Description

エネルギーシステム、管理システム、エネルギーシステムの制御方法、および管理システムの制御方法Energy system, management system, energy system control method, and management system control method
　本発明は、エネルギーの需給調整を実行するエネルギーシステム、管理システム、エネルギーシステムの制御方法、および管理システムの制御方法に関する。 The present invention relates to an energy system, a management system, an energy system control method, and a management system control method that execute energy supply and demand adjustment.
　エネルギーシステム、たとえば、電力システムにおいて、電力の需給バランスが崩れると、周波数や電圧の変動や、停電が発生する虞がある。そこで、電力の需給バランスを維持するために、各種の需給調整が行われている。 In an energy system, for example, an electric power system, when the supply and demand balance of electric power is disrupted, there is a risk of frequency and voltage fluctuations and power outages. Therefore, various supply and demand adjustments are made in order to maintain the power supply and demand balance.
　たとえば、デマンドレスポンスの場合、需要に連動して時間毎に変動する電力料金を設定（電気料金ベースのデマンドレスポンス）したり、電力使用量が逼迫した際に需要家に対して需要の抑制を要請（インセンティブベースのデマンドレスポンス）したりする需給調整が行われている。 For example, in the case of demand response, set a power rate that fluctuates with time in conjunction with demand (electricity-based demand response), or request that consumers suppress demand when power usage is tight Demand and supply adjustments (incentive-based demand response) are being carried out.
　一方、エネルギー管理システムにおいても、各種の需給調整が行われている。たとえば、特許文献１には、ＢＥＭＳにおいて、優先度が予め設定された複数の削減パターンを記憶し、総予測削減量が必要削減量以上となるまで削減パターンの選択を繰り返すことにより、使用削減目標を達成する省エネルギー支援装置が記載されている。ＢＥＭＳは、Ｂｕiｌｄｉｎｇ　Ｅｎｅｒｇｙ　Ｍａｎａｇｅｍｅｎｔ　Ｓｙｓｔｅｍの略である。また、特許文献２には、無駄なエネルギー消費の削減を優先しその効果を考慮した上で、快適性下限やエネルギーコスト上限を遵守する複数の運用計画案を立案し提示するエネルギー管理装置が記載されている。 On the other hand, various supply and demand adjustments are made in the energy management system. For example, Patent Document 1 stores a plurality of reduction patterns with priorities set in BEMS and repeats the selection of reduction patterns until the total predicted reduction amount is equal to or greater than the necessary reduction amount, thereby reducing the use reduction target. An energy saving support device that achieves the above is described. BEMS is an abbreviation for Building Energy Management System. Patent Document 2 describes an energy management device that prioritizes reduction of useless energy consumption and considers its effects, and then drafts and presents a plurality of operation plans that comply with the comfort lower limit and the energy cost upper limit. Has been.
　特許文献３には、複数の機器稼働パターン候補の中から、最も評価結果の良い一つの機器稼働パターン候補を選択する技術が記載されている。 Patent Document 3 describes a technique for selecting one device operation pattern candidate having the best evaluation result from among a plurality of device operation pattern candidates.
　特許文献４には、所定エリアの１日の電力推移を示す消費電力推移パターンを求めることが記載されている。 Patent Document 4 describes obtaining a power consumption transition pattern indicating a daily power transition in a predetermined area.

　一般的に、上述したような一般的なデマンドレスポンスにおける需給調整、および、特許文献１～３のような一般的なエネルギー管理システムにおける需給調整は、所定長の時間帯（たとえば、１時間）単位で行われている。従って、需給調整の効果は、どうしても限定されてしまう。 In general, the supply and demand adjustment in the general demand response as described above and the supply and demand adjustment in the general energy management system such as Patent Documents 1 to 3 are performed in units of a predetermined time period (for example, 1 hour). It is done in Therefore, the effect of supply and demand adjustment is inevitably limited.
