(Embodiment)
FIG. 1 shows a schematic block diagram of the present embodiment. First, an outline of the storage control system 1 of the present embodiment will be described.

本実施形態の蓄電制御システム１は、蓄電池２１を有し戸建住宅６（需要家施設）に設けられる蓄電装置２、を制御するシステムであり、蓄電制御部３１と計画制御部４１１（第１制御部）と割込制御部４１２（第２制御部）とを備える。蓄電制御部３１は、蓄電装置２の動作を制御する。計画制御部４１１は、対象期間における蓄電装置２の動作指示内容を示す計画制御指示（第１制御指示）を、蓄電制御部３１に出力する。割込制御部４１２は、蓄電装置２の動作指示内容を示す割込制御指示（第２制御指示）を、蓄電制御部３１に出力する。そして、蓄電制御部３１は、対象期間において計画制御部４１１から受け取った計画制御指示に基づいて蓄電装置２の動作を制御し、対象期間中に割込制御部４１２から割込制御指示を受け取った場合、第２制御指示に基づいて蓄電装置２の動作を制御する。   The storage control system 1 of the present embodiment is a system for controlling the storage device 2 having a storage battery 21 and provided in a detached house 6 (customer facility), and includes a storage control unit 31 and a plan control unit 411 (first Control unit) and an interrupt control unit 412 (second control unit).

When the storage control unit 31 receives the interrupt control instruction, the storage control unit 31 controls the operation of the storage device 2 based on the interrupt control instruction with priority over the plan control instruction. Therefore, it is possible to improve the responsiveness from the request for power adjustment to the control of the operation of power storage device 2.

以下に、本実施形態の蓄電制御システム１について詳細に説明する。本実施形態の蓄電制御システム１は、蓄電制御部３１を有する蓄電制御装置３と、計画制御部４１１及び割込制御部４１２を有する指示制御装置４１とを備えて構成されている。なお、本実施形態では、需要家施設として戸建住宅６を例に説明するが、需要家施設は集合住宅や事業所などであってもよい。   Below, the electrical storage control system 1 of this embodiment is demonstrated in detail. The storage control system 1 of the present embodiment is configured to include a storage control device 3 having a storage control unit 31, and an instruction control device 41 having a plan control unit 411 and an interruption control unit 412. In the present embodiment, although the detached house 6 is described as an example of the consumer facility, the consumer facility may be an apartment complex, a business establishment, or the like.

戸建住宅６は、電気負荷６１（例えば照明器具、空調装置、冷蔵庫など）に電力を供給する電源として、商用電源７と蓄電装置２と発電装置８とを用いている。商用電源７は、電力系統７１、及び電力メータ６２を介して戸建住宅６に設けられた分電盤６３に電気的に接続されており、交流電力（商用電力）を分電盤６３に供給する。また、発電装置８は、例えば太陽光発電装置であり、太陽電池モジュール８１と電力変換部８２とを備えている。太陽電池モジュール８１は、戸建住宅６の屋根などに設けられ、太陽光を受光することによって発電する。電力変換部８２は、太陽電池モジュール８１によって発電された直流電力を交流電力に変換して分電盤６３に供給する。なお、発電装置８は、太陽光発電装置に限らず、例えば燃料電池を備えた燃料電池発電装置であってよい。また、発電装置８として、太陽光発電装置と燃料電池発電装置とが併用されていてもよい。蓄電装置２は、蓄電池２１と電力変換部２２とを備えている。蓄電池２１は、充電及び放電が可能に構成されている。電力変換部２２は、蓄電池２１が放電した直流電力を交流電力に変換して分電盤６３に供給する。また、電力変換部２２は、分電盤６３から供給される交流電力を直流電力に変換して蓄電池２１を充電する。分電盤６３の盤内には、主幹ブレーカ及び複数の分岐ブレーカなどが内蔵されており、複数の分岐ブレーカの各々に接続された分岐回路を介して交流電力が電気負荷６１に供給される。また、太陽電池モジュール８１によって発電された直流電力は、電力変換部８２で交流電力に変換し電力系統７１に逆潮流させて売電することができる。   The detached house 6 uses a commercial power supply 7, a storage device 2 and a power generation device 8 as a power supply for supplying electric power to an electric load 61 (for example, a lighting fixture, an air conditioner, a refrigerator, etc.). Commercial power supply 7 is electrically connected to distribution board 63 provided in detached house 6 through power system 71 and power meter 62, and supplies AC power (commercial power) to distribution board 63. Do. The power generation device 8 is, for example, a solar power generation device, and includes a solar cell module 81 and a power conversion unit 82. The solar cell module 81 is provided on the roof or the like of the detached house 6, and generates electric power by receiving sunlight. The power conversion unit 82 converts the DC power generated by the solar cell module 81 into AC power and supplies the AC power to the distribution board 63. The power generation device 8 is not limited to the solar power generation device, and may be, for example, a fuel cell power generation device provided with a fuel cell. Moreover, as the power generation device 8, a solar power generation device and a fuel cell power generation device may be used in combination. Power storage device 2 includes storage battery 21 and power conversion unit 22. The storage battery 21 is configured to be capable of charging and discharging. Power converter 22 converts the DC power discharged from storage battery 21 into AC power and supplies the AC power to distribution board 63. Further, the power conversion unit 22 converts alternating current power supplied from the distribution board 63 into direct current power to charge the storage battery 21. A master breaker, a plurality of branch breakers, and the like are built in the panel of the distribution board 63, and AC power is supplied to the electric load 61 via the branch circuits connected to each of the plurality of branch breakers. Further, DC power generated by the solar cell module 81 can be converted into AC power by the power conversion unit 82 and can be reversely flowed to the power system 71 to be sold.

蓄電装置２における蓄電池２１の充放電動作は、戸建住宅６に設けられた蓄電制御装置３によって制御される。蓄電装置２と蓄電制御装置３とは、例えば信号線を介した有線通信、または無線信号を媒体とした無線通信などによって互いに通信可能に構成されている。蓄電制御装置３は、蓄電装置２の電力変換部２２を制御することで、蓄電装置２における蓄電池２１の充放電動作を制御する。また、蓄電制御装置３は、指示制御装置４１から出力される計画制御指示あるいは割込制御指示に基づいて、蓄電装置２に対する充放電動作の指示内容を決定する。   The charge and discharge operation of the storage battery 21 in the storage device 2 is controlled by the storage control device 3 provided in the detached house 6. The storage device 2 and the storage control device 3 are configured to be able to communicate with each other, for example, by wired communication via a signal line, or wireless communication using a wireless signal as a medium. The storage control device 3 controls the charge conversion operation of the storage battery 21 in the storage device 2 by controlling the power conversion unit 22 of the storage device 2. Further, the storage control device 3 determines the content of the charge / discharge operation instruction for the storage device 2 based on the plan control instruction or the interrupt control instruction output from the instruction control device 41.

近年、電力事業者などによって、電力需給を調整するためにデマンドレスポンス（Demand Response）を用いたサービスが提案されている。デマンドレスポンス技術の１つとして、需要家施設に蓄電装置２、あるいは蓄電装置２と発電装置８を導入し、時間帯別の電気料金を活用することで、電力ピークを抑制する手法が提案されている。例えば、電力ピークを抑制したい時間帯の電気料金を高く設定し、蓄電装置２の蓄電池２１の放電を促すことにより、顧客の電気料金の総額が削減される。エネルギー供給者である電力事業者は、電力ピークが抑制されることで、電力の調達コストが削減される。   BACKGROUND In recent years, services using demand response have been proposed by power companies and the like to adjust power supply and demand. As one of the demand response technology, a method is proposed to suppress the power peak by introducing the power storage device 2 or the power storage device 2 and the power generation device 8 to the customer's facility and utilizing the electricity charges by time zone. There is. For example, by setting the electricity rate of the time zone in which the power peak is to be suppressed high, and promoting the discharge of the storage battery 21 of the power storage device 2, the total electricity rate of the customer is reduced. The power supplier, who is an energy supplier, can reduce the power procurement cost by suppressing the power peak.

