Description

本発明は、電力需給管理システム、電力需給管理装置、及び電力需給管理方法に関する。 The present invention relates to a power supply and demand management system, a power supply and demand management device, and a power supply and demand management method.

電力は貯蔵することが困難であるから、電力の需要と供給とのバランスを常に一致させる同時同量を達成する必要がある。例えば、一般電気事業者は数秒単位で同時同量を達成する必要があり、新電力事業者は３０分単位で同時同量を達成する必要がある。新電力事業者が同時同量を達成することができなかった場合（計画値と実績値との差＝インバランスが発生した場合）には、３０分単位毎の電力の需要と供給との差分を調整するインバランス調整が行われる。 Since electricity is difficult to store, it is necessary to achieve simultaneous equal amounts that always balance the supply and demand of electricity. For example, a general electric utility needs to achieve the same amount every few seconds, and a new electric power company needs to achieve the same amount every 30 minutes. If the new electric power company cannot achieve the same amount at the same time (difference between the planned value and the actual value = imbalance occurs), the difference between the supply and demand of electricity every 30 minutes. Imbalance adjustment is performed to adjust.

具体的には、新電力事業者による発電量が不足した場合には、新電力事業者が一般電気事業者から不足分の電力を買い取ることで、電力の需要と供給との差分が調整される。これに対し、新電力事業者による発電量が余った場合には、一般電気事業者が新電力事業者から余剰分を買い取ることで、電力の需要と供給との差分が調整される。 Specifically, when the amount of power generated by the new electric power company is insufficient, the new electric power company purchases the shortage of electric power from the general electric power company, and the difference between the demand and supply of electric power is adjusted. .. On the other hand, when the amount of power generated by the new electric power company is surplus, the general electric power company purchases the surplus from the new electric power company, and the difference between the supply and demand of electric power is adjusted.

以下の特許文献１には、従来の電力制御システムの一例が開示されている。具体的に、以下の特許文献１には、同時同量の原則の下、電力の需要を設定された目標値内に制御するとともに、目標値の設定に電力の供給能力を反映可能な広域多拠点電力制御システムが開示されている。 The following Patent Document 1 discloses an example of a conventional power control system. Specifically, in Patent Document 1 below, under the principle of simultaneous equal amount, the demand for electric power can be controlled within the set target value, and the power supply capacity can be reflected in the setting of the target value. The base power control system is disclosed.

ところで、近年、再生可能エネルギー発電施設が急激に増加している。このような発電施設の急激な増加により、配電設備の容量の制限や需給バランスの崩れを懸念して、逆潮流の認可がおりない発電施設が増えている。 By the way, in recent years, the number of renewable energy power generation facilities has increased rapidly. Due to such a rapid increase in power generation facilities, there are an increasing number of power generation facilities that are not licensed for reverse power flow due to concerns about capacity restrictions on distribution facilities and imbalance between supply and demand.

ここで、逆潮流の認可を受けている発電施設が停止した場合には、配電設備の容量に空きが生ずることになる。しかしながら、現状では、配電設備の容量の空きがあるにも拘わらず、逆潮流の認可を受けていない発電施設ではインバランス調整を行うことができないことから、逆潮流の認可を受けていない発電施設を有効に活用できているとは言えない状況である。 Here, if the power generation facility licensed for reverse power flow is stopped, the capacity of the distribution facility will be vacant. However, at present, despite the availability of power distribution equipment capacity, imbalance adjustment cannot be performed at power generation facilities that have not been licensed for reverse power flow, so power generation facilities that have not been licensed for reverse power flow. It cannot be said that we are able to make effective use of.

本発明は、上記事情に鑑みてなされたものであり、逆潮流の認可を受けていない発電施設を有効に活用することができる電力需給管理システム、電力需給管理装置、及び電力需給管理方法を提供することを目的とする。 The present invention has been made in view of the above circumstances, and provides a power supply and demand management system, a power supply and demand management device, and a power supply and demand management method capable of effectively utilizing a power generation facility that has not been licensed for reverse power flow. The purpose is to do.

上記課題を解決するために、本発明の一態様による電力需給管理システム（１）は、電力系統（ＰＳ）への逆潮流の認可を受けている少なくとも１つの第１発電施設（２０ａ〜２０ｃ）と、前記電力系統への逆潮流の認可を受けていない少なくとも１つの第２発電施設（１０）と、前記第１発電施設から前記電力系統への逆潮流ができなくなる異常が生じた場合に、前記第２発電施設から前記電力系統への逆潮流を一時的に行わせる電力需給管理装置（３０）と、を備える。 In order to solve the above problems, the power supply and demand management system (1) according to one aspect of the present invention is at least one first power generation facility (20a to 20c) licensed for reverse power flow to the power system (PS). When at least one second power generation facility (10) that has not been approved for reverse power flow to the power system and an abnormality that prevents reverse power flow from the first power generation facility to the power system occur. A power supply and demand management device (30) for temporarily performing reverse power flow from the second power generation facility to the power system is provided.