　一方、近年の蓄電技術の進歩により、蓄電設備の容量が増大している。これにより、電力消費の時期を電力供給の時期に束縛されることなく設定することができるようになった。このことは、時間帯を跨いだ需給調整が行える環境が整ったことを意味する。また、蓄電設備がなくとも、適切な情報が与えられるのであれば、需要家の電力消費行動を変化させることができ、結果として時間帯を跨いだ需給調整が可能となる。 On the other hand, due to recent advances in power storage technology, the capacity of power storage facilities is increasing. As a result, the power consumption time can be set without being restricted by the power supply time. This means that an environment in which supply and demand can be adjusted across time zones has been prepared. Moreover, even if there is no power storage facility, if appropriate information is given, the consumer's power consumption behavior can be changed, and as a result, supply and demand can be adjusted across time zones.
　すなわち、近年、時間帯を跨いだ需給調整のニーズがますます高まっている。そして、そのような需給調整を実施するための環境も整いつつある。 That is, in recent years, the need for supply and demand adjustment across time zones is increasing. And the environment for carrying out such supply and demand adjustment is being prepared.
　しかしながら、ある需要を別の時間帯に移動できるかどうかを判断する場合、需給調整者と複数の需要家との間における幾度に亘る情報の授受、および極めて複雑な計算が必要となる。さらに、計算量が膨大となるため、需給調整を短時間で実行することも困難となる。 However, when it is determined whether a certain demand can be moved to another time zone, it is necessary to exchange information between the supply / demand adjuster and a plurality of consumers, and to perform extremely complicated calculations. Furthermore, since the amount of calculation becomes enormous, it is difficult to execute supply and demand adjustment in a short time.
　また、時間帯を跨いだ需給調整を行う場合、需給調整者は、どの時間帯に需要を移動するかを判断するための情報を把握していなければならない。しかしながら、上記情報は、通常、たとえば、生産工程、ワークフロー、生活スタイルなど、本来露出したくない企業や個人の重要情報である。すなわち、上記一般的な需給調整は、重要情報が流失するリスクを有している。 In addition, when performing supply and demand adjustment across time zones, the supply and demand adjuster must grasp information for determining in which time zone the demand moves. However, the information is usually important information of companies and individuals that are not originally exposed, such as production processes, workflows, and lifestyles. That is, the general supply and demand adjustment has a risk that important information will be lost.
　なお、特許文献４には、１日の電力推移を示す消費電力推移パターンが記載されている。しかしながら、特許文献４の技術自体は、単独の家庭における家電機器の消費電力を制御する技術であり、複数の需要家間での需給調整を行う技術ではないため、上記課題を解決することはできない。 Note that Patent Document 4 describes a power consumption transition pattern indicating a daily power transition. However, since the technique itself of Patent Document 4 is a technique for controlling the power consumption of household electrical appliances in a single home and is not a technique for adjusting supply and demand among a plurality of consumers, the above problem cannot be solved. .
　本発明は、上記課題を解決するためになされたものであり、時間帯を跨いだ需給調整を、需要家にとって重要な情報を露出させることなく、容易に実行することができるエネルギーシステム、管理システム、エネルギーシステムの制御方法、および管理システムの制御方法を提供することにある。 The present invention has been made to solve the above-described problems, and an energy system and a management system that can easily execute supply and demand adjustment across time zones without exposing information important to consumers. Another object of the present invention is to provide an energy system control method and a management system control method.
　本発明のエネルギーシステムは、エネルギーを消費する複数の管理対象を含むエネルギーシステムであって、前記複数の管理対象毎に複数のエネルギー消費計画を作成する計画作成手段と、前記複数の管理対象の前記複数のエネルギー消費計画に基づいて、前記複数の管理対象毎に１つのエネルギー消費計画を決定する計画決定手段と、前記複数の管理対象毎の前記１つのエネルギー消費計画に基づいて前記複数の管理対象のそれぞれを運用する運用手段と、を備え、前記エネルギー消費計画は、複数の時間帯を含む所定の期間の消費エネルギーパターンであることを特徴とする。 The energy system of the present invention is an energy system including a plurality of management objects that consume energy, and a plan creation unit that creates a plurality of energy consumption plans for each of the plurality of management objects, and the plurality of management objects Plan determining means for determining one energy consumption plan for each of the plurality of management targets based on a plurality of energy consumption plans, and the plurality of management targets based on the one energy consumption plan for each of the plurality of management targets And the energy consumption plan is an energy consumption pattern of a predetermined period including a plurality of time zones.

