　連系時間設定部１１０は、蓄電システム１が電力系統２と解列した後、電力系統２における電力供給が可能になった時点から、連系を開始するまでの時間を設定する。本実施の形態における復電とは、蓄電システム１が電力系統２と解列した後、電力系統２からの電力供給が可能になることを示す。また、蓄電システム１が電力系統２と解列した後であって、電力系統２における電力供給が可能になった時点を、以降では復電時刻と呼ぶ。また、復電時刻から、蓄電システム１が、電力系統２と連系を開始するまでの時間（期間）を連系開始時間と呼ぶ。そして、蓄電システム１が復電後に連系することを再連系と呼ぶ。なお、電力系統における電力供給が可能になるとは、復電通知を受領する、系統において電力が供給され所定周波数の範囲内、または所定電圧の範囲内であることを意味する。 The interconnection time setting unit 110 sets the time from when the power storage system 1 is disconnected from the power grid 2 to when the power supply in the power grid 2 is enabled until the start of the grid connection. Power recovery in the present embodiment indicates that power supply from power system 2 becomes possible after power storage system 1 is disconnected from power system 2. In addition, a point in time after the power storage system 1 is disconnected from the power system 2 and power can be supplied to the power system 2 is hereinafter referred to as a power recovery time. In addition, the time (period) from the power recovery time until the power storage system 1 starts connection with the power system 2 is referred to as connection start time. The connection of the power storage system 1 after the power recovery is referred to as reconnection. Note that power supply in the power system is enabled means that a power recovery notification is received and power is supplied in the system and is within a predetermined frequency range or a predetermined voltage range.
　収集部１１１は、蓄電システム１の固有の情報を収集する手段である。蓄電システム１の固有の情報は、例えば、蓄電システム１（または、ＰＣＳ１２、電池システム１３等）の製造番号、蓄電システム１が設置された場所を示す情報、蓄電システム１の利用者を示すユーザ番号等が挙げられるが、これに限定されるものではない。蓄電システム１の固有の情報は、例えば、この蓄電システム１に、以前に、該蓄電システム１によって、または、利用者によって設定された連系開始時間であってもよい。また、蓄電システム１の固有の情報は、例えば、蓄電システム１に含まれる組電池のＳＯＣ（Ｓｔａｔｅ　Ｏｆ　Ｃｈａｒｇｅ）情報であってもよい。また、上記固有の情報には、連系開始時間の優先度を示す情報が含まれていてもよい。この優先度は、例えば、電気料金の高低に応じて設定されるものであってもよい。例えば、電気料金をより多く支払っている需要家に対する優先度をより高く設定してもよい。また、上記固有の情報は、蓄電システム１に含まれる組電池の劣化情報であってもよい。また、上記固有の情報には、現在時刻が含まれてもよい。 The collection unit 111 is a means for collecting information unique to the power storage system 1. Specific information of the power storage system 1 includes, for example, the manufacturing number of the power storage system 1 (or the PCS 12, the battery system 13, etc.), information indicating the location where the power storage system 1 is installed, and the user number indicating the user of the power storage system 1 However, it is not limited to this. The information specific to the power storage system 1 may be, for example, the grid connection start time set in the power storage system 1 by the power storage system 1 or by the user before. Further, the unique information of the power storage system 1 may be, for example, SOC (State Of Charge) information of the assembled battery included in the power storage system 1. Further, the unique information may include information indicating the priority of the interconnection start time. This priority may be set according to, for example, the level of electricity charges. For example, you may set higher the priority with respect to the consumer who has paid more electricity charges. Further, the unique information may be deterioration information of the assembled battery included in the power storage system 1. The unique information may include the current time.