また、顧客にとって電気料金の削減には、蓄電池２１の充放電（充電及び放電）のタイミングを最適化することが重要である。例えば、電気料金だけでなく、過去の電力消費実績量、カレンダ情報、顧客の電力契約、蓄電池２１の状態、天気予報などの各種情報、あるいは各種情報の予測結果を基に、蓄電池２１の充放電タイミングを最適化するものであってもよい。上記の各種情報及び各種情報の予測には、膨大なデータ量や複雑な演算が必要となるため、需要家施設に設けられた端末（装置）で演算を行うのではなく、例えばクラウドなどのサーバを活用するものであってもよい。クラウドのサーバを用いて蓄電池２１の充放電タイミングを計画することによって、上記の各種情報を有効活用し、需要家施設間または系統といったマクロ視点での電力需給の変動に対応することができる。また、サーバが複数の需要家施設に対応して蓄電池２１の充放電タイミングを計画するので、計算機資源が共有化され、コストの削減を図ることができる。   Further, it is important for the customer to optimize the timing of charge and discharge (charge and discharge) of the storage battery 21 in order to reduce the electricity rate. For example, charging / discharging of the storage battery 21 is based not only on the electricity charges but also on the past amount of power consumption, calendar information, customer's power contract, status of the storage battery 21, various information such as weather forecast, or prediction result of various information. The timing may be optimized. Since the prediction of the above various information and various information requires a huge amount of data and complicated calculations, it is not necessary to carry out the calculations with a terminal (apparatus) provided at the customer facility, but for example a server such as a cloud May be used. By planning the charge / discharge timing of the storage battery 21 using a cloud server, the various information described above can be effectively used to cope with fluctuations in the power supply and demand from a macro viewpoint such as between customer facilities or a system. In addition, since the server plans the charge / discharge timing of the storage battery 21 corresponding to a plurality of customer facilities, computer resources can be shared, and costs can be reduced.

また、電力事業者は、需要家施設に設けられた蓄電装置２を分散電源とみなすことにより、蓄電装置２を電力需要逼迫時の予備電源設備として活用できる。これは、デマンドレスポンス技術の１つであるDLC（Direct Load Control）とみなすことができる。また、市場における電力の調達コストは、例えば５分、３０分といった短時間で変化することが予測される。電力事業者は、高い費用を払って市場から電力を調達せず、需要家施設に設けられた蓄電装置２の蓄電池２１を放電させることで、電力の調達コストを削減することができる。電力事業者は、需要家施設に設けられた蓄電装置２の蓄電池２１の充放電などの顧客に対する電力調整の要請をＤＲ要請として行う。このＤＲ要請には、電力調整を要請する期間（以降、要請期間という）、調整する電力量、蓄電池２１の充電あるいは放電などの動作要請などが含まれる。   In addition, the power company can utilize the storage device 2 as a standby power supply at the time of tight power demand by regarding the storage device 2 provided in the customer facility as the dispersed power source. This can be regarded as DLC (Direct Load Control), which is one of the demand response techniques. In addition, the cost of power supply in the market is expected to change in a short time, such as 5 minutes or 30 minutes. The electric power company can reduce the procurement cost of electric power by discharging the storage battery 21 of the power storage device 2 provided in the customer facility without procuring electric power from the market at high cost. The power company makes a request for power adjustment to the customer such as charge and discharge of the storage battery 21 of the power storage device 2 provided in the customer facility as a DR request. The DR request includes a period for requesting power adjustment (hereinafter referred to as a request period), an amount of power to be adjusted, and an operation request for charging or discharging the storage battery 21 or the like.

本実施形態の蓄電制御システム１は、電力事業者と顧客との間で電力需給のバランスを調整し、戸建住宅６（需要家施設）に設けられた蓄電装置２の蓄電池２１の充放電タイミングを最適化する制御サーバ群４を備えている。制御サーバ群４は、アグリゲータ（aggregator）によって管理されており、複数の指示制御装置４１と複数のデータベース４２とを備えている。複数の指示制御装置４１の各々は、サーバで構成されており、複数の指示制御装置４１と複数のデータベース４２とが互いに連携してクラウドコンピューティングシステムを構成している。   The storage control system 1 of this embodiment adjusts the balance of the power supply and demand between the power company and the customer, and the charge / discharge timing of the storage battery 21 of the storage device 2 provided in the detached house 6 (consumer facility) Control server group 4 that optimizes The control server group 4 is managed by an aggregator, and includes a plurality of instruction control devices 41 and a plurality of databases 42. Each of the plurality of instruction control devices 41 is configured by a server, and the plurality of instruction control devices 41 and the plurality of databases 42 cooperate with each other to configure a cloud computing system.

制御サーバ群４は、戸建住宅６（需要家施設）に設けられた蓄電装置２における蓄電池２１の充放電タイミングが最適となるように、蓄電制御装置３に対して蓄電装置２の動作指示内容を伝達する。具体的には、指示制御装置４１は、計画制御部４１１、割込制御部４１２、及び通信部４１３を備えている。   Control server group 4 instructs the storage control device 3 to operate the storage device 2 so that the charge / discharge timing of the storage battery 21 in the storage device 2 provided in the detached house 6 (consumer facility) becomes optimal. To communicate. Specifically, the instruction control device 41 includes a plan control unit 411, an interrupt control unit 412, and a communication unit 413.

計画制御部４１１は、戸建住宅６（需要家施設）における電力の需給状態、カレンダ情報、顧客の電力契約、蓄電池２１の状態、天気予報などの各種情報に基づいて、蓄電池２１の充放電タイミングが最適となる蓄電池２１の充放電タイミングを演算する。計画制御部４１１は、比較的長期間を対象期間とした蓄電池２１の充放電タイミングを演算して求めており、例えば現在から２４時間分の蓄電池２１の充放電タイミングを演算して求める。そして、計画制御部４１１は、求めた蓄電池２１の充放電タイミングを、蓄電装置２の動作指示内容とした計画制御指示（第１制御指示）を作成する。また、計画制御部４１１は、所定の間隔（例えば３０分、１時間）で計画制御指示を作成、言い換えれば計画制御指示の更新を行っている。計画制御部４１１は、計画制御指示の更新の都度、対象期間（計画制御指示の作成時から２４時間分）における蓄電池２１の充放電タイミングの計画を作成する。これにより、例えば上述した各種情報の予測結果に変化が生じた場合、この変化に応じて最適化された蓄電池２１の充放電タイミングの計画（計画制御指示）を作成することができる。   The plan control unit 411 controls charge and discharge timing of the storage battery 21 based on various information such as supply and demand of power in the detached house 6 (consumer facility), calendar information, power contract of the customer, status of the storage battery 21, and weather forecast. The charging / discharging timing of the storage battery 21 which becomes optimal is calculated. The plan control unit 411 calculates the charge / discharge timing of the storage battery 21 with a relatively long period as the target period, for example, and calculates the charge / discharge timing of the storage battery 21 for 24 hours from the current time. Then, the plan control unit 411 creates a plan control instruction (first control instruction) with the determined charge / discharge timing of the storage battery 21 as the operation instruction content of the power storage device 2. The plan control unit 411 also creates a plan control instruction at predetermined intervals (for example, 30 minutes, 1 hour), in other words, updates the plan control instruction. The plan control unit 411 creates a plan of charge / discharge timing of the storage battery 21 in the target period (for 24 hours from the time of creation of the plan control instruction) each time the plan control instruction is updated. Thereby, for example, when a change occurs in the prediction result of the various information described above, it is possible to create a plan (plan control instruction) of charge / discharge timing of the storage battery 21 optimized according to the change.