［第１の実施形態］
　図１は、本発明の第１の実施形態に係る電力システム５０の構成例を示すブロック図である。電力システム５０は、複数の管理対象１－１～１－ｎ（ｎは、自然数）と、管理システム１０と、を備える。 [First Embodiment]
FIG. 1 is a block diagram illustrating a configuration example of a power system 50 according to the first embodiment of the present invention. The power system 50 includes a plurality of management targets 1-1 to 1-n (n is a natural number) and a management system 10.
　管理対象１－１～１－ｎは、それぞれに、複数の設備機器２と、情報取得部３と、運用部４（運用手段）と、計画作成部５（計画作成手段）と、記憶部６と、入力装置７と、通信部８と、を備える。 Each of the management objects 1-1 to 1-n includes a plurality of facility devices 2, an information acquisition unit 3, an operation unit 4 (operation unit), a plan creation unit 5 (plan creation unit), and a storage unit 6. And an input device 7 and a communication unit 8.
　設備機器２は、電力を消費する機器である。設備機器２は、たとえば、一般家庭内の電気機器、あるいは企業内の電気機器である。情報取得部３は、設備機器２の状態を取得する。運用部４は、設備機器２を運用する。計画作成部５は、記憶部６に記憶された情報（たとえば、過去の生産工程、ワークフロー、生活スタイル情報等）、および／または入力装置７から得た情報（たとえば、センサ情報や操作情報）などに基づいて、複数の電力消費計画（詳細については後述）を作成する。計画作成部５は、通信部８を介して、管理システム１０と通信する。計画作成部５は、管理システム１０に対して、作成した複数の電力消費計画を送信するとともに、管理システム１０から、複数の電力消費計画の中から選択された１つの電力消費計画を受信する。 The equipment 2 is a device that consumes power. The facility device 2 is, for example, an electric device in a general household or an electric device in a company. The information acquisition unit 3 acquires the state of the equipment device 2. The operation unit 4 operates the equipment 2. The plan creation unit 5 includes information stored in the storage unit 6 (for example, past production processes, workflows, lifestyle information, etc.) and / or information obtained from the input device 7 (for example, sensor information and operation information), etc. Based on the above, a plurality of power consumption plans (details will be described later) are created. The plan creation unit 5 communicates with the management system 10 via the communication unit 8. The plan creation unit 5 transmits a plurality of created power consumption plans to the management system 10 and receives one power consumption plan selected from the plurality of power consumption plans from the management system 10.
　管理システム１０は、計画決定部１１（計画決定手段）と、記憶部１２と、通信部１３と、を備える。計画決定部１１は、各管理対象１－１～１－ｎからそれぞれの複数の電力消費計画を受信する。計画決定部１１は、以下で説明するように、所定の決定基準に基づいて、管理対象１－１～１－ｎ毎に、複数の電力消費計画の中から所定の１つの電力消費計画を決定する。計画決定部１１は、選択した１つの各電力消費計画を各管理対象１－１～１－ｎへ送信する。管理システム１０において、管理システム１０と各管理対象１－１～１－ｎの通信（たとえば、電力消費計画の授受）は、通信部１３を介して行われる。記憶部１２は、上記選択に必要な情報を記憶する。また、記憶部１２は、各管理対象１－１～１－ｎから受信した、選択前の複数の電力消費計画、あるいは各管理対象１－１～１－ｎへ送信しようとする選択後の１つの電力消費計画を、一時的に保存する機能を有することもできる。 The management system 10 includes a plan determination unit 11 (plan determination unit), a storage unit 12, and a communication unit 13. The plan determination unit 11 receives a plurality of power consumption plans from each of the management objects 1-1 to 1-n.

