需給計画算定の期限をもとに定めた時刻を基準にして、その前後で託送取引の演算の仕方を変える。すなわち、所定の基準時刻までに受信した希望託送量については、均等割によって託送可能量を算定し、基準時刻以降については、早い順に託送枠を割り付ける。需給計画の算定タイミングと託送取引のタイミングとを連動させ、さらにタイミングの前後で託送取引の演算方法を変えることによって、需給計画作成の円滑化と市場参加者に取引の期限意識を持たせることができる。   In the present invention, the calculation method of the consignment transaction is changed before and after the time determined based on the deadline for calculating the supply and demand plan. That is, for the desired consignment amount received by a predetermined reference time, the consignable amount is calculated by an equal distribution, and after the reference time, the consignment frame is assigned in order of speed. By synchronizing the calculation timing of supply and demand plans and the timing of consignment transactions, and further changing the calculation method of consignment transactions before and after the timing, it is possible to facilitate the creation of demand and supply plans and to make market participants aware of the deadlines of transactions it can.

より好ましくは、前記所定時刻は、エリアに供給する発電機種別ごとに定めるようにすると良い。火力、水力、原子力等の発電機種別によって動作特性がことなるため、期限タイミングを発電機種別ごとに変えて、種別ごとの発電計画に基づいて期限が来ていない分については託送要求を受け付けることによってスポット的な電力取引を活発にすることができる。   More preferably, the predetermined time may be determined for each type of generator supplied to the area. Because the operating characteristics differ depending on the type of generator such as thermal power, hydropower, nuclear power, etc., change the deadline timing for each generator type, and accept consignment requests for those that have not expired based on the power generation plan for each type Can activate spot electricity trading.

また、本発明に係る託送業務支援システムでは、前記託送業務支援手段は、連系線の一の方向について容量超過となった場合は、他の方向の託送要求を一律拒否したり、受け付けたりするのではなく、その容量超過となった要因（制約条件）によって、当該条件に基づいて他の方向の託送希望を受け付けるか否かを判定することを特徴とする。   In the consignment work support system according to the present invention, the consignment work support means uniformly rejects or accepts the consignment request in the other direction when the capacity is exceeded in one direction of the interconnection line. Instead, it is characterized in that it is determined whether or not to accept a consignment request in another direction based on the condition (constraint condition) that has exceeded the capacity.

たとえば、両方向の電気量のバランスが取れていたほうが、周波数や電圧安定性は良くなると考えられるので、一の方向の容量超過となったときの制約条件がこれらのときは他の方向の託送要求を受け付けて託送可能量を計算する。一方、制約条件が熱容量の場合は、逆方向の電力を増加させることは全体的に連系線の熱容量を悪化させることになるので、逆方向の託送要求は受け付けないようにする。この判定をＷＥＢで公開することによって、有効な託送要求のみを受け付け、無意味な託送要求を排除することができるので、業務効率を向上させることができる。   For example, if the amount of electricity in both directions is balanced, the frequency and voltage stability are considered to be better.Therefore, when the constraint condition when the capacity is exceeded in one direction, the consignment request in the other direction is required. Is received and the consignable amount is calculated. On the other hand, when the constraint condition is heat capacity, increasing the power in the reverse direction will deteriorate the heat capacity of the interconnection line as a whole, so the consignment request in the reverse direction is not accepted. By publishing this determination on the WEB, only valid consignment requests can be accepted and meaningless consignment requests can be eliminated, so that business efficiency can be improved.

また、本発明に係る託送業務支援システムは、同時同量を実質的に達成する時間間隔、託送計画提出期限からの遅れ時間、供給安定度のうち少なくともいずれか一つに基づいて託送料を算定する託送料演算手段を備えたことを特徴とする。   In addition, the consignment work support system according to the present invention calculates the consignment shipping fee based on at least one of the time interval for substantially simultaneously achieving the same amount, the delay time from the consignment plan submission deadline, and the supply stability. It is characterized in that it includes a consignment shipping fee calculation means.

これら各条件によって託送料を可変にすることにより、同時同量制御や託送計画提出期限の遵守、電力安定供給のための設備の点検保守等が自然に実行されるようになる。   By making the consignment postage variable according to each of these conditions, simultaneous control of the same amount, observance of the consignment plan submission deadline, inspection and maintenance of facilities for stable power supply, etc. are naturally performed.

好ましくは、所定時刻に市場参加者からの託送計画の受信の有無を確認し、受信無しの場合は催促通知を実行するようにすると良い。   Preferably, it is preferable to check whether or not a consignment plan has been received from a market participant at a predetermined time, and to execute a reminder notification if there is no reception.

本発明では、催促通知を行うことによって託送計画の送信を促し、需給計画作成の円滑化を図ることができる。   In the present invention, it is possible to facilitate the transmission of a consignment plan by making a reminder notification, thereby facilitating the creation of a supply and demand plan.