割込制御部４１２は、計画制御部４１１が作成した計画制御指示に緊急の修正が必要な事象が発生した場合、この事象に基づいた蓄電池２１の充放電タイミングを、蓄電池２１の動作指示内容とした割込制御指示（第２制御指示）を作成する。なお、割込制御部４１２が割込制御指示を作成するタイミングについては後述する。   When an event requiring urgent correction occurs in the plan control instruction created by the plan control unit 411, the interrupt control unit 412 determines the charge / discharge timing of the storage battery 21 based on this event as the operation instruction content of the storage battery 21. Create an interrupt control instruction (second control instruction). The timing at which the interrupt control unit 412 generates an interrupt control instruction will be described later.

通信部４１３は、通信インターフェースであり、通信回線９（例えばインターネット回線）に接続されている。計画制御部４１１及び割込制御部４１２は、それぞれ、通信部４１３を介して蓄電制御装置３に計画制御指示、割込制御指示を出力する。   The communication unit 413 is a communication interface, and is connected to the communication line 9 (for example, the Internet line). The plan control unit 411 and the interrupt control unit 412 respectively output a plan control instruction and an interrupt control instruction to the storage control device 3 via the communication unit 413.

蓄電制御装置３は、蓄電制御部３１、記憶部３２、通信部３３を備えており、指示制御装置４１から出力される計画制御指示あるいは割込制御指示に基づいて、蓄電装置２における蓄電池２１の充放電を制御する。   The storage control device 3 includes a storage control unit 31, a storage unit 32, and a communication unit 33. The storage control device 3 includes storage batteries 21 in the storage device 2 based on a plan control instruction or an interrupt control instruction output from the instruction control device 41. Control charge and discharge.

通信部３３は、通信インターフェースであり、戸建住宅６に設けられたルータ６４を介して通信回線９に接続されている。そして、通信部３３は、指示制御装置４１から出力される計画制御指示、割込制御指示を、通信回線９及びルータ６４を介して受け取る。   The communication unit 33 is a communication interface, and is connected to the communication line 9 via the router 64 provided in the detached house 6. Then, the communication unit 33 receives the plan control instruction and the interrupt control instruction output from the instruction control device 41 via the communication line 9 and the router 64.

記憶部３２は、通信部３３が受信した計画制御指示及び割込制御指示を記憶する。なお、記憶部３２に記憶される計画制御指示は、通信部３３が計画制御指示を受け取る度に、最新の計画制御指示に更新される。   The storage unit 32 stores the plan control instruction and the interrupt control instruction received by the communication unit 33. The plan control instruction stored in the storage unit 32 is updated to the latest plan control instruction each time the communication unit 33 receives the plan control instruction.

蓄電制御部３１は、記憶部３２に記憶された計画制御指示あるいは割込制御指示を参照し、現在の時刻に対応する蓄電池２１の充放電タイミングに従って、蓄電装置２における蓄電池２１の充放電動作を制御する。蓄電制御部３１は、計画制御指示と割込制御指示とが重複する場合、割込制御指示を優先し、割込制御指示に基づいて蓄電装置２の動作を制御する。   The storage control unit 31 refers to the plan control instruction or the interrupt control instruction stored in the storage unit 32 and performs the charging / discharging operation of the storage battery 21 in the storage device 2 according to the charging / discharging timing of the storage battery 21 corresponding to the current time. Control. When the plan control instruction and the interrupt control instruction overlap, the storage control unit 31 gives priority to the interrupt control instruction, and controls the operation of the storage device 2 based on the interrupt control instruction.

また、指示制御装置４１は、電力事業者のサーバ５から出力されるＤＲ要請の内容を判断する判断部４１４をさらに備えている。判断部４１４は、ＤＲ要請の内容に基づいて、計画制御部４１１に計画制御指示の作成、あるいは割込制御部４１２に割込制御指示の作成を指示する。   Further, the instruction control device 41 further includes a determination unit 414 that determines the content of the DR request output from the server 5 of the power company. The determination unit 414 instructs the plan control unit 411 to create a plan control instruction or to generate an interrupt control instruction to the interrupt control unit 412 based on the contents of the DR request.

具体的には、判断部４１４は、例えばＤＲ要請の内容が、蓄電制御装置３で処理可能な内容であるか否かを判断する。ＤＲ要請の内容が、例えば「所定期間（要請期間）に、蓄電池２１の放電（あるいは充電）を要請する」といった単純な内容で複雑な演算処理が不要である場合、「蓄電制御装置３で処理可能である」と判断する。一方、ＤＲ要請の内容が、例えば「要請期間に、地域内における商用電力の使用量を所定量削減することを要請する」といった複数の需要家施設の蓄電装置２間での連携が必要であるような内容である場合、「蓄電制御装置３での処理が不可である」と判断する。さらに、判断部４１４は、ＤＲ要請が示す要請期間の開始時刻が、計画制御部４１１が次回の計画制御指示の作成タイミングよりも早いか遅いかを判断する。   Specifically, the determination unit 414 determines, for example, whether the content of the DR request is content that can be processed by the storage control device 3 or not. If the contents of the DR request are simple contents such as “requesting discharge (or charge) of the storage battery 21 in a predetermined period (request period)” and complicated arithmetic processing is unnecessary, “Processing by the storage control device 3” It is judged that it is possible. On the other hand, coordination among power storage devices 2 of a plurality of customer facilities is required, for example, “request to reduce the amount of commercial power used in a region by a predetermined amount during a request period”, for example, the content of DR request If the contents are as described above, it is determined that "the processing by the storage control device 3 is not possible". Furthermore, the determination unit 414 determines whether the start time of the request period indicated by the DR request is earlier or later than the creation timing of the next plan control instruction.

そして、判断部４１４は、ＤＲ要請の内容の判断結果に基づいて、計画制御部４１１に計画制御指示の作成、あるいは割込制御部４１２に割込制御指示の作成を指示する。具体的には、判断部４１４は、ＤＲ要請の内容が、蓄電制御装置３で処理可能であり、かつ要請期間の開始時刻が次回の計画制御指示の作成タイミングよりも早い場合、割込制御部４１２に割込制御指示の作成を指示する。この場合、割込制御部４１２は、ＤＲ要請の内容に基づいた割込制御指示を作成し、作成した割込制御指示を蓄電制御装置３に出力する。なお、割込制御部４１２は、ＤＲ要請を割込制御指示として、蓄電制御装置３に出力してもよい。   Then, based on the determination result of the content of the DR request, the determination unit 414 instructs the plan control unit 411 to create a plan control instruction or to generate the interrupt control instruction to the interrupt control unit 412. Specifically, if the content of the DR request can be processed by power storage control device 3 and the start time of the request period is earlier than the creation timing of the next plan control instruction, determination unit 414 determines that the interrupt control unit At 412, generation of an interrupt control instruction is instructed. In this case, the interrupt control unit 412 creates an interrupt control instruction based on the content of the DR request, and outputs the created interrupt control instruction to the storage control device 3. The interrupt control unit 412 may output the DR request to the storage control device 3 as an interrupt control instruction.

また、判断部４１４は、ＤＲ要請の内容が、蓄電制御装置３での処理が不可であり、かつ要請期間の開始時刻が次回の計画制御指示の作成タイミングよりも遅い場合、計画制御部４１１に計画制御指示の作成を指示する。この場合、計画制御部４１１は、次回の計画制御指示の作成タイミングにおいて、電力の需給状態などの上述した各種情報に加えてＤＲ要請の内容にも基づいて、計画制御指示を作成し、作成した計画制御指示を蓄電制御装置３に出力する。   In addition, when the content of the DR request indicates that the processing by the storage control device 3 is not possible and the start time of the request period is later than the creation timing of the next plan control instruction, the determination unit 414 instructs the plan control unit 411. Instruct to create a plan control instruction. In this case, the plan control unit 411 generates and creates the plan control instruction based on the contents of the DR request in addition to the above-described various information such as the supply and demand state of power at the time of preparation of the next plan control instruction. The plan control instruction is output to the storage control device 3.