　図２は、図１に示す管理システム１０の動作例を説明するフローチャートである。なお、説明をより明りょうなものとするために、以下の説明では、管理対象が２つの場合（管理対象１－１、管理対象１－２）を例に挙げる。 FIG. 2 is a flowchart for explaining an operation example of the management system 10 shown in FIG. In order to make the description clearer, in the following description, the case where there are two management objects (management object 1-1, management object 1-2) is taken as an example.
　まず、図２で説明する動作の開始に先立って、管理対象１－１および管理対象１－２において、それぞれに２つずつ電力消費計画が作成されているものとする。 First, it is assumed that, prior to the start of the operation described in FIG. 2, two power consumption plans are created for each of the management objects 1-1 and 1-2.
　図３Ａは、管理対象１－１における第１の電力消費計画Ａ－１を示す図である。図３Ｂは、管理対象１－１における第２の電力消費計画Ａ－２を示す図である。図３Ｃは、管理対象１－２における第１の電力消費計画Ｂ－１を示す図である。図３Ｄは、管理対象１－２における第２の電力消費計画Ｂ－２を示す図である。 FIG. 3A is a diagram showing a first power consumption plan A-1 in the management object 1-1. FIG. 3B is a diagram showing a second power consumption plan A-2 in the management object 1-1. FIG. 3C is a diagram showing a first power consumption plan B-1 in the management object 1-2. FIG. 3D is a diagram showing a second power consumption plan B-2 in the management object 1-2.
　各々の電力消費計画Ａ－１、Ａ－２、Ｂ－１、Ｂ－２は、いずれも、複数の時間帯（たとえば、１時間）を含む所定の期間（たとえば、１日）についての電力消費計画である。 Each of the power consumption plans A-1, A-2, B-1, and B-2 has a power consumption for a predetermined period (for example, one day) including a plurality of time zones (for example, one hour). It is a plan.
　なお、時間帯と期間について、２以上の時間帯が期間内に含まれる関係が成立していれば十分であり、時間帯および期間の各長さ自体はあくまで任意である。また、複数の時間帯同士は、必ずしも同一長である必要はない。 It should be noted that it is sufficient for the time zone and period to have a relationship in which two or more time zones are included in the period, and the length of each time zone and period itself is arbitrary. Further, the plurality of time zones do not necessarily have the same length.
　また、各々の電力消費計画Ａ－１、Ａ－２、Ｂ－１、Ｂ－２は、いずれも、時間変更できない消費電力と、時間変更が可能な消費電力と、予備電力と、から構成される。 Each of the power consumption plans A-1, A-2, B-1, and B-2 is composed of power consumption that cannot be changed in time, power consumption that can be changed in time, and reserve power. The
　なお、予備電力については、各管理対象の電力消費計画に含めずに管理対象システム１０側で管理するようにしてもよい。 Note that the reserve power may be managed on the management target system 10 side without being included in the power consumption plan of each management target.
　また、電力消費計画Ａ－１、Ａ－２、Ｂ－１、Ｂ－２の総消費電力は等しいことを前提としているが、必ずしも等しくなくてもよい。 In addition, although it is assumed that the total power consumption of the power consumption plans A-1, A-2, B-1, and B-2 is equal, it is not necessarily equal.
　図２の説明に戻る。まず、管理システム１０の計画決定部１１は、管理対象１－１から２つの電力消費計画Ａ－１、Ａ－２を収集するとともに、管理対象１－２から２つの電力消費計画Ｂ－１、Ｂ－２を収集する（ステップＳ１０）。 Returning to the explanation of FIG. First, the plan determination unit 11 of the management system 10 collects two power consumption plans A-1 and A-2 from the management target 1-1, and two power consumption plans B-1 from the management target 1-2. B-2 is collected (step S10).
　計画決定部１１は、収集した電力消費計画から、総消費電力（管理システム１０が管理する全ての管理対象が消費する電力の合計）の計算を行う（ステップＳ１１）。上述したように、本実施形態の場合、２つの管理対象がそれぞれに２つの電力消費計画を作成するケースが想定されている。従って、総消費電力の組み合わせは、図４に示すように、Ｏ、Ｐ、Ｑ、Ｒの計４種類となる。 The plan determination unit 11 calculates the total power consumption (the total power consumed by all management targets managed by the management system 10) from the collected power consumption plan (step S11). As described above, in the present embodiment, a case is assumed in which two management targets create two power consumption plans respectively. Therefore, there are a total of four types of combinations of O, P, Q, and R as shown in FIG.