ここで、「運用容量」とは、想定した故障が発生した場合においても電力系統の信頼度を維持可能な電力潮流値を表し、熱容量（設備容量を含む）、安定度、電圧安定性（電圧低下）、周波数維持等、系統運用上の制約条件にかかる値のうち、最小の値をいう。   Here, “operating capacity” refers to the power flow value that can maintain the reliability of the power system even when an assumed failure occurs, and includes heat capacity (including equipment capacity), stability, and voltage stability (voltage). This is the minimum value among the values related to system operation constraints such as frequency maintenance.

「計画潮流値」とは、地域（エリア）間連系線を介した託送を行う電気事業者が提出する託送計画値を合算した値あるいは差し引いた値をいう。   The “planned tidal current value” refers to a value obtained by adding or subtracting the planned consignment value submitted by the electric power company that performs consignment via the interconnection line between regions.

「マージン」とは、異常時等の対応として、一般電気事業者の送電部門が地域間連系設備を介して他の一般電気事業者との間で応援融通を送電するために確保しておく量を意味する。   A “margin” is reserved for the power transmission department of a general electric utility to transmit support assistance to and from other general electric utilities through inter-regional facilities as a countermeasure in case of an abnormality. Means quantity.

「市場参加者」は、電力取引市場に参加する、発電事業者および小売事業者をいう。発電事業者とは、電力市場に参加する、発電側の事業者のことをいい、特定規模電気事業者、自家発電所有者、卸電気事業者、一般電気事業者などからなる。小売事業者とは、電力市場に参加する、需要側の事業者のことをいい、特定規模電気事業者、一般電気事業者からなる。   “Market participants” refers to power producers and retailers who participate in the electricity trading market. The power generation company refers to a business on the power generation side that participates in the power market, and includes a specific scale electric power company, a private power generation owner, a wholesale electric power company, a general electric power company, and the like. A retailer refers to a demand-side operator who participates in the power market, and consists of a specific-scale electric utility and a general electric utility.

「中立機関」とは、電力系統利用協議会など市場参加者との託送計画の調整等を行う機関をいう。   “Neutral organization” means an organization that coordinates consignment plans with market participants such as the Power System Utilization Council.

本発明によれば、託送業務支援システムに中立機関システムや同時同量システム等を介して計画データや実績データを収集し、ＷＥＢを通して市場参加者の利用に供する情報を提供するので、市場参加者の託送取引が活発になっても業務効率が低下せず、電力取引市場参加者の電力取引を促進すると共に託送料を種々の条件によって可変にすることにより高い電力供給信頼度を実現することができる。   According to the present invention, since the plan data and the actual data are collected in the consignment work support system through the neutral institution system, the simultaneous equal amount system, etc., and the information provided for the use of the market participant is provided through the WEB, the market participant Even if the consignment transaction becomes active, the business efficiency does not decrease, and it is possible to realize high power supply reliability by promoting the power transaction of the power transaction market participants and making the consignment fee variable according to various conditions it can.

また、按分抑制処理と低順位抑制処理の適用を託送計画提出期限を基準に変更するようにしたので、託送計画提出期限の遵守が期待できる。   In addition, since the application of prorated control processing and low-order control processing is changed based on the consignment plan submission deadline, compliance with the consignment plan submission deadline can be expected.

託送可能量＝連系線の運用容量―（マージン＋計画潮流） ・・・（１）     Amount that can be entrusted = Operational capacity of interconnection line-(Margin + Planned current) (1)

ここで、運用容量の決定要因としては、熱容量、安定度、周波数、あるいは作業に伴う抑制などがある。   Here, factors that determine the operating capacity include heat capacity, stability, frequency, and suppression accompanying work.

マージンは、時間単位の変動量とその時間帯の売電を計画している発電業者の発電機の故障率をもとに決定する。故障率は、発電機種別ごとに初期値を定め、実績によって補正していく。   The margin is determined based on the amount of fluctuation in time units and the failure rate of the generator of the power generator who plans to sell power during that time period. For the failure rate, an initial value is determined for each generator type, and the failure rate is corrected according to the actual results.

この託送可能量算定処理において、順方向、逆方向の時間単位の潮流値を業務端末５１ａ〜５１ｃ上に表示し、上記（１）式による算定結果として、運用容量、マージン、計画潮流、託送可能量を連系線ごとに系統図上に表示する。また、ピークの演算を行い、ピークが逸脱している連系線や時間帯を識別表示する。   In this entrustable amount calculation process, the tidal current values in the forward and reverse time units are displayed on the business terminals 51a to 51c, and the operation capacity, margin, planned tidal current, and entrustment are possible as the calculation results by the above formula (1). The quantity is displayed on the system diagram for each interconnection line. Further, the peak calculation is performed, and the interconnection line and the time zone where the peak deviates are identified and displayed.