また、本発明の一態様による電力需給管理システムは、前記電力需給管理装置が、前記第２発電施設が前記電力系統への逆潮流を行う余裕がある場合に、前記電力系統に逆潮流する電力量が、前記第１発電施設及び前記第２発電施設が接続される配電設備の容量を超えないように制御する。 Further, in the electric power supply and demand management system according to one aspect of the present invention, when the electric power supply and demand management device can afford to reverse power flow to the electric power system, the electric power that reverse power flows to the electric power system. The amount is controlled so as not to exceed the capacity of the power distribution facility to which the first power generation facility and the second power generation facility are connected.

また、本発明の一態様による電力需給管理システムは、前記電力需給管理装置が、前記第１発電施設に異常が生じた場合に、異常が生じた前記第１発電施設以外の他の前記第１発電施設の発電量を増加させても必要な電力が賄えないときに、前記第２発電施設から前記電力系統への逆潮流を一時的に行わせる。 Further, in the power supply and demand management system according to one aspect of the present invention, when the power supply and demand management device has an abnormality in the first power generation facility, the first power supply and demand management system other than the first power generation facility in which the abnormality has occurred. When the required power cannot be supplied even if the power generation amount of the power generation facility is increased, the reverse power flow from the second power generation facility to the power system is temporarily performed.

また、本発明の一態様による電力需給管理システムは、前記電力需給管理装置が、異常が生じた前記第１発電施設が復帰した場合、又は異常が生じた前記第１発電施設以外の他の前記第１発電施設で必要な電力が賄えるようになった場合には、前記第２発電施設から前記電力系統への逆潮流を停止させる。 Further, in the power supply and demand management system according to one aspect of the present invention, when the power supply and demand management device returns to the first power generation facility in which an abnormality has occurred, or other than the first power generation facility in which an abnormality has occurred, the above. When the required electric power can be supplied by the first power generation facility, the reverse power flow from the second power generation facility to the electric power system is stopped.

When an abnormality occurs, the reverse power flow from the second power generation facility (10), which has not been approved for reverse power flow to the power system, is temporarily performed to the power system.

本発明の一態様による電力需給管理方法は、電力系統（ＰＳ）への逆潮流の認可を受けている第１発電施設（２０ａ〜２０ｃ）から電力需給管理装置（３０）に、前記電力系統への逆潮流ができなくなる異常が生じた旨を通知するステップ（Ｓ１１）と、前記異常が生じた旨が通知された場合に、前記電力需給管理装置が、前記電力系統への逆潮流の認可を受けていない第２発電施設（１０）から前記電力系統への逆潮流を一時的に行わせるステップ（Ｓ１５）と、を有する。 The power supply and demand management method according to one aspect of the present invention is from the first power generation facility (20a to 20c) licensed for reverse power flow to the power system (PS) to the power supply and demand management device (30) to the power system. The step (S11) of notifying that an abnormality has occurred that prevents reverse power flow, and when the notification of the abnormality has occurred, the power supply and demand management device approves the reverse power flow to the power system. It has a step (S15) of temporarily performing reverse power flow from the second power generation facility (10) that has not received the power system to the power system.

本発明によれば、逆潮流の認可を受けていない発電施設を有効に活用することができるという効果がある。 According to the present invention, there is an effect that a power generation facility that has not been approved for reverse power flow can be effectively utilized.

以下、図面を参照して本発明の一実施形態による電力需給管理システム、電力需給管理装置、及び電力需給管理方法について詳細に説明する。 Hereinafter, the electric power supply / demand management system, the electric power supply / demand management device, and the electric power supply / demand management method according to the embodiment of the present invention will be described in detail with reference to the drawings.

〈電力需給管理システム〉
図１は、本発明の一実施形態による電力需給管理システムの要部構成を示すブロック図である。図１に示す通り、本実施形態の電力需給管理システム１は、発電施設１０（第２発電施設）、発電施設２０ａ〜２０ｃ（第１発電施設）、及びアグリゲータ３０（電力需給管理装置）を備えており、需要家ＥＣに対して電力の供給を行う。この電力需給管理システム１は、インバランスが発生しないように、例えば、需要家ＥＣによる電力の需要と、発電施設１０及び発電施設２０ａ〜２０ｃによる電力の供給とを管理する。 <Power supply and demand management system>
FIG. 1 is a block diagram showing a main configuration of a power supply / demand management system according to an embodiment of the present invention. As shown in FIG. 1, the power supply and demand management system 1 of the present embodiment includes a power generation facility 10 (second power generation facility), power generation facilities 20a to 20c (first power generation facility), and an aggregator 30 (power supply and demand management device). It supplies electric power to the consumer EC. The power supply and demand management system 1 manages, for example, the demand for power by the consumer EC and the supply of power by the power generation facilities 10 and the power generation facilities 20a to 20c so that imbalance does not occur.