次に、指示制御装置４１がＤＲ要請を受け取った際の動作について、図２に示すフローチャートを用いて詳細に説明する。   Next, the operation when the instruction control device 41 receives a DR request will be described in detail using the flowchart shown in FIG.

指示制御装置４１が、電力事業者のサーバ５からＤＲ要請を受け取ると（ステップＳ１）、判断部４１４は、ＤＲ要請の内容を判断する。判断部４１４は、ＤＲ要請の内容が蓄電制御装置３で処理可能な内容であるか否かを判断する（ステップＳ２）。判断部４１４は、ＤＲ要請の内容が蓄電制御装置３で処理可能であると判断した場合（ステップＳ２のＹｅｓ）、ＤＲ要請の要請期間の開始時刻が、次回の計画制御指示の作成タイミングよりも早いか否かを判断する（ステップＳ３）。判断部４１４は、ＤＲ要請の要請期間の開始時刻が、次回の計画制御指示の作成タイミングよりも早い場合（ステップＳ３のＹｅｓ）、割込制御部４１２に割込制御指示の作成を指示する（ステップＳ４）。割込制御指示は、判断部４１４からの指示により、ＤＲ要請の内容に基づいた割込制御指示を作成し、通信部４１３を介して蓄電制御装置３に割込制御指示を出力する（ステップＳ５）。   When the instruction control device 41 receives a DR request from the power provider server 5 (step S1), the determination unit 414 determines the content of the DR request. The determination unit 414 determines whether the content of the DR request is content that can be processed by the storage control device 3 (step S2). When the determination unit 414 determines that the content of the DR request can be processed by the storage control device 3 (Yes in step S2), the start time of the DR request request period is longer than the creation timing of the next plan control instruction. It is determined whether it is early (step S3). If the start time of the DR request request period is earlier than the creation timing of the next plan control instruction (Yes in step S3), the determination unit 414 instructs the interrupt control unit 412 to create an interrupt control instruction ((4) Step S4). The interrupt control instruction creates an interrupt control instruction based on the content of the DR request according to the instruction from the determination unit 414, and outputs the interrupt control instruction to the storage control device 3 via the communication unit 413 (step S5). ).

一方、ステップＳ２において、判断部４１４は、ＤＲ要請の内容が蓄電制御装置３での処理が不可であると判断した場合（ステップＳ２のＮｏ）、計画制御部４１１に計画制御指示の作成を指示する（ステップＳ６）。また、ステップＳ３において、判断部４１４は、ＤＲ要請の要請期間の開始時刻が、次回の計画制御指示の作成タイミングよりも遅い場合（ステップＳ３のＮｏ）、計画制御部４１１に計画制御指示の作成を指示する（ステップＳ６）。計画制御部４１１は、次回の計画制御指示の作成タイミングにおいて、電力の需給状態などの上述した各種情報に加えてＤＲ要請の内容にも基づいて、計画制御指示を作成し、作成した計画制御指示を蓄電制御装置３に出力する（ステップＳ７）。   On the other hand, when the determination unit 414 determines that the content of the DR request can not be processed by the storage control device 3 in step S2 (No in step S2), it instructs the plan control unit 411 to create a plan control instruction. (Step S6). In addition, in step S3, when the start time of the DR request period is later than the creation timing of the next plan control instruction (No in step S3), the determination unit 414 generates the plan control instruction to the plan control unit 411. (Step S6). The plan control unit 411 prepares a plan control instruction based on the contents of the DR request in addition to the above-mentioned various information such as the supply and demand condition of the power at the preparation timing of the next plan control instruction, and prepares the plan control instruction Are output to the storage control device 3 (step S7).

このように、指示制御装置４１は、ＤＲ要請の要請期間の開始時刻までの期間が短く緊急であり、蓄電制御装置３で処理可能である場合、すぐに、このＤＲ要請に基づいた割込制御指示を作成し、作成した割込制御指示を蓄電制御装置３に出力する。一方、指示制御装置４１は、ＤＲ要請の要請期間の開始時刻までの時間が長い場合、あるいはＤＲ要請の内容が複雑な演算処理が必要である場合、計画制御部４１１が演算処理を行って計画制御指示を作成し蓄電制御装置３に出力する。   As described above, when the period up to the start time of the request period of the DR request is short and urgent, and can be processed by the storage control device 3, the instruction control device 41 immediately performs interrupt control based on the DR request. An instruction is generated, and the generated interrupt control instruction is output to the storage control device 3. On the other hand, in the instruction control device 41, when the time until the start time of the DR request period is long, or when the contents of the DR request require complicated operation processing, the plan control unit 411 performs operation processing to perform planning A control instruction is created and output to the storage control device 3.

次に、蓄電制御部３１が蓄電池２１の充放電制御をする際の動作について、図３に示すフローチャートを用いて説明する。   Next, the operation when the storage control unit 31 performs charge / discharge control of the storage battery 21 will be described using the flowchart shown in FIG. 3.

蓄電制御部３１は、記憶部３２に記憶された計画制御指示あるいは割込制御指示に基づいて、蓄電池２１の充放電制御を行う。まず、蓄電制御部３１は、現在の時刻に対応する計画制御指示が記憶部３２に記憶されているか確認する（ステップＳ１１）。蓄電制御部３１は、現在の時刻に対応する計画制御指示が記憶部３２に記憶されている場合（ステップＳ１１のＹｅｓ）、現在の時刻に対応する割込制御指示が記憶部３２に記憶されているか確認する（ステップＳ１２）。蓄電制御部３１は、現在の時刻に対応する割込制御指示が記憶部３２に記憶されている場合（ステップＳ１２のＹｅｓ）、計画制御指示の作成時刻が割込制御指示の作成時刻よりも遅いか否かを確認する（ステップＳ１３）。蓄電制御部３１は、計画制御指示の作成時刻が割込制御指示の作成時刻よりも遅い場合（ステップＳ１３のＹｅｓ）、計画制御指示に基づいて蓄電池２１の充放電を制御する（ステップＳ１４）。   The storage control unit 31 performs charge / discharge control of the storage battery 21 based on a plan control instruction or an interrupt control instruction stored in the storage unit 32. First, the storage control unit 31 confirms whether a plan control instruction corresponding to the current time is stored in the storage unit 32 (step S11). If the storage control unit 31 stores the plan control instruction corresponding to the current time (Yes in step S11), the storage control unit 31 stores the interrupt control instruction corresponding to the current time in the storage unit 32. It is confirmed whether or not there is (step S12). When the storage control unit 32 stores an interrupt control instruction corresponding to the current time (Yes in step S12), the creation time of the plan control instruction is later than the creation time of the interrupt control instruction. Whether or not it is confirmed (step S13). If the creation time of the plan control instruction is later than the creation time of the interrupt control instruction (Yes in step S13), the storage control unit 31 controls charging and discharging of the storage battery 21 based on the plan control instruction (step S14).