図２は、計算結果の表示画面例である。３０分ごとに順方向、逆方向の夫々について、託送可能量が表示される。また、運用容量とマージンについてはそれぞれ変更ボタン（図中（ａ），（ｂ））が表示され、これらの値を変更することができるようになっている。なお、変更入力された場合は、託送可能量算定手段３１によって再計算される。   FIG. 2 is an example of a calculation result display screen. The consignable amount is displayed for each of the forward direction and the reverse direction every 30 minutes. Further, change buttons ((a) and (b) in the figure) are displayed for the operational capacity and the margin, respectively, so that these values can be changed. When the change is input, it is recalculated by the entrustable amount calculation means 31.

また、このときの算定根拠を保存しておき、図３に示すような算定根拠画面で算定根拠表示ボタンをクリックしたときに、算定根拠を表示させる。また、図３において、連系線名（送電線名、フェンス名を含む）をリストボックスで選択・表示可能になっており（図中（ｃ））、運用容量、マージン、託送可能量、計画潮流の項目ごと、時間単位ごとにデータが表示される。   Also, the calculation basis at this time is stored, and the calculation basis is displayed when the calculation basis display button is clicked on the calculation basis screen as shown in FIG. In FIG. 3, the names of interconnection lines (including transmission line names and fence names) can be selected and displayed in a list box ((c) in the figure), and the operating capacity, margin, consignable amount, plan Data is displayed for each tidal item and time unit.

算定結果の表示については、図４に示すように、送電線やフェンス別に運用容量、マージン、計画潮流、託送可能量を表示させるようにすると良い。さらに、日付時刻入力ボタンによって日時を指定すると（図中（ｄ））、その日時のデータ値が系統図上に表示され（図中（ｅ））、マージンが所定値以下になったときに色別表示させることによって、オペレータの注意を喚起する。   As for the display of the calculation result, as shown in FIG. 4, it is preferable to display the operation capacity, margin, planned tidal current, and consignable amount for each transmission line and fence. Further, when the date and time is designated by the date / time input button ((d) in the figure), the data value of the date and time is displayed on the system diagram ((e) in the figure), and the color is displayed when the margin is equal to or less than the predetermined value. The operator's attention is alerted by displaying it separately.

各連系線を指定することによって、図５に例示するように、連系線ごとに時間帯（あるいは日、月、年ごと）の運用容量等の各データの表示を行う。   By designating each interconnection line, as shown in FIG. 5, each data such as the operation capacity in the time zone (or every day, month, year) is displayed for each interconnection line.

（託送可否判定支援処理）
託送可否判定支援手段３３は、託送可能量算定処理で計算した結果を端末画面上に託送可否の判定結果と共に表示する。図６は、その表示例である。連系線ごとに、各時間単位で順方向、逆方向別に潮流値を表示して、託送不可の時間帯があるか否かの判定結果を最下欄に表示している。託送不可有表示エリア（図中（ｆ））は、託送可能量算出後、託送不可が生じた場合に表示し、託送不可無表示エリア（図中（ｇ））は、託送可能量算出後、託送不可が生じなかった場合に表示する。 (Consignment acceptance support processing)
The entrustment availability determination support means 33 displays the result calculated in the entrustable amount calculation process together with the assessment result of entrustment availability on the terminal screen. FIG. 6 shows an example of the display. For each interconnected line, the tidal current value is displayed for each time unit in the forward direction and the reverse direction, and the determination result of whether or not there is a time zone that cannot be entrusted is displayed in the bottom column. The non-consignable display area ((f) in the figure) is displayed when the impossible of consignment occurs after calculating the consignable amount, and the non-consignable display area ((g) in the figure) Displayed when no consignment has occurred.

（混雑処理）
混雑処理支援手段３４は、計画潮流および運用容量の設定・変更に伴って混雑が生じた場合、各市場参加者の計画潮流値の合計が託送可能量を超えるような場合は、計画潮流の抑制処理を実行する。 (Congestion processing)
The congestion processing support means 34 suppresses the planned flow when congestion occurs due to the setting / change of the planned flow and the operation capacity, and the total planned flow value of each market participant exceeds the consignable amount. Execute the process.

抑制処理は、按分抑制処理または低順位抑制処理によって行い、抑制託送銘柄、計画潮流、運用容量、託送可能量を算定する。   The suppression process is performed by a proportional distribution suppression process or a low-order suppression process, and the suppression consignment brand, the planned tide, the operational capacity, and the consignable amount are calculated.

以下、図７と図８を用いて、按分抑制処理と低順位抑制処理について説明する。
（按分抑制処理：均等割り）
混雑が発生した潮流方向の融通を均等に抑制する。図７は、按分抑制処理の説明図である。いま、市場参加者ａ，ｂ，ｃの計画潮流値がそれぞれＡ，Ｂ，Ｃであり、その合計が託送可能量を超過していたとすると、以下の式によってそれぞれを均等抑制して、抑制後の電力量Ａ’，Ｂ’，Ｃ’を算出する。 Hereinafter, the proportionality suppression process and the low-order suppression process will be described with reference to FIGS. 7 and 8.
(Apportionment suppression processing: equally divided)
Constrain the tidal current in the direction of congestion evenly. FIG. 7 is an explanatory diagram of the apportioning suppression process. Now, if the planned tidal current values of market participants a, b, and c are A, B, and C, respectively, and the sum exceeds the amount that can be consigned, each is controlled equally by Power amounts A ′, B ′, and C ′ are calculated.