発電施設１０は、例えば太陽光発電装置、風力発電装置、地熱発電装置、その他の再生可能エネルギーを用いで発電を行う再生可能エネルギー発電装置を備える。本実施形態では、発電施設１０には太陽光発電装置が設けられているとする。発電施設１０は、電力系統ＰＳに接続されている。ここで、発電施設１０は、電力系統ＰＳへの逆潮流の認可を受けていない発電施設である。 The power generation facility 10 includes, for example, a solar power generation device, a wind power generation device, a geothermal power generation device, and other renewable energy power generation devices that generate power using renewable energy. In the present embodiment, it is assumed that the power generation facility 10 is provided with a solar power generation device. The power generation facility 10 is connected to the power system PS. Here, the power generation facility 10 is a power generation facility that has not been approved for reverse power flow to the power system PS.

発電施設１０が電力系統ＰＳへの逆潮流の認可を受けていないのは、逆潮流の許可を申請した時点において、例えば、配電設備の容量の制限ため、或いは、他の発電施設２０ａ〜２０ｃとの関係において需給バランスの崩れの懸念のため、電力系統ＰＳへの逆潮流の認可がおりなかったためである。以下、電力系統ＰＳへの逆潮流の認可を受けていない発電施設を、「無認可発電施設」ということがある。 The power generation facility 10 has not been approved for reverse power flow to the power system PS at the time of applying for the reverse power flow permission, for example, due to the limitation of the capacity of the distribution equipment, or with other power generation facilities 20a to 20c. This is because the reverse power flow to the power system PS was not approved due to concerns about the imbalance between supply and demand. Hereinafter, a power generation facility that has not been licensed for reverse power flow to the power system PS may be referred to as an “unlicensed power generation facility”.

発電施設１０は、電力系統ＰＳへの逆潮流の認可を受けていないため、発電施設１０で発電された電力を電力系統ＰＳに逆潮流させることができない。このため、平常運転時に発電施設１０で発電された電力は、発電施設１０の構内の負荷に供給されて消費される。また、発電施設１０では、発電された電力が電力系統ＰＳに逆潮流することがないように、発電量が構内の需要量を超えないように調整される。 Since the power generation facility 10 has not been approved for reverse power flow to the power system PS, the power generated by the power generation facility 10 cannot be reverse power flow to the power system PS. Therefore, the electric power generated by the power generation facility 10 during normal operation is supplied to the load on the premises of the power generation facility 10 and consumed. Further, in the power generation facility 10, the amount of power generation is adjusted so as not to exceed the amount of demand in the premises so that the generated power does not flow back to the power system PS.

発電施設２０ａ〜２０ｃは、例えば太陽光発電装置、風力発電装置、地熱発電装置、その他の再生可能エネルギーを用いで発電を行う再生可能エネルギー発電装置を備える。本実施形態では、発電施設２０ａ，２０ｂには太陽光発電装置が設けられており、発電施設２０ｃには風力発電装置が設けられているとする。発電施設２０ａ〜２０ｃは、発電施設１０と同様に、電力系統ＰＳに接続されている。ここで、発電施設２０ａ〜２０ｃは、電力系統ＰＳへの逆潮流の認可を受けている発電施設である。 The power generation facilities 20a to 20c include, for example, a solar power generation device, a wind power generation device, a geothermal power generation device, and other renewable energy power generation devices that generate power using renewable energy. In the present embodiment, it is assumed that the power generation facilities 20a and 20b are provided with a photovoltaic power generation device, and the power generation facility 20c is provided with a wind power generation device. The power generation facilities 20a to 20c are connected to the power system PS in the same manner as the power generation facility 10. Here, the power generation facilities 20a to 20c are power generation facilities that are licensed for reverse power flow to the power system PS.