　また、収集部１１１が上記固有の情報を収集する方法は特に限定されない。収集部１１１は、例えば、後述する記憶部１０３に格納された、製造番号等の該蓄電システム１に関する設定情報を、記憶部１０３から取得してもよい。また、収集部１１１は、例えば、蓄電システム１が設置された場所を示す情報をＧＰＳ（Ｇｌｏｂａｌ　Ｐｏｓｉｔｉｏｎｉｎｇ　Ｓｙｓｔｅｍ）を用いて取得してもよい。 Also, the method by which the collection unit 111 collects the unique information is not particularly limited. For example, the collection unit 111 may acquire setting information regarding the power storage system 1 such as a manufacturing number stored in the storage unit 103 described later from the storage unit 103. Moreover, the collection part 111 may acquire the information which shows the place where the electrical storage system 1 was installed, for example using GPS (Global Positioning System).
　また、収集部１１１は、予め電力会社等によって設定された連系開始時間の最小値および最大値を取得する。 In addition, the collection unit 111 acquires the minimum value and the maximum value of the interconnection start time set in advance by an electric power company or the like.
　そして、収集部１１１は、取得した情報を、設定部１１２に出力する。なお、収集部１１１は、連系時間設定部１１０に内蔵されることを例に説明を行ったが、収集部１１１は、連系時間設定部１１０の外部に設けられてもよい。収集部１１１は、蓄電システム１の固有の情報を収集し、収集した情報を設定部１１２に出力できる部位に設けられていればよい。 Then, the collection unit 111 outputs the acquired information to the setting unit 112. Note that the collection unit 111 has been described as being incorporated in the interconnection time setting unit 110, but the collection unit 111 may be provided outside the interconnection time setting unit 110. The collection unit 111 only needs to be provided in a part that collects unique information of the power storage system 1 and can output the collected information to the setting unit 112.
　設定部１１２は、収集部１１１から出力された情報を、該設定部１１２の入力情報として受信する。設定部１１２は、連系開始時間が電力制御システム１０に含まれる複数の蓄電システム１毎に異なるように、該連系開始時間を算出する。例えば、制御装置１００－１の連系時間設定部１１０の設定部１１２は、連系開始時間を、自システム（蓄電システム１－１）が連系する電力系統２に連系可能な他の蓄電システム（蓄電システム１－２～蓄電システム１－Ｎ）の連系開始時間とは異なるように設定する。同様に、制御装置１００－２の連系時間設定部１１０の設定部１１２は、連系開始時間を、自システム（蓄電システム１－２）が連系する電力系統２に連系可能な他の蓄電システム（蓄電システム１－１、蓄電システム１－３～蓄電システム１－Ｎ）の連系開始時間とは異なるように設定する。 The setting unit 112 receives the information output from the collection unit 111 as input information of the setting unit 112. The setting unit 112 calculates the interconnection start time so that the interconnection start time is different for each of the plurality of power storage systems 1 included in the power control system 10. For example, the setting unit 112 of the connection time setting unit 110 of the control device 100-1 sets the connection start time to another power storage system that can be connected to the power system 2 connected to the own system (power storage system 1-1). It is set to be different from the connection start time of the system (power storage system 1-2 to power storage system 1-N). Similarly, the setting unit 112 of the interconnection time setting unit 110 of the control device 100-2 sets the interconnection start time to another power system 2 that can be linked to the power system 2 to which the own system (power storage system 1-2) is linked. It is set to be different from the connection start time of the power storage system (power storage system 1-1, power storage system 1-3 to power storage system 1-N).
　具体的には、設定部１１２は、入力情報に応じて、連系開始時間を算出する。つまり、設定部１１２は、上記入力情報を入力とし、所定の関数を用いて連系開始時間を算出する。このとき、設定部１１２は、連系開始時間が予め電力会社等によって設定された連系開始時間の最小値から最大値の間の値になるように、算出する。設定部１１２が算出に使用する関数は、例えば、乱数関数、ｍｏｄ関数、ハッシュ関数等が挙げられるが、これに限定されるものではない。また、設定部１１２は、上記関数を組み合わせて使用してもよい。そして、設定部１１２は、算出結果を、蓄電システム１の連系開始時間として設定する。 Specifically, the setting unit 112 calculates the interconnection start time according to the input information. That is, the setting unit 112 uses the input information as an input, and calculates the interconnection start time using a predetermined function. At this time, the setting unit 112 calculates the interconnection start time so as to be a value between the minimum value and the maximum value of the interconnection start time set in advance by an electric power company or the like. Examples of functions used by the setting unit 112 for calculation include a random number function, a mod function, and a hash function, but are not limited thereto. The setting unit 112 may use a combination of the above functions. Then, the setting unit 112 sets the calculation result as the connection start time of the power storage system 1.