Ａ’＝託送可能量・Ａ／（Ａ＋Ｂ＋Ｃ）
Ｂ’＝託送可能量・Ｂ／（Ａ＋Ｂ＋Ｃ）
Ｃ’＝託送可能量・Ｃ／（Ａ＋Ｂ＋Ｃ） A '= Amount that can be sent and A / (A + B + C)
B '= consignable amount / B / (A + B + C)
C ′ = consignable amount / C / (A + B + C)

（低順位抑制処理）
予め融通区分ごとに優先順位を付け、混雑が発生した潮流方向の融通のうち、低順位のものから順次抑制・中止する。 (Low order suppression processing)
Priorities are assigned to each accommodation section in advance, and the congestion in the tidal direction where congestion has occurred is sequentially suppressed and stopped from the lowest order.

図８によれば、市場参加者ａ，ｂ，ｃの計画潮流値の合計Ａ＋Ｂ＋Ｃは託送可能量を超えるため、優先順位の高いものから順にその計画潮流値を認めていき、託送可能量を超えることになる市場参加者ｃの計画潮流値については、合計値が託送可能量になるまで認め、それを超える分については中止するというものである。   According to FIG. 8, since the total A + B + C of the planned tidal values of market participants a, b, and c exceeds the consignable amount, the planned tidal values are recognized in order from the highest priority and exceed the consignable amount. The planned trend value of the market participant c will be accepted until the total value reaches the consignable amount, and the excess will be canceled.

図９は、混雑処理支援手段３４による表示出力画面例である。送電線名・フェンス名ごとに抑制方法として、按分抑制処理か低順位抑制処理かの抑制タイプを設定入力する。また、抑制量として、抑制後の運用容量と計画潮流値が入力可能になっている。   FIG. 9 is an example of a display output screen by the congestion processing support means 34. As the suppression method for each transmission line name / fence name, the suppression type of the distribution suppression process or the low order suppression process is set and input. Moreover, the operation capacity and the planned tidal current value after the suppression can be input as the suppression amount.

なお、上記のように予め設定された抑制タイプによって一律混雑の調整を行うのではなく、以下の如く、市場参加者の託送計画（託送要求）の提出期限を基準に抑制タイプを切り替えて演算するようにしても良い。すなわち、託送の提出期限の所定時刻以後に受信した希望託送量は時刻の早い順に優先順位を付して待ち状態とし、入力した希望託送量をもとに連系線に流れる電気量を算出して連系線の運用容量に基づいて定められる所定値を超過している場合は、前記所定時刻までに受信した希望託送量については、均等割によって託送可能量を算定し、その後、待ち状態の希望託送量について優先順位の高いものから託送可否を決定するようにする。   Instead of adjusting the congestion uniformly by using the preset suppression type as described above, the calculation is performed by switching the suppression type based on the deadline for submitting the consignment plan (consignment request) of the market participant as follows. You may do it. In other words, the requested delivery amount received after the predetermined time of the submission deadline is prioritized in order from the earliest time in a waiting state, and the amount of electricity flowing through the interconnection line is calculated based on the entered requested delivery amount. In the case where the predetermined value determined based on the operating capacity of the interconnection line is exceeded, for the desired consignment amount received up to the predetermined time, the consignable amount is calculated by an equal distribution, and then the waiting state Whether or not consignment is possible is determined from the one with the highest priority for the desired amount of consignment.

以下、図１０を用いて、この混雑時抑制処理の手順を詳述する。
まず、託送要求を受信すると（Ｓ１０１で「Ｙｅｓ」）、提出期限内か否かを判定し（Ｓ１０２）、提出期限を経過していれば（Ｓ１０２で「Ｙｅｓ」）、受信した託送要求を待ち行列に格納する（Ｓ１０３）。一方、提出期限内ならば（Ｓ１０２で「Ｎｏ」）、受信した託送要求を演算用ファイルに保存する。 Hereinafter, the procedure of the congestion suppression process will be described in detail with reference to FIG.
First, when a consignment request is received (“Yes” in S101), it is determined whether or not it is within the submission deadline (S102). If the submission deadline has passed (“Yes” in S102), the received consignment request is awaited. Store in the matrix (S103). On the other hand, if it is within the submission deadline (“No” in S102), the received consignment request is stored in the calculation file.

その後、託送可能量を算定するタイミングか否かを判定して（Ｓ１０５）、算定タイミングでなければ、再びステップＳ１０１に戻る。   Thereafter, it is determined whether or not it is the timing for calculating the consignable amount (S105), and if it is not the calculation timing, the process returns to step S101 again.

ステップＳ１０５で託送可能量を算定するタイミングであれば（Ｓ１０５で「Ｙｅｓ」）、演算用ファイルに保存されているデータを抽出して託送可能量算定手段３１によって託送可能量を計算する（Ｓ１０６）。   If it is the timing for calculating the consignable amount in step S105 (“Yes” in S105), the data stored in the calculation file is extracted and the consignable amount calculating means 31 calculates the consignable amount (S106). .