発電施設２０ａ〜２０ｃが電力系統ＰＳへの逆潮流の認可を受けることができたのは、逆潮流の許可を申請した時点において、例えば、配電設備の容量に余裕があったため、或いは、需給バランスの崩れの懸念がなかったため、電力系統ＰＳへの逆潮流の認可がおりたためである。以下、電力系統ＰＳへの逆潮流の認可を受けている発電施設を、「認可発電施設」ということがある。尚、発電施設１０，２０ａ〜２０ｃは、共通の配電設備（電線、変電所）に接続されているものとする。 The power generation facilities 20a to 20c were able to obtain the approval of reverse power flow to the power system PS at the time of applying for the permission of reverse power flow, for example, because there was a margin in the capacity of the distribution equipment, or the supply-demand balance. This is because there was no concern about the collapse of the power system, and the reverse power flow was approved for the power system PS. Hereinafter, a power generation facility that has been licensed for reverse power flow to the power system PS may be referred to as a “licensed power generation facility”. It is assumed that the power generation facilities 10, 20a to 20c are connected to common power distribution facilities (electric wires, substations).

〈電力需給管理装置〉
アグリゲータ３０は、電力需給管理システム１の核をなす装置であり、例えば、インバランスが発生しないように電力の需要及び供給を管理する。アグリゲータ３０は、発電施設１０，２０ａ〜２０ｃに設けられた制御装置（図示省略）と通信可能に構成されており、発電施設１０，２０ａ〜２０ｃの発電量を示す情報を取得し、必要に応じて、発電施設１０，２０ａ〜２０ｃの動作を制御する指示を行う。また、アグリゲータ３０は、需要家ＥＣに設けられた各種の機器（図示省略）と通信可能に構成されており、需要家ＥＣにおいて消費される電力量（消費電力量）を示す情報を取得する。 <Power supply and demand management device>
The aggregator 30 is a device that forms the core of the electric power supply and demand management system 1, and manages, for example, the supply and demand of electric power so that imbalance does not occur. The aggregator 30 is configured to be communicable with control devices (not shown) provided in the power generation facilities 10, 20a to 20c, acquires information indicating the amount of power generation in the power generation facilities 10, 20a to 20c, and if necessary. Then, an instruction is given to control the operation of the power generation facilities 10, 20a to 20c. Further, the aggregator 30 is configured to be able to communicate with various devices (not shown) provided in the consumer EC, and acquires information indicating the electric energy (power consumption) consumed in the consumer EC.

また、アグリゲータ３０は、日本卸電力取引所（ＪＥＰＸ：Japan Electric Power Exchange）のコンピュータと通信可能に構成されており、日本卸電力取引所に対して行った取引を示す情報（入札情報）を取得する。尚、日本卸電力取引所に対して行った取引を示す情報は、例えばキーボード等のような入力装置を用いて、アグリゲータ３０に入力するようにしても良い。 In addition, the aggregator 30 is configured to be able to communicate with the computer of the Japan Electric Power Exchange (JEPX), and acquires information (bid information) indicating transactions made to the Japan Electric Power Exchange. To do. Information indicating a transaction made to the Japan Electric Power Exchange may be input to the aggregator 30 using an input device such as a keyboard.

アグリゲータ３０、発電施設１０，２０ａ〜２０ｃに設けられた制御装置、需要家ＥＣに設けられた各種の機器、及び日本卸電力取引所のコンピュータは、不図示のネットワークを介して通信可能に接続されている。このネットワークは、インターネット等のワイド・エリア・ネットワーク（ＷＡＮ）であっても良く、ローカル・エリア・ネットワーク（ＬＡＮ）であっても良い。また、ネットワークを介した通信は、有線通信であっても良く、無線通信であっても良い。即ち、アグリゲータ３０と、発電施設１０，２０ａ〜２０ｃ等との間の通信形態は、特に制限されることはなく、任意の通信形態を採用することができる。 The aggregator 30, the control devices installed in the power generation facilities 10, 20a to 20c, the various devices installed in the consumer EC, and the computer of the Japan Electric Power Exchange are connected in a communicable manner via a network (not shown). ing. This network may be a wide area network (WAN) such as the Internet, or may be a local area network (LAN). Further, the communication via the network may be wired communication or wireless communication. That is, the communication mode between the aggregator 30 and the power generation facilities 10, 20a to 20c and the like is not particularly limited, and any communication mode can be adopted.