　なお、設定部１１２は、複数の蓄電システム１における連系開始時間が、予め電力会社等によって設定された連系開始時間の最小値から最大値の間で、一様に分布するように、各蓄電システム１の連系開始時間を設定することが好ましい。また、設定部１１２は、上記固有の情報には、連系開始時間の優先度を示す情報が含まれている場合、この優先度に応じて、連系開始時間の長さを変更してもよい。 The setting unit 112 is configured so that the interconnection start times in the plurality of power storage systems 1 are uniformly distributed between the minimum value and the maximum value of the interconnection start times set in advance by an electric power company or the like. It is preferable to set the connection start time of the power storage system 1. In addition, when the unique information includes information indicating the priority of the interconnection start time, the setting unit 112 may change the length of the interconnection start time according to the priority. Good.
　出力部１１３は、設定部１１２が設定した連系開始時間を連系時間設定部１１０の出力として、出力する。本実施の形態では、出力部１１３は、連系開始時間を制御部１０１に出力する。なお、出力部１１３は、設定部１１２が設定した連系開始時間を、記憶部１０３に格納してもよい。 The output unit 113 outputs the interconnection start time set by the setting unit 112 as an output of the interconnection time setting unit 110. In the present embodiment, output section 113 outputs the interconnection start time to control section 101. Note that the output unit 113 may store the interconnection start time set by the setting unit 112 in the storage unit 103.
　記憶部１０３は、出力部１１３が出力した連系開始時間を格納する。なお、記憶部１０３は、蓄電システム１の設定情報等の固有の情報を格納してもよい。また、記憶部１０３は、制御装置１００の内部に設けられるものであってもよいし、制御装置１００とは別個の記憶装置で実現されるものであってもよい。 The storage unit 103 stores the interconnection start time output by the output unit 113. Note that the storage unit 103 may store unique information such as setting information of the power storage system 1. Further, the storage unit 103 may be provided inside the control device 100 or may be realized by a storage device separate from the control device 100.
　制御部１０１は、スイッチ部１１を制御することにより、自システム（蓄電システム１）の電力系統２への連系を制御する。制御部１０１は、タイマ機能を有している。制御部１０１が有するタイマ機能を、復電タイマとも呼ぶ。制御部１０１は、出力部１１３が出力した連系開始時間を受信し、該連系開始時間を復電タイマの設定時間として使用する。なお、この設定時間は、制御部１０１内の記憶領域に記憶されるものであってもよい。また、制御部１０１は、記憶部１０３に格納された連系開始時間を、復電タイマの設定時間として使用してもよい。 The control unit 101 controls the interconnection of the own system (power storage system 1) to the power system 2 by controlling the switch unit 11. The control unit 101 has a timer function. The timer function that the control unit 101 has is also called a power recovery timer. The control unit 101 receives the interconnection start time output from the output unit 113, and uses the interconnection start time as the set time of the power recovery timer. The set time may be stored in a storage area in the control unit 101. Further, the control unit 101 may use the interconnection start time stored in the storage unit 103 as the set time of the power recovery timer.
　制御部１０１は、スイッチ部１１から送信された信号を受信する。制御部１０１は、受信した信号が解列通知の場合、次に、復電通知を受信するまで、待機する。そして、制御部１０１は、復電通知を受信すると、復電タイマのカウントを開始する。 The control unit 101 receives a signal transmitted from the switch unit 11. When the received signal is a disconnection notification, the control unit 101 waits until receiving a power recovery notification. And the control part 101 will start the count of a power recovery timer, if a power recovery notification is received.