計算の結果、計画値の合計が運用容量を超過していた場合は（Ｓ１０７で「Ｙｅｓ」）、均等割りによって計算をして（Ｓ１０８）、その計算結果を出力する（Ｓ１０９）。   As a result of the calculation, if the total of the plan values exceeds the operating capacity (“Yes” in S107), the calculation is performed by equal division (S108), and the calculation result is output (S109).

その後、託送余裕があるか否かを判定して（Ｓ１１０）、託送余裕がある場合は（Ｓ１１０で「Ｙｅｓ」）、託送可否判定支援手段３３を起動する。託送可否判定支援手段３３は、起動されると待ち行列から順に託送要求を抽出して（Ｓ１１１）、託送可否の判定を行い（Ｓ１１２）、託送可の場合は（Ｓ１１３で「Ｙｅｓ」）、計画潮流に組み込む（Ｓ１１４）。待ち行列に他の託送要求が有れば、ステップＳ１１０に戻り、全託送要求について終了すれば（Ｓ１１５で「Ｙｅｓ」）、託送計画データ、託送可能量を情報公開する（Ｓ１１６）。一方、ステップＳ１１０で託送余裕がない場合は、直ちにステップＳ１１６に移行する。   Thereafter, it is determined whether or not there is a consignment allowance (S110). If there is a consignment allowance (“Yes” in S110), the consignment availability determination support means 33 is activated. When activated, the delivery permission / inhibition determination support means 33 extracts the request for delivery in order from the queue (S111), determines the availability of the delivery (S112), and when the delivery is permitted (“Yes” in S113), the plan Incorporate into the current (S114). If there is another consignment request in the queue, the process returns to step S110, and if all consignment requests are completed (“Yes” in S115), information on the consignment plan data and the consignable amount is disclosed (S116). On the other hand, if there is no margin for delivery in step S110, the process immediately proceeds to step S116.

（託送可否判定支援処理の変形例）
運用容量の制約条件としては、熱容量（設備容量を含む）、電圧安定性（電圧低下）、周波数維持等がある。これらの制約条件のうち、電圧安定性や周波数維持については一の方向の潮流が他の方向の潮流にはあまり影響を与えないが、熱容量については互いに影響を与えるため、このような両方向に影響を当たるような制約条件を特定の制約条件として管理する。 (Modified example of processing for determining whether or not consignment is accepted)
The operating capacity constraints include heat capacity (including equipment capacity), voltage stability (voltage drop), and frequency maintenance. Among these constraints, the power flow in one direction has little effect on the power flow in the other direction for voltage stability and frequency maintenance, but the heat capacity has an influence on each other. Is managed as a specific constraint condition.

そして、連系線の順方向、逆方向別にこれらの制約条件に基づいて運用容量を決定し、託送可否の決定を行うが、一の方向について託送可能量を計算し、容量超過となった場合は、容量超過となる制約条件に基づいて他の方向の託送希望の受付を停止するか否かの判定を行う。   Then, the operational capacity is determined based on these constraints for each forward and backward direction of the interconnection line, and whether or not consignment is possible is determined, but the consignable amount is calculated in one direction and the capacity is exceeded Determines whether to stop accepting the request for consignment in the other direction based on the constraint condition that the capacity is exceeded.

したがって、図１０のステップＳ１１１〜Ｓ１１４に示す託送可否判定支援処理の手順は次のように改善することができる。図１１は、この変形例による託送可否判定処理の手順を示すフローチャートである。   Therefore, the procedure of the delivery permission determination support process shown in steps S111 to S114 in FIG. 10 can be improved as follows. FIG. 11 is a flowchart showing the procedure of the consignment permission determination process according to this modification.

まず、待ち行列から方向別の託送要求データを抽出し（Ｓ２０１）、託送可否の判定を行う（Ｓ２０２）。具体的には、その時点の計画潮流に託送要求量を加算して運用容量を超えるか否かを判定し、超えない場合は託送可、超える場合は託送不可とする。そして、託送可能な場合は（Ｓ２０３で「Ｙｅｓ」）、その託送要求を受け付けると共に待ち行列を更新し、次の待ち状態の託送要求データを抽出できる状態にする（Ｓ２０４）。一方、ステップＳ２０３で「Ｎｏ」の場合、すなわち託送不可の場合は、その方向の託送要求の受付を停止する（Ｓ２０５）。そして、その判定の基準となった制約条件が逆方向に影響をあたえる特定の制約条件に該当するか否かを判定して（Ｓ２０６、Ｓ２０７）、特定の制約条件に該当する場合は（Ｓ２０７で「Ｙｅｓ」）、他の方向の託送要求についても受付を停止する（Ｓ２０８）。
これにより、有効な託送要求のみを効率的に受け付けることができる。 First, the direction-specific consignment request data is extracted from the queue (S201), and it is determined whether consignment is possible (S202). Specifically, it is determined whether or not the operating capacity is exceeded by adding the requested amount to the planned trend at that time. Then, if the consignment is possible (“Yes” in S203), the consignment request is accepted and the queue is updated so that the next consignment request data in the waiting state can be extracted (S204). On the other hand, if “No” in step S203, that is, if the consignment is impossible, the acceptance of the consignment request in that direction is stopped (S205). Then, it is determined whether or not the constraint condition that is the criterion for the determination corresponds to a specific constraint condition that affects the reverse direction (S206, S207). “Yes”), the acceptance of the consignment request in the other direction is also stopped (S208).
Thereby, it is possible to efficiently accept only valid consignment requests.