アグリゲータ３０は、認可発電施設である発電施設２０ａ〜２０ｃにおいて、電力系統ＰＳへの逆潮流ができなくなる異常が生じた場合に、無認可発電施設である発電施設１０から電力系統ＰＳへの逆潮流を一時的に行わせる。これは、異常が生じた認可発電施設に代わって無認可発電施設である発電施設１０から電力系統ＰＳへの逆潮流を一時的に行わせることで、発電施設１０を有効に活用するためである。尚、異常が生じた認可発電施設が停止すると配電設備の容量に空きが生ずることになるため、発電施設１０から電力系統ＰＳへの逆潮流を一時的に行わせても、配電設備の容量を超えなければ問題は生じない。 The aggregator 30 causes a reverse power flow from the power generation facility 10 which is an unlicensed power generation facility to the power system PS when an abnormality occurs in the power generation facilities 20a to 20c which are licensed power generation facilities so that the reverse power flow to the power system PS cannot be performed. Let it be done temporarily. This is to make effective use of the power generation facility 10 by temporarily performing reverse power flow from the power generation facility 10 which is an unlicensed power generation facility to the power system PS in place of the licensed power generation facility in which the abnormality has occurred. If the licensed power generation facility where the abnormality occurs is stopped, the capacity of the distribution equipment will be vacant. Therefore, even if the reverse power flow from the power generation facility 10 to the power system PS is temporarily performed, the capacity of the distribution equipment can be increased. If it does not exceed, no problem will occur.

アグリゲータ３０は、例えば、発電施設１０に電力系統ＰＳへの逆潮流を行う余裕がある場合に電力系統ＰＳへの逆潮流を行わせる。つまり、アグリゲータ３０は、発電施設１０の発電量が、少なくとも発電施設１０の構内で必要になる電力量を上回っている場合に電力系統ＰＳへの逆潮流を行わせる。ここで、アグリゲータ３０は、発電施設１０に電力系統ＰＳへの逆潮流を行わせる場合には、発電施設１０，２０ａ〜２０ｃが接続される配電設備の容量を超えないように制御する。 For example, the aggregator 30 causes the power generation facility 10 to perform reverse power flow to the power system PS when it can afford to perform reverse power flow to the power system PS. That is, the aggregator 30 causes reverse power flow to the power system PS when the amount of power generated by the power generation facility 10 exceeds at least the amount of power required in the premises of the power generation facility 10. Here, the aggregator 30 controls the power generation facility 10 so as not to exceed the capacity of the distribution facility to which the power generation facilities 10, 20a to 20c are connected when the power generation facility 10 is made to perform reverse power flow to the power system PS.

尚、電力系統ＰＳ全体が停止する可能性がある場合（例えば、災害時におけるブラックアウトが発生する場合）には、緊急を要するために、アグリゲータ３０は、発電施設１０に電力系統ＰＳへの逆潮流を行う余裕が無くとも、電力系統ＰＳへの逆潮流を行わせるようにしても良い。つまり、アグリゲータ３０は、発電施設１０の発電量が、発電施設１０の構内で必要になる電力量を下回っていても電力系統ＰＳへの逆潮流を行わせるようにしても良い。 If there is a possibility that the entire power system PS will stop (for example, if a blackout occurs in the event of a disaster), the aggregator 30 will reverse the power system PS to the power generation facility 10 in order to require an emergency. Even if there is no room for power flow, reverse power flow to the power system PS may be performed. That is, the aggregator 30 may cause reverse power flow to the power system PS even if the amount of power generated by the power generation facility 10 is less than the amount of power required in the premises of the power generation facility 10.

アグリゲータ３０は、認可発電施設である発電施設２０ａ〜２０ｃに異常が生じた場合に、異常が生じた発電施設（例えば、発電施設２０ａ）以外の他の発電施設（例えば、発電施設２０ｂ，２０ｃ）の発電量を増加させても必要な電力が賄えないときに、無認可発電施設である発電施設１０から電力系統ＰＳへの逆潮流を一時的に行わせる。無認可発電施設である発電施設１０は、本来であれば電力系統ＰＳへの逆潮流が認められないため、電力系統ＰＳへの逆潮流が認められている認可発電施設で、必要な電力を極力賄うようにしている。 When an abnormality occurs in the power generation facilities 20a to 20c which are licensed power generation facilities, the aggregator 30 is a power generation facility (for example, power generation facilities 20b, 20c) other than the power generation facility (for example, the power generation facility 20a) in which the abnormality occurs. When the required power cannot be supplied even if the amount of power generation is increased, the reverse power flow from the power generation facility 10 which is an unlicensed power generation facility to the power system PS is temporarily performed. Since the power generation facility 10, which is an unlicensed power generation facility, normally does not allow reverse power flow to the power system PS, it is a licensed power generation facility that allows reverse power flow to the power system PS, and supplies the necessary power as much as possible. I am doing it.