一方、ステップＳ１１において、現在の時刻に対応する計画制御指示が記憶部３２に記憶されていない場合（ステップＳ１１のＮｏ）、蓄電制御部３１は、現在の時刻に対応する割込制御指示が記憶部３２に記憶されているか確認する（ステップＳ１５）。蓄電制御部３１は、現在の時刻に対応する割込制御指示が記憶部３２に記憶されている場合（ステップＳ１５のＹｅｓ）、割込制御指示に基づいて蓄電池２１の充放電を制御する（ステップＳ１６）。また、蓄電制御部３１は、現在の時刻に対応する割込制御指示が記憶部３２に記憶されていない場合（ステップＳ１５のＮｏ）、予め設定された指示に基づいて蓄電池２１の充放電を制御する（ステップＳ１７）。「予め設定された指示」の例として、蓄電池２１の充電も放電も行わない“待機”、蓄電制御装置３が蓄電池２１の状態、戸建住宅６の電力需給状態などに基づいて、蓄電池２１の充放電を制御する“自動運転”などが挙げられる。   On the other hand, in step S11, when the plan control instruction corresponding to the current time is not stored in storage unit 32 (No in step S11), storage control unit 31 stores the interrupt control instruction corresponding to the current time. It is checked whether it is stored in the unit 32 (step S15). When the interruption control instruction corresponding to the current time is stored in storage unit 32 (Yes in step S15), storage control unit 31 controls charging / discharging of storage battery 21 based on the interruption control instruction (step S16). In addition, when the interruption control instruction corresponding to the current time is not stored in storage unit 32 (No in step S15), storage control unit 31 controls charging / discharging of storage battery 21 based on a preset instruction. (Step S17). As an example of “preset instruction”, “standby” which neither charges nor discharges the storage battery 21, the state of the storage control device 3 is the storage battery 21, the power supply / demand state of the detached house 6, etc. Examples include "automatic operation" that controls charge and discharge.

また、ステップＳ１２において、現在の時刻に対応する割込制御指示が記憶部３２に記憶されていない場合（ステップＳ１２のＮｏ）、蓄電制御部３１は、計画制御指示に基づいて蓄電池２１の充放電を制御する（ステップＳ１８）。   Further, in step S12, when the interrupt control instruction corresponding to the current time is not stored in storage unit 32 (No in step S12), storage control unit 31 charges / discharges storage battery 21 based on the plan control instruction. Are controlled (step S18).

また、ステップＳ１３において、計画制御指示の作成時刻が割込制御指示の作成時刻よりも早い場合（ステップＳ１３のＮｏ）、蓄電制御部３１は、割込制御指示に基づいて蓄電池２１の充放電を制御する（ステップＳ１９）。   In step S13, when the creation time of the plan control instruction is earlier than the creation time of the interrupt control instruction (No in step S13), the storage control unit 31 charges and discharges the storage battery 21 based on the interrupt control instruction. Control is performed (step S19).

このように、蓄電制御部３１は、現在の時刻に対応する計画制御指示と割込制御指示とが重複して存在する場合、割込制御指示を優先して蓄電池２１の充放電制御を行う。ただし、割込制御指示よりも計画制御指示の方が後に作成されている場合、割込制御指示の内容が計画制御指示に含まれるため、蓄電制御部３１は、計画制御指示に基づいて蓄電池２１の充放電制御を行う。   As described above, when the planned control instruction and the interrupt control instruction corresponding to the current time overlap with each other, the storage control unit 31 performs charge / discharge control of the storage battery 21 with priority given to the interrupt control instruction. However, if the plan control instruction is created later than the interrupt control instruction, the content of the interrupt control instruction is included in the plan control instruction, so the storage control unit 31 determines the storage battery 21 based on the plan control instruction. Perform charge / discharge control of

上述したように、本実施形態の蓄電制御システム１では、指示制御装置４１は、ＤＲ要請の内容が蓄電制御装置３で処理可能な内容で緊急を要する場合、ＤＲ要請を割込制御指示として蓄電制御装置３に出力する。蓄電制御装置３は、割込制御指示を優先して蓄電池２１の充放電制御を行う。すなわち、緊急を要するＤＲ要請は、計画制御指示の作成間隔に関わらず、割込制御指示として蓄電制御装置３として伝達され、この割込制御指示に基づいて蓄電池２１の充放電制御が行われる。したがって、緊急のＤＲ要請の内容を計画制御指示に反映させるために、計画制御指示の作成間隔を短縮する必要がないので、制御サーバ群４の設備を増強する必要がなく、コストの削減を図ることができる。さらに、電力事業者は、緊急のＤＲ要請が制御サーバ群４で遅延することなく蓄電制御装置３に伝達され、蓄電池２１の充放電制御が行われる。すなわち、本実施形態の蓄電制御システム１は、電力調整の要請（ＤＲ要請）から蓄電装置２の動作を制御するまでの応答性を向上させることが可能となる。   As described above, in the storage control system 1 of the present embodiment, the instruction control device 41 stores the DR request as an interrupt control instruction when the content of the DR request requires an emergency with the content that can be processed by the storage control device 3. Output to the control device 3. The storage control device 3 performs charge / discharge control of the storage battery 21 with priority given to the interrupt control instruction. That is, the DR request requiring an emergency is transmitted as the storage control device 3 as an interrupt control instruction regardless of the creation interval of the plan control instruction, and charge and discharge control of the storage battery 21 is performed based on the interrupt control instruction. Therefore, there is no need to shorten the creation interval of the plan control instruction in order to reflect the contents of the urgent DR request in the plan control instruction, so there is no need to increase the facilities of the control server group 4 and the cost is reduced. be able to. Furthermore, in the power company, the urgent DR request is transmitted to the storage control device 3 without delay in the control server group 4, and charge / discharge control of the storage battery 21 is performed. That is, the storage control system 1 of the present embodiment can improve responsiveness from the request for power adjustment (DR request) to the control of the operation of the storage device 2.

また、本実施形態の指示制御装置４１は、蓄電制御システム１に用いられ、計画制御部４１１（第１制御部）を備える。また、本実施形態の指示制御装置４１は、割込制御部４１２（第２制御部）をさらに備える。上記構成の指示制御装置４１によって、電力調整の要請（ＤＲ要請）から蓄電装置２の動作を制御するまでの応答性を向上させることが可能となる。   In addition, the instruction control device 41 of the present embodiment is used for the storage control system 1 and includes a plan control unit 411 (first control unit). The instruction control device 41 of the present embodiment further includes an interrupt control unit 412 (second control unit). By the instruction control device 41 configured as described above, it is possible to improve the responsiveness from the request for power adjustment (DR request) to the control of the operation of the power storage device 2.

また、本実施形態の蓄電制御装置３は、蓄電制御システム１に用いられ、蓄電制御部３１を備える。上記構成の蓄電制御装置３によって、電力調整の要請（ＤＲ要請）から蓄電装置２の動作を制御するまでの応答性を向上させることが可能となる。   Further, the storage control device 3 of the present embodiment is used for the storage control system 1 and includes a storage control unit 31. With the storage control device 3 configured as described above, it is possible to improve the responsiveness from the request for power adjustment (DR request) to the control of the operation of the storage device 2.

また、本実施形態の蓄電制御方法は、蓄電池２１を有し戸建住宅６（需要家施設）に設けられる蓄電装置２、を制御する方法である。蓄電制御方法は、対象期間における蓄電装置２の動作指示内容を示す計画制御指示（第１制御指示）に基づいて蓄電装置２の動作を制御する。また、蓄電制御方法は、対象期間中に蓄電装置２の動作指示内容を示す割込制御指示（第２制御指示）があった場合、割込制御指示に基づいて蓄電装置２の動作を制御する。   Further, the storage control method of the present embodiment is a method of controlling the storage device 2 having the storage battery 21 and provided in the detached house 6 (consumer facility). The storage control method controls the operation of the storage device 2 based on a plan control instruction (first control instruction) indicating the content of the operation instruction of the storage device 2 in the target period. The storage control method also controls the operation of the storage device 2 based on the interrupt control instruction when there is an interrupt control instruction (second control instruction) indicating the content of the operation instruction of the storage device 2 during the target period. .

上記の蓄電制御方法によって、電力調整の要請（ＤＲ要請）から蓄電装置２の動作を制御するまでの応答性を向上させることが可能となる。   With the above storage control method, it is possible to improve responsiveness from the request for power adjustment (DR request) to the control of the operation of the storage device 2.