　本実施の形態において、この復電タイマは、カウント開始時からの経過時間（カウント）が設定時間（連系開始時間）となるまで、カウントアップするタイマであるとするが、これに限定されるものではない。復電タイマは、連系開始時間を初期値として設定し、この初期値からカウントダウンするタイマであってもよい。 In this embodiment, the power recovery timer is a timer that counts up until the elapsed time (count) from the count start time reaches a set time (interconnection start time), but is limited to this. It is not a thing. The power recovery timer may be a timer that sets the interconnection start time as an initial value and counts down from this initial value.
　制御部１０１は、復電タイマのカウント中に、停電通知を受信すると、カウントをクリアする。その後、制御部１０１は、復電通知を受信すると再び復電タイマのカウントを開始する。 When the power failure notification is received while the power recovery timer is counting, the control unit 101 clears the count. After that, when receiving the power recovery notification, the control unit 101 starts counting the power recovery timer again.
　制御部１０１は、復電タイマのカウント（経過時間）が連系開始時間になると、スイッチ部１１に対して、スイッチを閉じる指示（連系指示）を制御信号として送信する。この指示に従い、スイッチ部１１がスイッチを閉じることにより、蓄電システム１は、電力系統２に連系することができる。 When the power recovery timer count (elapsed time) reaches the connection start time, the control unit 101 transmits an instruction to close the switch (connection instruction) to the switch unit 11 as a control signal. The power storage system 1 can be linked to the power system 2 by the switch unit 11 closing the switch in accordance with this instruction.
　また、制御部１０１は、カウントを示す情報と、連系開始時間を示す情報とを表示部１０２に出力する。 Also, the control unit 101 outputs information indicating the count and information indicating the interconnection start time to the display unit 102.
　表示部１０２は、復電してから、蓄電システム１が連系を開始するまでの時間を画面に表示する機能を有する。表示部１０２は、カウントを示す情報と、連系開始時間を示す情報とを制御部１０１から受け取り、残りカウントを算出する。そして、表示部１０２は、算出した残りカウントを、蓄電システム１が連系を開始するまでの時間として、画面に表示する。 The display unit 102 has a function of displaying on the screen the time from when the power is restored until the power storage system 1 starts interconnection. The display unit 102 receives information indicating the count and information indicating the interconnection start time from the control unit 101, and calculates the remaining count. Then, the display unit 102 displays the calculated remaining count on the screen as the time until the power storage system 1 starts interconnection.
　なお、表示部１０２は、復電タイマが、設定時間（連系開始時間）からカウントダウンするタイマの場合、カウント自体を画面に表示する構成であってもよい。これにより、蓄電システム１は、利用者に、連系が開始されるまでの時間を提示することができる。 In addition, when the power recovery timer is a timer that counts down from a set time (interconnection start time), the display unit 102 may be configured to display the count itself on the screen. Thereby, the electrical storage system 1 can show a user the time until a grid connection is started.
　なお、表示部１０２に表示される情報は、蓄電システム１が連系を開始するまでの時間に限定されず、例えば、停電を検知したことを示す情報や、復電を検知したことを示す情報であってもよい。 Note that the information displayed on the display unit 102 is not limited to the time until the power storage system 1 starts interconnection, for example, information indicating that a power failure has been detected, or information indicating that a power recovery has been detected. It may be.
　（制御装置１００の処理）
　次に、図３および図４を参照して、制御装置１００の処理の流れについて説明を行う。図３は、本実施の形態に係る制御装置１００の連系時間設定部１１０における、連系時間設定処理の流れの一例を示すフローチャートである。また、図４は、本実施の形態に係る制御装置１００における、再連系制御処理の流れの一例を示すフローチャートである。 (Processing of control device 100)
Next, the processing flow of the control device 100 will be described with reference to FIGS. FIG. 3 is a flowchart showing an example of the flow of the interconnection time setting process in interconnection time setting unit 110 of control device 100 according to the present embodiment. FIG. 4 is a flowchart showing an example of the flow of reconnection control processing in the control device 100 according to the present embodiment.