アグリゲータ３０は、異常が生じた発電施設（例えば、発電施設２０ａ）が復帰した場合、又は異常が生じた発電施設（例えば、発電施設２０ａ）以外の他の発電施設（例えば、発電施設２０ｂ，２０ｃ）で、必要な電力が賄えるようになった場合には、無認可発電施設である発電施設１０から電力系統ＰＳへの逆潮流を停止させる。無認可発電施設である発電施設１０における電力系統ＰＳへの逆潮流は、あくまでも例外的なものであるため、発電施設１０による電力系統ＰＳへの逆潮流が必要なくなった場合には、速やかに停止させるようにしている。 The aggregator 30 may be used when the abnormal power generation facility (for example, power generation facility 20a) is restored, or other power generation facilities (for example, power generation facilities 20b, 20c) other than the abnormal power generation facility (for example, power generation facility 20a). ), When the required power can be supplied, the reverse power flow from the power generation facility 10 which is an unlicensed power generation facility to the power system PS is stopped. Since the reverse power flow to the power system PS in the power generation facility 10 which is an unlicensed power generation facility is an exception to the last, when the reverse power flow to the power system PS by the power generation facility 10 is no longer necessary, it is promptly stopped.

図２は、本発明の一実施形態による電力需給管理方法の一例を示すフローチャートである。尚、図２に示すフローチャートの処理は、認可発電施設である発電施設２０ａ〜２０ｃの何れかにおいて、電力系統ＰＳへの逆潮流ができなくなる異常が生じた場合に開始される。尚、以下では、理解を容易にするために、電力系統ＰＳへの逆潮流ができなくなる異常が発電施設２０ａで生じた場合を例に挙げて説明する。 <Power supply and demand management method>
FIG. 2 is a flowchart showing an example of the power supply / demand management method according to the embodiment of the present invention. The processing of the flowchart shown in FIG. 2 is started when an abnormality occurs in any of the power generation facilities 20a to 20c, which is a licensed power generation facility, so that reverse power flow to the power system PS cannot be performed. In the following, in order to facilitate understanding, a case where an abnormality that prevents reverse power flow to the power system PS occurs in the power generation facility 20a will be described as an example.

図２に示すフローチャートの処理が開始されると、まず、電力系統ＰＳへの逆潮流ができなくなる異常が生じた発電施設２０ａからアグリゲータ３０に対し、逆潮流が不可である異常（電力系統ＰＳへの逆潮流ができなくなる異常）が生じた旨が通知される（ステップＳ１１）。次に、上記の異常が生じていない他の認可発電施設（発電施設２０ｂ，２０ｃ）で発電量の調整が可能であるか否かがアグリゲータ３０で判断される（ステップＳ１２）。 When the processing of the flowchart shown in FIG. 2 is started, first, an abnormality in which reverse power flow to the power system PS is not possible occurs. An abnormality in which reverse power flow is not possible from the power generation facility 20a to the aggregator 30 (to the power system PS). It is notified that the reverse power flow of (step S11) has occurred (step S11). Next, the aggregator 30 determines whether or not the amount of power generation can be adjusted at other licensed power generation facilities (power generation facilities 20b, 20c) in which the above abnormality does not occur (step S12).

他の認可発電施設（発電施設２０ｂ，２０ｃ）で発電量の調整が可能であると判断した場合（ステップＳ１２の判断結果が「ＹＥＳ」の場合）には、他の認可発電施設（発電施設２０ｂ，２０ｃ）の逆潮流電力量を増大させる処理が、アグリゲータ３０によって行われる（ステップＳ１３）。この処理が行われることで、発電施設２０ａで生じた異常によって不足する電力が、発電施設２０ｂ，２０ｃで発電される電力によって賄われることとなる。 If it is determined that the amount of power generation can be adjusted at another licensed power generation facility (power generation facility 20b, 20c) (when the determination result in step S12 is "YES"), the other licensed power generation facility (power generation facility 20b) , 20c) The process of increasing the amount of reverse power flow is performed by the aggregator 30 (step S13). By performing this processing, the power shortage due to the abnormality generated in the power generation facility 20a is covered by the power generated in the power generation facilities 20b and 20c.

これに対し、他の認可発電施設（発電施設２０ｂ，２０ｃ）で発電量の調整が不可能あると判断した場合（ステップＳ１２の判断結果が「ＮＯ」の場合）には、無認可発電施設（発電施設１０）に逆潮流するだけの発電量の余裕があるか否かがアグリゲータ３０で判断される（ステップＳ１４）。無認可発電施設（発電施設１０）に逆潮流するだけの発電量の余裕は無いと判断した場合（ステップＳ１４の判断結果が「ＮＯ」の場合）には、図２に示すフローチャートの処理が終了する。尚、この場合には、発電施設２０ａで生じた異常によって不足する電力の分だけインバランスが発生することとなる。 On the other hand, if it is determined that the amount of power generation cannot be adjusted at other licensed power generation facilities (power generation facilities 20b, 20c) (when the determination result in step S12 is "NO"), the unlicensed power generation facility (power generation). The aggregator 30 determines whether or not the facility 10) has a margin of power generation enough to reverse the current flow (step S14). When it is determined that there is not enough power generation margin for the unlicensed power generation facility (power generation facility 10) to reverse power flow (when the determination result in step S14 is "NO"), the processing of the flowchart shown in FIG. 2 ends. .. In this case, imbalance will occur by the amount of power shortage due to the abnormality generated in the power generation facility 20a.