　図４において“実線”で示される総消費電力Ｏは、電力消費計画Ａ－１と電力消費計画Ｂ－１を加算したものである。図４において“鎖線”で示される総消費電力Ｐは、電力消費計画Ａ－１と電力消費計画Ｂ－２を加算したものである。図４において“一点鎖線”で示される総消費電力Ｑは、電力消費計画Ａ－２と電力消費計画Ｂ－１を加算したものである。図４において“二点鎖線”で示される総消費電力Ｒは、電力消費計画Ａ－２と電力消費計画Ｂ－２を加算したものである。 The total power consumption O indicated by the “solid line” in FIG. 4 is the sum of the power consumption plan A-1 and the power consumption plan B-1. The total power consumption P indicated by “chain line” in FIG. 4 is obtained by adding the power consumption plan A-1 and the power consumption plan B-2. In FIG. 4, the total power consumption Q indicated by “one-dot chain line” is obtained by adding the power consumption plan A-2 and the power consumption plan B-1. The total power consumption R indicated by “two-dot chain line” in FIG. 4 is obtained by adding the power consumption plan A-2 and the power consumption plan B-2.
　計画決定部１１は、所定の決定基準に基づいて、管理対象１－１、１－２毎に、複数の電力消費計画の中から所定の１つの電力消費計画を決定する（ステップＳ１２）。具体的には、上記決定基準が、たとえば、「総消費電力のピークが最も低くなるように電力消費計画を決定する基準」である場合、計画決定部１１は、総消費電力Ｏ、Ｐ、Ｑ、Ｒの中からピークが最も低くなる総消費電力を選択する。この場合、図４に示されるように、ピークが最も低くなるのは、総消費電力Ｑである。そして、上述したように、総消費電力Ｑは、電力消費計画Ａ－２と電力消費計画Ｂ－１を加算したものである。従って、計画決定部１１は、管理対象１－１の電力消費計画を電力消費計画Ａ－２に決定し、管理対象１－２の電力消費計画を電力消費計画Ｂ－１に決定する。 The plan deciding unit 11 decides one predetermined power consumption plan from among a plurality of power consumption plans for each of the management objects 1-1 and 1-2 based on a predetermined determination criterion (Step S12). Specifically, when the determination criterion is, for example, “a criterion for determining a power consumption plan so that the peak of total power consumption is the lowest”, the plan determination unit 11 determines the total power consumption O, P, Q. , R, the total power consumption with the lowest peak is selected. In this case, as shown in FIG. 4, the total power consumption Q has the lowest peak. As described above, the total power consumption Q is obtained by adding the power consumption plan A-2 and the power consumption plan B-1. Therefore, the plan determination unit 11 determines the power consumption plan of the management target 1-1 as the power consumption plan A-2, and determines the power consumption plan of the management target 1-2 as the power consumption plan B-1.
　計画決定部１１は、決定した各電力消費計画を各々の管理対象に通知する（ステップＳ１３）。 The plan determination unit 11 notifies each management target of each determined power consumption plan (step S13).
　以上説明した第１の実施形態では、時間変更が可能な電力需要があるものの、生産工程、ワークフロー、生活スタイル等によって、消費電力の量や順序、時間の推移などのルールに束縛される場合であっても、各管理対象は、時間帯を跨いだ電力消費計画を選択することができる。すなわち、本実施形態は、単純にある時間帯内の消費のみを抑えるのではなく、管理対象ごとのルール（需要家が受け入れ可能な電力消費計画）を考慮して、所定の期間（たとえば、１日）の総電力消費量を削減することができる。 In the first embodiment described above, although there is a power demand that can be changed in time, it is bound by rules such as the amount and order of power consumption and the transition of time depending on the production process, workflow, lifestyle, etc. Even if it exists, each management object can select the power consumption plan across time zones. That is, the present embodiment does not simply suppress consumption within a certain time period, but considers a rule for each management target (a power consumption plan that can be accepted by a consumer), for a predetermined period (for example, 1 Day) total power consumption can be reduced.