（公開データ更新処理）
公開データ更新手段３５は、予め設定されたデータを作成・更新した場合、中立機関システム７や社外向け通信サーバ３ａへそのデータを送信する。送信データとしては、たとえば、データ種別が連系線託送可能量関係データとしては、託送可能量、運用容量、マージン、計画潮流などのデータがあり、データ種別が需給計画については、需要予想、供給力予想などのデータがある。 (Public data update process)
When the preset data is created / updated, the public data update unit 35 transmits the data to the neutral engine system 7 and the external communication server 3a. As the transmission data, for example, there are data such as the amount that can be consigned, operational capacity, margin, planned flow, etc., as the data type is data related to the amount of consignment that can be connected, and the data type is demand forecast, supply, etc. There is data such as force prediction.

これらは、データ種別ごとに管理部門に対応するＩＤ、パスワードが設定されており、該当する管理部門のみが、そのデータ種別のデータにアクセス可能になっている。   In these, an ID and a password corresponding to the management department are set for each data type, and only the corresponding management department can access the data of the data type.

<市場参加者需給計画確認処理>
市場参加者需給計画確認手段２６は、発電業者の発電計画と、小売業者の需給計画に対する供給予備力・予備率を算定し、図１２の画面表示を行う。ここで、発電業者と、小売業者別に時間単位ごとの発電量あるいは販売量を表示し、また、予備力（ＭＷと％）を表示する。 <Market participant supply / demand plan confirmation process>
The market participant supply / demand plan confirmation means 26 calculates the power reserve of the power generator and the supply reserve capacity / reserve ratio for the retailer's supply / demand plan, and displays the screen of FIG. Here, the power generation amount or the sales amount for each time unit is displayed for each power generator and retailer, and the reserve power (MW and%) is displayed.

<取引部門データ連係処理>
取引部門データ連係手段２７は、取引部門の業務端末との間で需給計画データの送受信を行う。ＡＤＳ８の需給計画などのデータを受信して取引部門の業務端末へデータを送信する。また、取引部門から受信した需給計画などのデータをＡＤＳ８へ送信する。 <Transaction department data linkage processing>
The transaction department data linking means 27 transmits and receives demand / supply plan data to / from business terminals of the transaction department. Receives data such as the demand and supply plan of ADS8 and transmits the data to the business terminal of the transaction department. Further, data such as a supply and demand plan received from the trading department is transmitted to the ADS 8.

このときの需給計画送受信画面は、水力、火力、原子力などの発電種別ごとに時間単位で受け渡しを行うようにするとよい。   The supply and demand plan transmission / reception screen at this time may be transferred in units of time for each type of power generation such as hydropower, thermal power, and nuclear power.

<同時同量監視支援データ作成処理>
同時同量監視支援データ作成手段２９は、同時同量監視システム６から受信した市場参加者の所定時間ごとの託送実績データをもとに市場参加者の託送計画データと託送実績データとを時間ごとに対比した表示データを作成して、通信サーバ３ａへ送信する。このデータは、インターネット網４のＷＥＢサーバ５に保存され、市場参加者からアクセス可能な状態におかれる。また、この表示データは、需給計画電力、需給実績電力別に所定時間（３０分）周期に更新される。 <Same simultaneous monitoring support data creation process>
The simultaneous same amount monitoring support data creating means 29 obtains the market participant's consignment plan data and consignment result data for each hour based on the market participant's consignment result data received from the simultaneous same amount monitoring system 6 every predetermined time. Display data in comparison with is created and transmitted to the communication server 3a. This data is stored in the WEB server 5 of the Internet network 4 and is accessible by market participants. In addition, this display data is updated at a predetermined time (30 minutes) period for each supply / demand planned power and actual power supply / demand power.

<その他の処理>
このほか、作業計画支援手段２４は、中立機関システム７へ送信する作業計画用データを作成する。また、広域給電業務支援手段２５は、発電種別ごと、市場参加者ごとに、所定時間単位（たとえば３０分）での需給予想を行い、この需給予測、実績データの作成および全国融通に必要な需給計画、融通申し出データを作成する。 <Other processing>
In addition, the work plan support means 24 creates work plan data to be transmitted to the neutral engine system 7. Further, the wide area power supply business support means 25 makes a supply and demand forecast in a predetermined time unit (for example, 30 minutes) for each type of power generation and each market participant, and the supply and demand necessary for this supply and demand forecast, creation of performance data, and nationwide interchange. Create planning and accommodation offer data.