これに対し、無認可発電施設（発電施設１０）に逆潮流するだけの発電量の余裕があると判断した場合（ステップＳ１４の判断結果が「ＹＥＳ」の場合）には、無認可発電施設（発電施設１０）の発電電力を電力系統ＰＳに逆潮流させる処理が、アグリゲータ３０によって行われる（ステップＳ１５）。このとき、発電施設１０及び発電施設２０ｂ，２０ｃで発電される電力の総和が、発電施設１０，２０ａ〜２０ｃが接続される配電設備の容量を超えないように（或いは、当初計画していた発電量以下になるように）、アグリゲータ３０によって制御される。 On the other hand, when it is determined that the unlicensed power generation facility (power generation facility 10) has a margin of power generation enough to reverse power flow (when the determination result in step S14 is "YES"), the unlicensed power generation facility (power generation facility) The process of reverse-feeding the generated power of 10) to the power system PS is performed by the aggregator 30 (step S15). At this time, the total power generated by the power generation facilities 10 and the power generation facilities 20b and 20c should not exceed the capacity of the distribution facility to which the power generation facilities 10 and 20a to 20c are connected (or the power generation originally planned). It is controlled by the aggregator 30 (to be less than or equal to the amount).

続いて、上記の異常が生じた認可発電施設（発電施設２０ａ）が復帰したか、又は必要な電力（発電施設２０ａで生じた異常によって不足する電力）が他の発電施設（発電施設２０ｂ，２０ｃ）で賄えるようになったか、がアグリゲータ３０によって判断される（ステップＳ１６）。異常が生じた認可発電施設（発電施設２０ａ）が復帰しておらず、且つ必要な電力が他の発電施設（発電施設２０ｂ，２０ｃ）で賄えるようになっていない場合（ステップＳ１６の判断結果が「ＮＯ」の場合には、無認可発電施設（発電施設１０）の発電電力を電力系統ＰＳに逆潮流させる処理が行われる（ステップＳ１５）。 Subsequently, the licensed power generation facility (power generation facility 20a) in which the above abnormality has occurred has been restored, or the required power (power shortage due to the abnormality in the power generation facility 20a) is in another power generation facility (power generation facility 20b, 20c). ) Is determined by the aggregator 30 (step S16). When the licensed power generation facility (power generation facility 20a) in which the abnormality has occurred has not been restored and the required power cannot be covered by other power generation facilities (power generation facilities 20b, 20c) (the determination result in step S16 is In the case of "NO", a process of reverse-feeding the generated power of the unlicensed power generation facility (power generation facility 10) to the power system PS is performed (step S15).

これに対し、異常が生じた認可発電施設（発電施設２０ａ）が復帰した場合、又は必要な電力が他の発電施設（発電施設２０ｂ，２０ｃ）で賄えるようになった場合（ステップＳ１６の判断結果が「ＹＥＳ」の場合）には、無認可発電施設（発電施設１０）の逆潮流を停止させる処理が、アグリゲータ３０によって行われる（ステップＳ１７）。以上にて、図２に示す一連の処理が終了する。 On the other hand, when the licensed power generation facility (power generation facility 20a) in which the abnormality has occurred is restored, or when the required power can be supplied by another power generation facility (power generation facility 20b, 20c) (judgment result in step S16). When is "YES"), the process of stopping the reverse power flow of the unlicensed power generation facility (power generation facility 10) is performed by the aggregator 30 (step S17). This completes the series of processes shown in FIG.

尚、ステップＳ１２とステップＳ１４との間にブラックアウトが発生する可能性を判断する判断ステップを設け、ブラックアウトが発生する可能性があると判断した場合（判断結果が「ＹＥＳ」の場合）には、ステップＳ１４の処理を行わずに、ステップＳ１５の処理を行うようにしても良い。尚、ブラックアウトが発生する可能性が無いと判断した場合（判断結果が「ＮＯ」の場合）には、ステップＳ１４の処理を行うようにすれば良い。 When a determination step for determining the possibility of blackout is provided between step S12 and step S14 and it is determined that blackout may occur (when the determination result is "YES"). May perform the process of step S15 without performing the process of step S14. If it is determined that there is no possibility of blackout occurring (when the determination result is "NO"), the process of step S14 may be performed.