　さらに、本実施形態の場合、複数の電力消費計画を作成し、複数の電力消費計画の中から１つの計画を選択するといった極めてシンプルな処理にて需給調整を行うことができる。従って、需要を別の時間帯に移動できるかどうかを判断するための情報を複数の需要家との間で幾度となく繰り返す処理は、不要となる。すなわち、本実施形態によれば、時間帯を跨いだ需給調整を容易に実行することができる。もちろん、計算処理がシンプルであるため、需給調整に費やされる時間自体も短縮される。 Furthermore, in the case of the present embodiment, supply and demand can be adjusted by an extremely simple process of creating a plurality of power consumption plans and selecting one plan from the plurality of power consumption plans. Therefore, it is unnecessary to repeat the information for determining whether or not the demand can be moved to another time zone with a plurality of consumers. That is, according to the present embodiment, it is possible to easily execute supply and demand adjustment across time zones. Of course, since the calculation process is simple, the time itself required for supply and demand adjustment is shortened.
　さらに、本実施形態の場合、各管理対象から管理システム１０へ送信される情報は、生の重要情報（たとえば、生産工程、ワークフロー、生活スタイルなど、本来露出したくない企業や個人の情報）ではなく、重要情報に基づいて作成された電力消費計画である。電力消費計画自体は、公開しても特に差し支えの無い情報であり、少なくとも重要情報と比較すれば、流失した際のリスクは極めて小さい。従って、各管理対象の管理者と管理システム１０の管理者とが異なるようなケースであっても、少なくとも重要情報の直接的な流失は回避される。 Furthermore, in the case of the present embodiment, information transmitted from each management target to the management system 10 is raw important information (for example, information on companies and individuals that are not originally exposed such as production processes, workflows, lifestyles, etc.). It is a power consumption plan created based on important information. The power consumption plan itself is information that can be safely disclosed, and at least compared with important information, the risk of being lost is extremely small. Therefore, even if the manager of each management target and the manager of the management system 10 are different, at least direct loss of important information is avoided.
　以上を纏めると、本実施形態によれば、時間帯を跨いだ需給調整を、需要家にとって重要な情報を露出させることなく、容易に実行することができる。 Summarizing the above, according to the present embodiment, it is possible to easily execute supply and demand adjustment across time zones without exposing information important to consumers.
　さらに、本実施形態において、複数の電力消費計画は、各管理対象側にて作成される。換言すれば、複数の電力消費計画は、各管理対象によって同意された計画である。そして、各管理対象は、上記複数の電力消費計画の中から選択された所定の１つの電力消費計画に基づいて運用される。すなわち、最終的にどの電力消費計画が選択された場合であっても、運用に用いられる計画は、必ず、管理対象側が意図した計画となる。従って、選択された計画への不満に基づく計画のやり直しが発生することもない。さらに、意図と異なる計画を甘んじて受け入れることによる各管理対象側の利便性の低下も発生しない。 Furthermore, in this embodiment, a plurality of power consumption plans are created on each management target side. In other words, the plurality of power consumption plans are plans agreed by each management target. Each management target is operated based on one predetermined power consumption plan selected from the plurality of power consumption plans. That is, regardless of which power consumption plan is finally selected, the plan used for operation is always the plan intended by the management target side. Therefore, the redo of the plan based on the dissatisfaction with the selected plan does not occur. Furthermore, there is no decrease in convenience for each management target by accepting a plan different from the intention.
　さらに、本実施形態において、電力消費計画は、時間変更できない消費電力と、時間変更が可能な消費電力とから構成される。従って、総消費量を計算するときに、時間変更できない消費電力と、時間変更が可能な消費電力とに分離して計算するとことにより、計算量を削減できるメリットがある。 Furthermore, in the present embodiment, the power consumption plan includes power consumption that cannot be changed in time and power consumption that can be changed in time. Therefore, when calculating the total consumption, the calculation amount can be reduced by separately calculating the power consumption that cannot be changed in time and the power consumption that can be changed in time.