　図３に示す通り、連系時間設定部１１０の収集部１１１が、連系開始時間の算出に用いる、自システムの固有の情報と、予め電力会社等によって設定された連系開始時間の最小値および最大値を示す情報とを収集する（ステップＳ３１）。 As shown in FIG. 3, the collection unit 111 of the interconnection time setting unit 110 uses information unique to the system used for calculating the interconnection start time, and the minimum value of the interconnection start time set in advance by an electric power company or the like. And information indicating the maximum value are collected (step S31).
　次に、設定部１１２が、ステップＳ３１で収集された情報を入力情報として用いて、該入力情報に応じて、連系開始時間を算出する（ステップＳ３２）。そして、設定部１１２が算出結果を自システムの連系開始時間として設定し（ステップＳ３３）、連系時間設定処理を終了する。 Next, the setting unit 112 uses the information collected in step S31 as input information, and calculates the interconnection start time according to the input information (step S32). Then, the setting unit 112 sets the calculation result as the connection start time of the own system (step S33), and ends the connection time setting process.
　このように、設定部１１２が連系開始時間の算出に使用する入力情報は、蓄電システム１に固有の情報である。そのため、電力制御システム１０に含まれる複数の蓄電システム１の制御装置１００の夫々に備えられた設定部１１２は、電力制御システム１０に含まれる複数の蓄電システム１毎に異なる連系開始時間を、自システム（蓄電システム１）に設定することができる。 Thus, the input information used by the setting unit 112 for calculating the interconnection start time is information unique to the power storage system 1. Therefore, the setting unit 112 provided in each of the control devices 100 of the plurality of power storage systems 1 included in the power control system 10 has different interconnection start times for the plurality of power storage systems 1 included in the power control system 10. It can be set to its own system (power storage system 1).
　次に、本実施の形態に係る制御装置１００における、再連系制御処理について説明する。なお、図４では、蓄電システム１が電力系統２と連系していない状態（解列通知を受信した後の状態）であることを前提に説明を行う。 Next, reconnection control processing in the control device 100 according to the present embodiment will be described. In FIG. 4, the description will be made on the assumption that the power storage system 1 is not connected to the power system 2 (the state after receiving the disconnection notification).
　図４に示す通り、制御装置１００の制御部１０１は、復電を検知したスイッチ部１１から復電通知を受信する（ステップＳ４１）と、復電タイマのカウントを開始する（ステップＳ４２）。そして、制御部１０１は、カウントが設定時間（連系開始時間）になったか否かを確認する（ステップＳ４３）。 As shown in FIG. 4, when the control unit 101 of the control device 100 receives a power recovery notification from the switch unit 11 that has detected power recovery (step S41), the control unit 101 starts counting a power recovery timer (step S42). Then, the control unit 101 confirms whether or not the count has reached a set time (interconnection start time) (step S43).
　そして、制御部１０１は、カウントが設定時間でないとき（ステップＳ４３にてＮＯ）に、停電通知を受信したか否かを確認する（ステップＳ４４）。停電通知を受信していない場合（ステップＳ４４にてＮＯ）、制御部１０１は、処理をステップＳ４３に戻す。 And the control part 101 confirms whether the power failure notification was received when a count is not set time (it is NO at step S43) (step S44). If a power failure notification has not been received (NO in step S44), control unit 101 returns the process to step S43.
　停電通知を受信した場合（ステップＳ４４にてＹＥＳ）、制御部１０１は、カウントをクリアし（ステップＳ４５）、処理をステップＳ４１に戻し、次の復電通知を受信するまで待機する。 If a power failure notification is received (YES in step S44), control unit 101 clears the count (step S45), returns the process to step S41, and waits until the next power recovery notification is received.
　カウントが設定時間となったとき（ステップＳ４３にてＹＥＳ）、制御部１０１は、スイッチ部１１に連系指示を送信する（ステップＳ４６）。 When the count reaches the set time (YES in step S43), the control unit 101 transmits an interconnection instruction to the switch unit 11 (step S46).
　連系指示を受け取ったスイッチ部１１は、スイッチを閉じて、蓄電システム１を電力系統２に連系させる。これにより、蓄電システム１は、電力系統２に連系することができる。 The switch unit 11 that has received the interconnection instruction closes the switch to link the power storage system 1 to the power system 2. Thereby, the power storage system 1 can be linked to the power system 2.