本実施の形態によれば、託送業務支援システムに中立機関システムや同時同量システム等を介して計画データや実績データを収集し、ＷＥＢを通して市場参加者のための同時同量データや託送可能量（空き容量）などの情報を提供するので、市場参加者の託送取引が円滑になる。また、取引の活性化に伴う業務効率の低下を防止することができる。   According to the present embodiment, plan data and actual data are collected in a consignment work support system via a neutral institution system or a simultaneous equivalence system, etc., and the same equivalence data and consignable amount for market participants are collected through the WEB. Since information such as (free space) is provided, the consignment transaction of market participants becomes smooth. In addition, it is possible to prevent a decrease in business efficiency accompanying the activation of transactions.

さらに、按分抑制処理と低順位抑制処理の適用を託送計画提出期限を基準に切り替えることにより、託送計画提出期限の遵守が期待できる。   Furthermore, by switching the application of the apportionment suppression process and the low-order suppression process based on the consignment plan submission deadline, compliance with the consignment plan submission deadline can be expected.

次に本発明の第２の実施の形態を説明する。
図１３は本実施の形態による託送業務支援システム１を構成する託送業務支援サーバ１０の機能ブロック図である。 Next, a second embodiment of the present invention will be described.
FIG. 13 is a functional block diagram of the consignment work support server 10 constituting the consignment work support system 1 according to this embodiment.

図１の託送業務支援サーバ１０との違いは、演算部１２に、託送料演算手段３６を追加したことである。その他の機能については同様であるので、同一機能には同一符号を付して説明を省略する。   The difference from the consignment work support server 10 of FIG. 1 is that a consignment shipping cost calculation means 36 is added to the calculation unit 12. Since the other functions are the same, the same functions are denoted by the same reference numerals and description thereof is omitted.

託送料演算手段３６は、取引支援手段２２や同時同量監視システム６から受け取ったデータを用いて図１４に示す演算条件によって連系線ごとの託送料金を計算して、公開データ更新手段３５等を介してリアルタイムに市場参加者へ提示する。   The commission postage calculation means 36 calculates the consignment fee for each interconnection line according to the calculation conditions shown in FIG. 14 using the data received from the transaction support means 22 and the simultaneous same amount monitoring system 6, and the public data update means 35 etc. To market participants in real time.

託送料を決定する要因としては、図１４に示すように、需要予測からの超過、連系線ごとの託送可能量、市場参加者の発電設備の故障率（供給安定度）、同時同量基準からの逸脱、託送計画の提出期限からの遅れなどがある。   Factors that determine consignment shipping costs include, as shown in FIG. 14, excess from demand forecast, consignable amount for each interconnected line, failure rate (supply stability) of power generation facilities of market participants, and the same amount standard There is a deviation from the time limit and a delay from the submission deadline of the consignment plan.

各要因についてさらに詳細に説明する。需要予測からの超過は、当初立案した需給計画に対して所定値以上需要が上回ったときに託送料を安くするものである。連系線ごとの託送可能量については、連系線の託送可能量が所定量以下になった場合に託送可能量の減少に伴って託送料を上げるものである。故障率は、市場参加者の発電機の故障実績を託送料に反映させるものである。   Each factor will be described in more detail. The excess from the demand forecast is to reduce the consignment shipping fee when the demand exceeds a predetermined value with respect to the initially planned supply and demand plan. As for the consignable amount for each interconnection line, when the consignable amount for the interconnection line is equal to or less than a predetermined amount, the consignment postage is increased with a decrease in the consignable amount. The failure rate reflects the failure history of the market participants' generators in the commission.

同時同量基準からの逸脱については、基準値を逸脱した分について託送料を変動させるものである。同時同量基準の逸脱ランクとして、所定時間（たとえば３０分）の同時同量を達成できなかった場合の超過量によって管理しても良いし、同時同量を満足する時間で管理するようにしても良い。たとえば、３０分同時同量は守れなかったものの４５分は満足した場合は、そのランクに応じた託送料にするなどである。逆に３０分でなく、もっと短い時間間隔（たとえば１５分）で同時同量基準を満たしている場合は、託送料を下げるようにしても良い。   Regarding deviation from the same amount standard, the shipping fee is changed for the deviation from the standard value. The deviation rank based on the same amount standard may be managed based on the excess amount when the same amount for a predetermined time (for example, 30 minutes) cannot be achieved, or it may be managed in a time that satisfies the same amount. Also good. For example, if the same amount for 30 minutes could not be observed but 45 minutes were satisfied, the consignment shipping fee was set according to the rank. Conversely, when the simultaneous equal amount criterion is satisfied at a shorter time interval (for example, 15 minutes) instead of 30 minutes, the commission fee may be lowered.