以上の通り、本実施形態では、電力系統ＰＳへの逆潮流の認可を受けている許可発電施設（発電施設２０ａ〜２０ｃの何れか）で電力系統ＰＳへの逆潮流ができなくなる異常が生じた場合に、アグリゲータ３０が、電力系統ＰＳへの逆潮流の認可を受けていない無許可発電施設（発電施設１０）から電力系統ＰＳへの逆潮流を一時的に行わせるようにしている。このため、逆潮流の認可を受けていない発電施設を有効に活用することができる。その結果として、電力不足を回避することができ、インバランス料金を最小限に抑えることができる。 As described above, in the present embodiment, an abnormality has occurred in which the reverse power flow to the power system PS cannot be performed at the licensed power generation facility (any of the power generation facilities 20a to 20c) that has been approved for reverse power flow to the power system PS. In this case, the aggregator 30 temporarily causes reverse power flow to the power system PS from an unauthorized power generation facility (power generation facility 10) that has not been approved for reverse power flow to the power system PS. Therefore, it is possible to effectively utilize a power generation facility that has not been approved for reverse power flow. As a result, power shortages can be avoided and imbalance charges can be minimized.

以上、本発明の一実施形態による電力需給管理システム、電力需給管理装置、及び電力需給管理方法について説明したが、本発明は上記実施形態に制限されず、本発明の範囲内で自由に変更が可能である。例えば、上記実施形態では、１つの無許可発電施設（発電施設１０）と、３つの許可発電施設（発電施設２０ａ〜２０ｃ）とを備える例について説明下が、無許可発電施設及び許可発電施設の数は任意である。 The power supply and demand management system, the power supply and demand management device, and the power supply and demand management method according to the embodiment of the present invention have been described above, but the present invention is not limited to the above embodiment and can be freely changed within the scope of the present invention. It is possible. For example, in the above embodiment, an example including one unauthorized power generation facility (power generation facility 10) and three licensed power generation facilities (power generation facilities 20a to 20c) will be described below for the unauthorized power generation facility and the licensed power generation facility. The number is arbitrary.

無許可発電施設を複数備える場合において、電力系統ＰＳへの逆潮流を行う際には、複数の無許可発電施設から電力系統ＰＳへの逆潮流を同時に行っても良く、予め設定された優先度が高い無許可発電施設から順に電力系統ＰＳへの逆潮流を行っても良い。或いは、無許可発電施設の発電特性に応じて適切な無許可発電施設を選択して電力系統ＰＳへの逆潮流を行っても良い。例えば、無風の昼間は、太陽光発電装置が設けられた無許可発電施設から電力系統ＰＳへの逆潮流を行い、風のある夜間は、風力発電装置が設けられた無許可発電施設から電力系統ＰＳへの逆潮流を行うといった具合である。 When a plurality of unauthorized power generation facilities are provided, when reverse power flow to the power system PS may be performed simultaneously, reverse power flow from the plurality of unauthorized power generation facilities to the power system PS may be performed at the same time, and a preset priority. The reverse power flow to the power system PS may be performed in order from the unauthorized power generation facility having the highest power. Alternatively, an appropriate unlicensed power generation facility may be selected according to the power generation characteristics of the unlicensed power generation facility to perform reverse power flow to the power system PS. For example, during the daytime when there is no wind, reverse power flow is performed from the unauthorized power generation facility equipped with the photovoltaic power generation device to the power system PS, and at night when there is wind, the power system is performed from the unauthorized power generation facility equipped with the wind power generation device. It is like performing reverse power flow to PS.

また、無許可発電施設及び許可発電施設は、再生可能エネルギー発電装置とともに、或いは再生可能エネルギー発電装置に代えて、固体酸化物形燃料電池（ＳＯＦＣ：Solid Oxide Fuel Cell）や蓄電池を備えるものであっても良い。また、上記実施形態では、無許可発電施設及び許可発電施設とは別にアグリゲータ３０が設けられていたが、発電施設及び許可発電施設の何れかにアグリゲータ３０の機能が設けられた構成であっても良い。かかる構成の場合には、アグリゲータ３０の機能が設けられた発電施設がマスターとなり、他の発電施設がスレーブとなって、情報収集及び制御が行われることとなる。 In addition, unlicensed power generation facilities and licensed power generation facilities are equipped with solid oxide fuel cells (SOFCs) and storage batteries together with renewable energy power generation equipment or in place of renewable energy power generation equipment. You may. Further, in the above embodiment, the aggregator 30 is provided separately from the unauthorized power generation facility and the licensed power generation facility, but even if any of the power generation facility and the licensed power generation facility is provided with the function of the aggregator 30. good. In the case of such a configuration, the power generation facility provided with the function of the aggregator 30 becomes the master, and the other power generation facility becomes the slave, and information collection and control are performed.