　なお、以上説明した第１の実施形態では、２つの管理対象１－１および管理対象１－２において、それぞれに２つずつ電力消費計画が作成されている場合を例に挙げたが、管理対象の数および電力消費計画の数が上記各数に限定されないことは説明するまでもない。 In the first embodiment described above, the case where two power consumption plans are created for each of the two management objects 1-1 and 1-2 is described as an example. It goes without saying that the number of power consumption and the number of power consumption plans are not limited to the above numbers.
　また、以上説明した第１の実施形態では、１つの電力消費計画を決定する基準である決定基準を「総消費電力のピークが最も低くなるように電力消費計画を決定する基準」とする場合を例に挙げたが、これはあくまで一例であり、決定基準は上記に限定されない。
［第２の実施形態］
　本実施形態は、管理対象１－１～１－ｎを管理している管理者が、管理システム１０を管理している管理者（たとえば、アグリゲータ）と異なる事業体であり、且つ電力消費計画にインセンティブ（あるいはペナルティ）を付与する場合を想定している。構成自体は、第１の実施形態と同一である。 Further, in the first embodiment described above, a case where the determination criterion, which is a criterion for determining one power consumption plan, is “a criterion for determining a power consumption plan so that the peak of the total power consumption is the lowest”. Although given as an example, this is merely an example, and the determination criterion is not limited to the above.
[Second Embodiment]
In the present embodiment, the administrator who manages the management objects 1-1 to 1-n is a different business entity from the administrator who manages the management system 10 (for example, an aggregator), and is included in the power consumption plan. It is assumed that an incentive (or penalty) is given. The configuration itself is the same as that of the first embodiment.
　図５は、第２の実施形態に係る管理システム１０の動作例を説明するフローチャートである。なお、説明をより明りょうなものとするために、以下の説明では、管理対象が２つの場合（管理対象１－１、管理対象１－２）を例に挙げる。 FIG. 5 is a flowchart for explaining an operation example of the management system 10 according to the second embodiment. In order to make the description clearer, in the following description, the case where there are two management objects (management object 1-1, management object 1-2) is taken as an example.
　まず、図５で示す動作の開始に先立って、各管理対象１－１、１－２は、予め、各管理対象１－１、１－２を管理する管理者から、優先順位とインセンティブとの関係を示した優先順位リスト（図６参照）を通知される。 First, prior to the start of the operation shown in FIG. 5, each of the management targets 1-1 and 1-2 is preliminarily assigned by the administrator who manages each of the management targets 1-1 and 1-2. A priority list (see FIG. 6) indicating the relationship is notified.
　各管理対象１－１、１－２を管理する事業体は、上記情報に基づいて、複数の電力消費計画（図７参照）を作成する。この場合、策定する計画の数は、管理対象毎に異なっていてもよく、異なった電力消費計画に同一の優先順位を付加してもよい。また、必ずしも、全ての優先順位が付加されなくてもよい。ただし、優先順位１（インセンティブがない）の計画は、必ず含まれるものとする。なお、電力消費計画にかかる優先順位以外の内容は、第１の実施形態と同様である。 The business entity that manages each of the management objects 1-1 and 1-2 creates a plurality of power consumption plans (see FIG. 7) based on the above information. In this case, the number of plans to be formulated may be different for each management target, and the same priority may be added to different power consumption plans. Also, not all priorities need to be added. However, a plan with priority 1 (no incentive) is always included. The contents other than the priority order related to the power consumption plan are the same as those in the first embodiment.
　図５の説明に戻る。まず、管理システム１０の計画決定部１１は、各管理対象１－１、１－２のそれぞれから複数の電力消費計画を収集する（ステップＳ２０）。 Returning to the explanation of FIG. First, the plan determination unit 11 of the management system 10 collects a plurality of power consumption plans from each of the management objects 1-1 and 1-2 (step S20).