また、蓄電制御部３１は、コンピュータで構成されており、このコンピュータがプログラムを実行することによって、上述の機能が実現されている。コンピュータは、例えば、メモリと別体に構成されたＣＰＵ（Central Processing Unit）、またはメモリを一体に備えるマイクロコンピュータなどで構成されている。プログラムの提供形態としては、コンピュータに読み取り可能なＲＯＭ（Read Only Memory）、光ディスク等の記録媒体に予め格納されている形態、インターネット等を含む広域通信網を介して記録媒体に供給される形態等がある。   Further, the storage control unit 31 is configured by a computer, and the above-described function is realized by the computer executing a program. The computer is configured of, for example, a CPU (Central Processing Unit) configured separately from a memory, or a microcomputer including a memory integrally. The form of provision of the program may be a ROM (Read Only Memory) readable by a computer, a form stored in advance in a recording medium such as an optical disc, or a form supplied to the recording medium via a wide area communication network including the Internet. There is.

このプログラムは、蓄電池２１を有し戸建住宅６（需要家施設）に設けられる蓄電装置２、を制御するプログラムである。プログラムは、コンピュータを蓄電制御部３１として機能させる。蓄電制御部３１は、対象期間における蓄電装置２の動作指示内容を示す第１制御指示に基づいて蓄電装置２の動作を制御する。また、蓄電制御部３１は、対象期間中に蓄電装置２の動作指示内容を示す第２制御指示があった場合、第２制御指示に基づいて蓄電装置２の動作を制御する。   This program is a program for controlling the power storage device 2 which has the storage battery 21 and is provided in the detached house 6 (consumer facility). The program causes the computer to function as the storage control unit 31. Power storage control unit 31 controls the operation of power storage device 2 based on the first control command indicating the content of the operation command of power storage device 2 in the target period. When the storage control unit 31 receives a second control instruction indicating the content of the operation instruction of the storage device 2 during the target period, the storage control unit 31 controls the operation of the storage device 2 based on the second control instruction.

上記のプログラムによって、電力調整の要請（ＤＲ要請）から蓄電装置２の動作を制御するまでの応答性を向上させることが可能となる。   By the above program, it is possible to improve the responsiveness from the request for power adjustment (DR request) to the control of the operation of the power storage device 2.

また、本実施形態の計画制御部４１１（第１制御部）は、対象期間より短い所定の間隔で計画制御指示（第１制御指示）を蓄電制御部３１に出力する。蓄電制御部３１は、最新の計画制御指示に基づいて蓄電装置２の動作を制御する。   Further, the plan control unit 411 (first control unit) of the present embodiment outputs a plan control instruction (first control instruction) to the storage control unit 31 at a predetermined interval shorter than the target period. The storage control unit 31 controls the operation of the storage device 2 based on the latest plan control instruction.

計画制御部４１１（第１制御部）は、所定の間隔（例えば３０分、１時間）で計画制御指示の更新を行っている。計画制御部４１１は、計画制御指示の更新の都度、対象期間（計画制御指示の作成時から２４時間分）における蓄電池２１の充放電タイミングの計画を作成する。これにより、例えば電力の需給バランスなどに変化が生じた場合、この変化に応じて最適化された蓄電池２１の充放電タイミングの計画である計画制御指示を作成することができる。   The plan control unit 411 (first control unit) updates the plan control instruction at predetermined intervals (for example, 30 minutes, 1 hour). The plan control unit 411 creates a plan of charge / discharge timing of the storage battery 21 in the target period (for 24 hours from the time of creation of the plan control instruction) each time the plan control instruction is updated. Thereby, for example, when a change occurs in the balance of supply and demand of power, etc., it is possible to create a plan control instruction which is a plan of charge / discharge timing of storage battery 21 optimized according to the change.

また、本実施形態の蓄電制御部３１は、計画制御指示（第１制御指示）を受け取れなかった場合、過去に受け取った計画制御指示に基づいて蓄電装置２の動作を制御する。   Further, when the storage control unit 31 of the present embodiment can not receive the plan control instruction (first control instruction), the storage control unit 31 controls the operation of the storage device 2 based on the plan control instruction received in the past.

計画制御指示は、対象期間（例えば２４時間分）より短い所定の間隔（例えば３０分、１時間）で更新されており、更新タイミングが前後する計画制御指示の対象期間が重複する。したがって、指示制御装置４１と蓄電制御装置３との間の通信異常により、蓄電制御装置３が計画制御指示を受信できなかった場合であっても、蓄電制御装置３は、過去に受信した計画制御指示に基づいて蓄電装置２の動作を制御することが可能となる。これにより、蓄電制御システム１の可用性を高く維持することができ、維持コストの削減を図ることが可能となる。   The plan control instruction is updated at a predetermined interval (for example, 30 minutes, 1 hour) shorter than the target period (for example, 24 hours), and the target period of the plan control instruction whose update timings go back and forth overlap. Therefore, even if the storage control device 3 can not receive the plan control instruction due to the communication abnormality between the instruction control device 41 and the storage control device 3, the storage control device 3 receives the plan control received in the past. It is possible to control the operation of power storage device 2 based on the instruction. Thereby, the availability of the storage control system 1 can be maintained high, and the maintenance cost can be reduced.

また、割込制御部４１２（第２制御部）は、買電価格が閾値を超えて変化した場合、割込制御指示（第２制御指示）を蓄電制御部３１に出力するように構成されていてもよい。   Further, the interrupt control unit 412 (second control unit) is configured to output an interrupt control instruction (second control instruction) to the storage control unit 31 when the power purchase price changes beyond the threshold. May be

電力事業者は、市場における電力の買電価格が所定価格（閾値）を上回った場合、蓄電池２１を放電させ、買電価格が所定価格を下回った場合、蓄電池２１を充電させることで、電力の調達コストの削減を図ることができる。市場における電力の買電価格の変動は、例えば５分先などの短時間先を指すことが想定される。本実施形態では、買電価格が所定価格（閾値）を超えて変化した場合に、買電価格に基づいた割込制御指示が蓄電制御部３１に出力される。したがって、蓄電池２１の充放電制御を、買電価格の変動に対してすぐに対応させることができる。   The electric power supplier discharges the storage battery 21 when the purchase price of power in the market exceeds a predetermined price (threshold), and charges the storage battery 21 when the purchase price falls below the predetermined price. Procurement costs can be reduced. The fluctuation of the purchase price of electricity in the market is assumed to indicate a short time ahead, for example, 5 minutes. In the present embodiment, when the purchase price changes to exceed the predetermined price (threshold), an interrupt control instruction based on the purchase price is output to the storage control unit 31. Therefore, charge / discharge control of storage battery 21 can be made to respond promptly to fluctuations in the power purchase price.