託送計画の提出期限については、市場参加者からの託送計画の提出期限を基準に託送料を変動させるというものである。なお、提出期限については、発電種別ごとに託送要求の期限をセットするようにすると良い。   The deadline for submitting the consignment plan is to change the consignment fee based on the deadline for submitting the consignment plan from market participants. As for the deadline for submission, it is preferable to set the deadline of the consignment request for each power generation type.

そして、要因ごとのデータを変数として次のように処理する。
すなわち、予測からの超過電力量（ｘ１）、連系線の託送可能量の逆数（１／（ｘ２＋α））、故障率実績（ｘ３）、同時同量基準を逸脱しだ電力量（ｘ４）、提出期限からの遅れ時間（ｘ５）を変数として、各変数にそれぞれ重み係数ａ〜ｅを加味して、次の式によって変動託送料を用いる。 Then, the data for each factor is processed as a variable as follows.
That is, the excess power amount (x1) from the prediction, the reciprocal number (1 / (x2 + α)) of the consignable amount of the interconnection line, the actual failure rate (x3), the power amount (x4) that deviates from the simultaneous same amount standard, Using the delay time (x5) from the submission deadline as a variable, and adding the weighting factors a to e to each variable, the variable contract shipping fee is used according to the following equation.

変動託送料＝基準託送料―ａ・ｘ１＋ｂ・１／（ｘ２＋α）
＋ｃ・ｘ３＋ｄ・ｘ４＋ｅ・ｘ５ ・・・（２） Variable shipping fee = Standard shipping fee-a · x 1 + b · 1 / (x 2 + α)
+ C · x 3 + d · x 4 + e · x 5 (2)

この変動託送料を市場参加者との取引のタイミングや実績によって都度計算して適用する。計算した託送料は、取引支援手段２２を介して中立機関システム７へ送られ、また、公開データ更新手段３５を介してＷＥＢ公開される。   This variable shipping fee is calculated and applied each time depending on the timing and performance of transactions with market participants. The calculated consignment shipping fee is sent to the neutral institution system 7 via the transaction support means 22 and is made public via the public data update means 35.

本実施の形態によれば、託送料金を種々の要因によって変動するようにしたので、市場原理に基づいた調整が可能となり、託送業務に関する調整手続きの負担が軽減し、託送取引を促進することができる   According to the present embodiment, since the consignment fee fluctuates depending on various factors, adjustment based on the market principle is possible, the burden of the adjustment procedure related to consignment work is reduced, and consignment transactions can be promoted. it can

具体的には、需要予測超過については当初立案した需給計画を予想以上上回るような場合は、託送料を下げることによって、市場参加者との託送取引を促進する一方で一般電気事業者の電力設備を稼動しないようにしてピークに備えた予備分として確保しておくことができる。   Specifically, if the excess demand forecast exceeds the originally planned supply and demand plan, the consignment fee will be lowered to promote consignment transactions with market participants, while the power facilities of general electric utilities Can be secured as a reserve for the peak.

連系線ごとの託送可能量については、託送可能量に十分余裕があるときは、託送料を安くし、託送可能量に余裕が無いときは、託送料を高くすることによって、連系線の容量の平準化を図ることができる。なお、このとき市場参加者（発電業者）の発電設備位置を考慮するようにすれば、託送可能量が安いエリアに位置する発電設備を用いた売電が行われるようになるので、より連系線容量の平準化効果を上げることができる。   Regarding the consignable amount for each interconnected line, if there is a sufficient margin for the consignable amount, the consignment fee will be reduced, and if there is no surplus for the consignable amount, the consignment fee will be increased. Capacity leveling can be achieved. At this time, if the location of the power generation facilities of market participants (power producers) is taken into account, power will be sold using power generation facilities located in areas where the consignable amount is cheap. The line capacity leveling effect can be increased.

発電設備の故障率実績を決定要因にすることによって、市場参加者の自発的な設備保守を促し、一般電気事業者のバックアップ負担を軽減し、市場参加者が増えた場合でも電力供給安定度の低下を防止することができる。   By making the failure rate of power generation facilities a determinant, it encourages market participants to voluntarily maintain their facilities, reduces the backup burden on general electric utilities, and improves power supply stability even when the number of market participants increases. A decrease can be prevented.

同時同量基準の逸脱についても同様な効果を奏するが、特に画一的な基準を守ったか否かではなく、同時同量制御を実行している時間間隔によって託送料を安くすることによって、リアルタイムの需給バランス調整のインセンティブとなり、市場参加者が増加することによる一般電気事業者の安定度維持の負担の増加を緩和することができる。
また、託送計画の提出期限の遅れについては、提出期限の厳守を促すことができる。 The same effect can be achieved for deviations from the same amount standard, but not by whether or not a uniform standard was observed, but by reducing the commission fee according to the time interval during which the same amount control is performed, As an incentive to adjust the supply and demand balance, the increase in the burden of maintaining the stability of general electric utilities due to the increase in market participants can be mitigated.
In addition, regarding the delay in the submission deadline of the consignment plan, strict adherence to the deadline for submission can be encouraged.