　計画決定部１１は、収集した電力消費計画のうち、優先順位１のものを集めて、総消費電力の計算を行う（ステップＳ２１）。計画決定部１１は、所定の上限値（たとえば、予め定められた目標や供給制限で決定される上限値）を超過する総消費電力の有無を判定する（ステップＳ２２）。 The plan determination unit 11 collects the power consumption plans collected in the priority order 1 and calculates the total power consumption (step S21). The plan determining unit 11 determines whether or not there is total power consumption exceeding a predetermined upper limit value (for example, an upper limit value determined by a predetermined target or supply limit) (step S22).
　上限値を超過する総消費電力が存在した場合（ステップＳ２２においてＹｅｓ判定）、計画決定部１１は、インセンティブの計算を行う（ステップＳ２３）。この場合、計画決定部１１は、たとえば、優先順位に対応した単価に、時間変更が可能な電力を乗じた値をインセンティブとする。 When there is total power consumption exceeding the upper limit value (Yes in step S22), the plan determination unit 11 calculates an incentive (step S23). In this case, for example, the plan determination unit 11 uses the value obtained by multiplying the unit price corresponding to the priority order by the power that can be changed in time as an incentive.
　計画決定部１１は、管理対象１－１、１－２毎に、複数の電力消費計画の中から所定の１つの電力消費計画を決定する（ステップＳ２４）。具体的には、計画判定部１１は、上限値以下となる電力消費計画の組み合わせのうち最もインセンティブの総和が低いものを、電力消費計画として決定する。 The plan determination unit 11 determines a predetermined one power consumption plan from among a plurality of power consumption plans for each of the management objects 1-1 and 1-2 (step S24). Specifically, the plan determination unit 11 determines a power consumption plan that has the lowest sum of incentives among combinations of power consumption plans that are equal to or lower than the upper limit value.
　計画選択部１１は、決定された各電力消費計画を各々の管理対象に通知する（ステップＳ２５）。 The plan selection unit 11 notifies each management target of each determined power consumption plan (step S25).
　以上説明した第２の実施形態によれば、第１の実施形態と同様の効果を得ることができる。 According to the second embodiment described above, the same effect as that of the first embodiment can be obtained.
　さらに、以上説明した第２の実施形態によれば、各管理対象自らが計画し提出した電力消費計画が採用され、かつ各管理対象がインセンティブによって優先順位の低い電力消費計画を受け容れる仕組み、すなわち、各管理対象が需給調整に能動的に関与する仕組みが提供される。 Furthermore, according to the second embodiment described above, a power consumption plan planned and submitted by each managed object is adopted, and each managed object accepts a low-priority power consumption plan by incentive, that is, A mechanism in which each management target is actively involved in supply and demand adjustment is provided.
　なお、上限値に収まる電力消費計画の組み合わせが存在しない場合（ステップＳ２３）、ベストな電力消費計画を選択した上で、通常のアグリゲータが実行する対応（たとえば、特定の管理対象に対して特別な節電の要請をする、あるいは、上位の供給元に対して供給を増やすように要請する等）を行うことができる。 If there is no combination of power consumption plans that falls within the upper limit (step S23), the best power consumption plan is selected, and then a response that a normal aggregator performs (for example, a special management target has a special Requesting power saving, or requesting higher-order suppliers to increase supply).
　また、アグリゲータにより仮想的にグルーピングすることや、需給調整への協力度合い、グルーピングの規模などによりインセンティブの代わりに料金体系を変えることも可能である。 In addition, it is possible to virtually group with an aggregator, change the fee structure instead of incentives depending on the degree of cooperation in supply and demand adjustment, the scale of grouping, etc.
　なお、以上説明した第１および第２の実施形態では、「需要＝消費量」を前提とした説明を行った。しかしながら、必ずしも需要と消費量はイコールである必要はない。たとえば、蓄電設備があれば、あらかじめ蓄電設備に充電し、消費する時間を別に移すことも可能である。その場合、複数の電力消費計画に、蓄電設備への充放電計画を繰り込むようにすればよい。 In the first and second embodiments described above, the description has been made on the assumption that “demand = consumption”. However, demand and consumption are not necessarily equal. For example, if there is a power storage facility, it is possible to charge the power storage facility in advance and shift the consumption time separately.