なお、本実施形態では、判断部４１４を用いて、ＤＲ要請の内容を、計画制御指示と割込制御指示とのいずれに反映させるか判断しているが、この構成に限定しない。例えば、指示制御装置４１は、ＤＲ要請の内容に関わらず、ＤＲ要請の内容を蓄電制御装置３に伝達し、蓄電制御装置３は、ＤＲ要請の内容に基づいた蓄電装置２の制御が可能であれば、蓄電池２１の充放電制御を行う。また、指示制御装置４１の計画制御部４１１は、次回の計画制御指示の作成タイミングにおいて、ＤＲ要請の内容を反映した計画制御指示を作成し、蓄電制御装置３に出力する。これにより、蓄電制御装置３は、ＤＲ要請の内容が処理可能である場合には、このＤＲ要請の内容に従って蓄電装置２を制御することで、ＤＲ要請から蓄電装置２の動作を制御するまでの応答性を向上させることが可能となる。また、次回の計画制御指示の作成タイミングにおいて、ＤＲ要請の内容を反映した計画制御指示が作成され、蓄電制御装置３は、計画制御指示に従って蓄電池２１を制御することで、より最適化された蓄電池２１の充放電制御を行うことが可能となる。   In the present embodiment, the determination unit 414 is used to determine which of the plan control instruction and the interrupt control instruction the contents of the DR request are to be reflected, but the present invention is not limited to this configuration. For example, the instruction control device 41 transmits the content of the DR request to the storage control device 3 regardless of the content of the DR request, and the storage control device 3 can control the storage device 2 based on the content of the DR request. If it exists, charge and discharge control of the storage battery 21 is performed. Further, the plan control unit 411 of the instruction control device 41 prepares a plan control instruction reflecting the contents of the DR request at the next generation timing of the plan control instruction, and outputs the plan control instruction to the storage control device 3. Thereby, when the content of the DR request can be processed, the storage control device 3 controls the storage device 2 according to the contents of the DR request to control the operation of the storage device 2 from the DR request. It is possible to improve responsiveness. In addition, at the creation timing of the next plan control instruction, a plan control instruction reflecting the contents of the DR request is created, and the storage control device 3 controls the storage battery 21 according to the plan control instruction to further optimize the storage battery. It becomes possible to perform 21 charge / discharge control.

次に、蓄電制御システム１の変形例を図４に示す。本変形例の蓄電制御システム１Ａは、蓄電制御装置３が、割込制御指示を作成する割込制御部３４をさらに備えている。   Next, a modification of the storage control system 1 is shown in FIG. In the storage control system 1A of this modification, the storage control device 3 further includes an interrupt control unit 34 that creates an interrupt control instruction.

本変形例の蓄電制御装置３は、期間監視部３５を備えている。期間監視部３５は、記憶部３２に記憶された計画制御指示の対象期間を監視している。指示制御装置４１と蓄電制御装置３との間の通信に異常などが発生した場合、蓄電制御装置３が指示制御装置４１から計画制御指示を受け取れなくなり、記憶部３２に記憶される計画制御指示の更新がなされず、計画制御指示の対象期間が終了するおそれがある。期間監視部３５は、記憶部３２に記憶された計画制御指示の対象期間を監視し、計画制御指示の対象期間が終了したことを検出し、検出結果を割込制御部３４に通知する。割込制御部３４は、計画制御指示の対象期間が終了した場合、割込制御指示を作成して、蓄電制御部３１に出力する。この場合における割込制御指示の例として、蓄電池２１の充電も放電も行わない“待機”、蓄電制御装置３が蓄電池２１の状態、戸建住宅６の電力需給状態などに基づいて、蓄電池２１の充放電を制御する“自動運転”などが挙げられる。   The storage control device 3 of the present modification includes a period monitoring unit 35. The period monitoring unit 35 monitors the target period of the plan control instruction stored in the storage unit 32. If an abnormality or the like occurs in the communication between the instruction control device 41 and the storage control device 3, the storage control device 3 can not receive the plan control instruction from the instruction control device 41, and the plan control instruction stored in the storage unit 32 The update is not made, and the target period of the plan control instruction may end. The period monitoring unit 35 monitors the target period of the plan control instruction stored in the storage unit 32, detects that the target period of the plan control instruction has ended, and notifies the interruption control unit 34 of the detection result. When the target period of the plan control instruction ends, the interrupt control unit 34 creates an interrupt control instruction and outputs the interrupt control instruction to the storage control unit 31. As an example of the interrupt control instruction in this case, “standby” which neither charges nor discharges the storage battery 21, the state of the storage control device 3 is the storage battery 21, the power demand / supply state of the detached house 6, etc. Examples include "automatic operation" that controls charge and discharge.

このように、割込制御部３４（第２制御部）は、蓄電制御部３１が受け取った計画制御指示（第１制御指示）の対象期間が終了した場合、割込制御指示（第２制御指示）を蓄電制御部３１に出力する。蓄電制御部３１は、割込制御指示に基づいて蓄電装置２の動作を制御する。   Thus, when the target period of the plan control instruction (first control instruction) received by the storage control unit 31 ends, the interruption control unit 34 (second control unit) ) Is output to the storage control unit 31. The storage control unit 31 controls the operation of the storage device 2 based on the interrupt control instruction.

上記構成により、指示制御装置４１と蓄電制御装置３との間における通信異常が一定期間以上継続し、計画制御指示の対象期間が終了した場合であっても、蓄電制御部３１は、蓄電池２１の充放電制御を継続することができる。   According to the above configuration, the storage control unit 31 maintains the communication control unit 31 of the storage battery 21 even if the communication abnormality between the instruction control device 41 and the storage control device 3 continues for a fixed period or more and the target period of the plan control instruction ends. Charge / discharge control can be continued.

ここで、指示制御部によって作成された計画制御指示（蓄電池２１の充放電タイミングの計画）よりも、需要家側の事情の方が優先度が高い場合がある。例えば、需要家であるユーザの操作によって、蓄電池２１の充放電タイミングが指示された場合、割込制御部３４は、ユーザの指示に基づいた割込制御指示を蓄電制御部３１に出力する。この場合、計画制御指示よりも、ユーザの指示（割込制御指示）が優先され、蓄電制御部３１は、ユーザの指示に従って蓄電池２１を充放電制御する。また、発電装置８における太陽電池モジュール８１の発電電力量が急激に低下した場合、割込制御部３４は、戸建住宅６における電力需給のバランスを調整するために、蓄電池２１の放電を指示する割込制御指示を作成する。この場合、計画制御指示が蓄電池２１の充電を指示していたとしても、蓄電制御部３１は、蓄電池２１を放電させる。また、割込制御部３４は、指示制御部からの指示（計画制御指示及び割込制御指示）が蓄電池２１の充放電を頻繁に繰り返す指示であった場合、これらの指示とは異なり蓄電池２１が頻繁に充放電を繰り返さないような指示を作成して蓄電制御部３１に出力する。これにより、蓄電池２１が頻繁に充放電を繰り返すことが抑制され、蓄電池２１の寿命の低下を抑制することが可能となる。   Here, there are cases where the customer's situation has higher priority than the plan control instruction (plan of charge / discharge timing of the storage battery 21) created by the instruction control unit. For example, when the charge / discharge timing of the storage battery 21 is instructed by the operation of the user who is a consumer, the interruption control unit 34 outputs an interruption control instruction based on the instruction of the user to the storage control unit 31. In this case, the user's instruction (interrupt control instruction) is prioritized over the plan control instruction, and the storage control unit 31 performs charge / discharge control of the storage battery 21 according to the user's instruction. In addition, when the amount of power generation of the solar cell module 81 in the power generation device 8 sharply decreases, the interruption control unit 34 instructs discharge of the storage battery 21 in order to adjust the balance of the power supply and demand in the detached house 6. Create an interrupt control instruction. In this case, even if the plan control instruction instructs charging of the storage battery 21, the storage control unit 31 discharges the storage battery 21. Further, when the instruction from the instruction control unit (plan control instruction and interrupt control instruction) is an instruction to repeat charging and discharging of the storage battery 21 frequently, the interrupt control unit 34 differs from these instructions in the storage battery 21. An instruction that does not repeat charging and discharging frequently is created and output to the storage control unit 31. Thereby, it is suppressed that storage battery 21 repeats charge and discharge frequently, and it becomes possible to control a fall of the life of storage battery 21.

このように、割込制御部３４（第２制御部）は、計画制御指示（第１制御指示）が示す蓄電装置２の動作指示内容に修正が必要な事象が発生した場合、この事象に基づいた割込制御指示（第２制御指示）を蓄電制御装置３に出力する。   As described above, when the interruption control unit 34 (second control unit) generates an event that requires correction in the content of the operation instruction of the storage device 2 indicated by the plan control instruction (first control instruction), the interruption control unit 34 (second control unit) The interrupt control instruction (second control instruction) is output to the storage control device 3.

上記構成により、計画制御部４１１が作成した計画制御指示に修正が必要な事象が発生した場合には、この事象に基づいた蓄電池２１の充放電制御が行われ、蓄電池２１の充放電タイミングがより最適化される。また、蓄電制御装置３は、必要に応じて指示制御装置４１からの計画制御指示以外の情報も含めた処理を行うことで、蓄電装置２の設置費用を需要家と電力事業者とで折半し、設置コストの削減、分散を図ることができる。   With the above configuration, when an event requiring correction is generated in the plan control instruction created by the plan control unit 411, charge / discharge control of the storage battery 21 based on this event is performed, and the charge / discharge timing of the storage battery 21 is more Optimized. Further, the storage control device 3 performs processing including information other than the plan control instruction from the instruction control device 41 as needed, so that the installation cost of the storage device 2 is split between the customer and the electric power company. Installation costs can be reduced and distributed.

ここで、蓄電装置２が備える蓄電池２１の劣化などにより、蓄電池２１の交換あるいは蓄電装置２の交換が行われる場合がある。このような場合、交換前と交換後とで、蓄電池２１の充放電制御を見直す必要がある。   Here, the storage battery 21 may be replaced or the storage device 2 may be replaced due to deterioration of the storage battery 21 included in the storage device 2 or the like. In such a case, it is necessary to review charge / discharge control of the storage battery 21 before and after replacement.

そこで、蓄電制御装置３は、蓄電装置２が交換（蓄電池２１のみの交換も含む）されたか否かを判定する交換判定部３６を備えている。交換判定部３６は、蓄電装置２の識別情報を用いて、蓄電装置２の交換有無を判定する。蓄電装置２の識別情報とは、商品コード、製造番号、蓄電池２１の型番、蓄電池２１の接続状態、蓄電池２１の識別番号、蓄電池２１の総セル容量、自立定格出力電力、最大充電電力、最大放電電力などがある。   Therefore, the storage control device 3 includes an exchange determination unit 36 that determines whether the storage device 2 has been replaced (including the replacement of only the storage battery 21). Exchange determination unit 36 uses the identification information of power storage device 2 to determine whether or not power storage device 2 is replaced. The identification information of the storage device 2 includes a product code, a serial number, a model number of the storage battery 21, a connection state of the storage battery 21, an identification number of the storage battery 21, a total cell capacity of the storage battery 21, a free standing rated output power, a maximum charge power, a maximum discharge There is power etc.

蓄電制御装置３に接続され制御対象である蓄電装置２の識別情報は、予め記憶部３２に記憶されている。交換判定部３６は、通信によって蓄電装置２の識別情報を取得し、取得した識別情報（取得識別情報という）と、記憶部３２に記憶されている識別情報（記憶識別情報という）とを比較する。交換判定部３６は、取得識別情報と記憶識別情報とが一致するか否かで、蓄電装置２が交換されたか否かを判定する。交換判定部３６は、取得識別情報と記憶識別情報とが一致する場合、蓄電装置２は交換されていないと判定する。一方、交換判定部３６は、取得識別情報と記憶識別情報とが不一致である場合、蓄電装置２が交換されていると判定する。そして、交換判定部３６は、蓄電装置２の交換有無の判定結果を、割込制御部３４に通知する。   The identification information of the storage device 2 connected to the storage control device 3 and to be controlled is stored in the storage unit 32 in advance. Exchange determining unit 36 acquires identification information of power storage device 2 by communication, and compares the acquired identification information (referred to as acquired identification information) with the identification information stored in storage unit 32 (referred to as storage identification information). . The replacement determination unit 36 determines whether the power storage device 2 has been replaced based on whether the acquired identification information matches the stored identification information. When the acquired identification information and the stored identification information match, the replacement determination unit 36 determines that the power storage device 2 is not replaced. On the other hand, when the acquired identification information and the stored identification information do not match, the replacement determination unit 36 determines that the power storage device 2 is replaced. Then, the replacement determination unit 36 notifies the interrupt control unit 34 of the determination result of the presence or absence of replacement of the power storage device 2.

割込制御部３４は、交換判定部３６が、蓄電装置２が交換されていると判定した場合、割込制御指示を蓄電制御部３１に出力する。この場合における割込制御指示の例として、蓄電池２１の充電も放電も行わない“待機”、蓄電制御装置３が蓄電池２１の状態、戸建住宅６の電力需給状態などに基づいて、蓄電池２１の充放電を制御する“自動運転”などが挙げられる。   The interruption control unit 34 outputs an interruption control instruction to the storage control unit 31 when the replacement determination unit 36 determines that the power storage device 2 is replaced. As an example of the interrupt control instruction in this case, “standby” which neither charges nor discharges the storage battery 21, the state of the storage control device 3 is the storage battery 21, the power demand / supply state of the detached house 6, etc. Examples include "automatic operation" that controls charge and discharge.

なお、本実施形態の蓄電装置２は、電力変換部２２を備える構成であるが、電力変換部２２は、蓄電装置２と別体に設けられた構成であってもよい。また、蓄電制御部３１と蓄電装置２とは、同一の筐体内に設けられ一体に構成されていてもよい。すなわち、蓄電制御装置３、蓄電装置２、及び電力変換部２２は、一体に構成されていてもよいし、それぞれ別体に構成されていてもよい。例えば、電力変換部２２は、蓄電装置２と別体に構成され、蓄電制御装置３と一体に構成されていてもよい。すなわち、蓄電制御装置３は、電力変換部２２をさらに備えた構成であってもよい。これにより、蓄電制御装置３は、蓄電池２１の充電及び放電を行う電力変換装置としても機能することが可能となる。言い換えれば、電力変換装置は、電力変換部２２と蓄電制御部３１とを備えた構成であってもよい。電力変換装置は、蓄電池２１の充電及び放電を行う電力変換部２２と、計画制御指示あるいは割込制御指示に基づいて電力変換部２２を制御することで蓄電池２１の充放電を制御する蓄電制御部３１とを一体に備えている。したがって、電力変換装置は、電力調整の要請（ＤＲ要請）から蓄電装置２が備える蓄電池２１の充放電を制御するまでの応答性をより向上させることが可能となる。   Although the power storage device 2 of the present embodiment includes the power conversion unit 22, the power conversion unit 22 may be provided separately from the power storage device 2. Further, the storage control unit 31 and the storage device 2 may be provided integrally in the same housing. That is, the storage control device 3, the storage device 2, and the power conversion unit 22 may be integrally configured, or may be separately configured. For example, power conversion unit 22 may be configured separately from power storage device 2 and may be configured integrally with power storage control device 3. That is, the storage control device 3 may be configured to further include the power conversion unit 22. Thus, the storage control device 3 can function as a power conversion device that charges and discharges the storage battery 21. In other words, the power conversion device may be configured to include the power conversion unit 22 and the storage control unit 31. The power conversion device controls the charge and discharge of the storage battery 21 by controlling the power conversion unit 22 based on the power conversion unit 22 that charges and discharges the storage battery 21 and the plan control instruction or the interrupt control instruction. It has 31 and one. Therefore, the power conversion device can further improve the responsiveness from the request for power adjustment (DR request) to the control of charging / discharging of storage battery 21 included in power storage device 2.

なお、上述した実施形態は本発明の一例である。このため、本発明は、上述の実施形態に限定されることはなく、この実施形態以外であっても、本発明に係る技術的思想を逸脱しない範囲であれば、設計等に応じて種々の変更が可能であることはもちろんのことである。   The embodiment described above is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and even if it is a range other than this embodiment, various modifications may be made according to design etc. as long as the technical idea of the present invention is not deviated. Of course it is possible to change.