　（効果）
　本実施の形態に係る制御装置１００によれば、蓄電システム１の再連系時であっても、電力系統２の安定性を向上させることができる。なぜならば、電力系統２に連系可能な複数の蓄電システム１の制御装置１００の夫々に備えられた連系時間設定部１１０が、蓄電システム１が電力系統２と解列後に電力系統２における電力供給が可能になった時点から、連系を開始するまでの時間を示す連系開始時間を設定するからである。このとき、連系時間設定部１１０は、連系開始時間を蓄電システム１毎に異なるように設定する。 (effect)
According to control device 100 according to the present embodiment, it is possible to improve the stability of power system 2 even when power storage system 1 is reconnected. This is because the connection time setting unit 110 provided in each of the control devices 100 of the plurality of power storage systems 1 that can be connected to the power system 2 has the power in the power system 2 after the power storage system 1 is disconnected from the power system 2. This is because the connection start time indicating the time from when supply becomes possible until the start of connection is set. At this time, interconnection time setting unit 110 sets the interconnection start time to be different for each power storage system 1.
　これにより、蓄電システム１は、電力系統２との解列後に該電力系統２における電力供給が可能になった時点から、設定された連系開始時間経過後に、電力系統２に連系することができる。この連系開始時間は、蓄電システム１毎に異なるように設定されているため、連系開始時間が固定的に設定されていた場合と比べ、一度に多数の蓄電システム１が電力系統２に連系することを防ぐことができる。 As a result, the power storage system 1 can be connected to the power system 2 after the set connection start time has elapsed from the time when power supply in the power system 2 becomes possible after disconnecting from the power system 2. it can. Since this grid connection start time is set to be different for each power storage system 1, a larger number of power storage systems 1 are connected to the power system 2 at a time than when the grid connection start time is fixedly set. It is possible to prevent the system.
　また、本実施の形態に係る制御装置１００によれば、電力会社の作業者等が、例えば、蓄電システム１を設置するときに、どの蓄電システム１にどれくらいの長さの連系開始時間を設定すれば電力系統２が安定するのかを考えて設定する場合に比べ、該作業者の手間を省くことができる。 Further, according to the control device 100 according to the present embodiment, when a power company worker or the like installs the power storage system 1, for example, how long the grid connection start time is set in which power storage system 1 Then, compared with the case where it sets in consideration of whether the electric power grid | system 2 is stabilized, the said operator's effort can be saved.
　＜第２の実施の形態＞
　次に、本発明の第２の実施の形態について、図面を参照して説明する。なお、説明の便宜上、前述した第１の実施の形態で説明した図面に含まれる部材と同じ機能を有する部材については、同じ符号を付し、その説明を省略する。 <Second Embodiment>
Next, a second embodiment of the present invention will be described with reference to the drawings. For convenience of explanation, members having the same functions as those included in the drawings described in the first embodiment described above are given the same reference numerals, and descriptions thereof are omitted.
　第１の実施の形態では、設定部１１２が、自システムが連系可能な電力系統２に連系可能な他の蓄電システム、とは異なるように、連系開始時間を設定することについて説明したが、これに限定されるものではない。設定部１１２は、蓄電システム１の連系開始時間を、同じ電力系統に連系された、１以上の蓄電システム１を含む蓄電システム群毎に異なるように、且つ、１つの蓄電システム群に含まれる１以上の蓄電システム１は同じになるように、設定してもよい。 In 1st Embodiment, the setting part 112 demonstrated setting the connection start time so that it might differ from the other electrical storage system which can be connected with the electric power grid | system 2 which can connect with a self-system. However, the present invention is not limited to this. The setting unit 112 includes the connection start time of the power storage system 1 so as to be different for each power storage system group including one or more power storage systems 1 connected to the same power system and included in one power storage system group. One or more power storage systems 1 may be set to be the same.
　図５は、本実施の形態に係る蓄電システム１を含む電力制御システム２０の全体構成の概略の一例を示す図である。電力制御システム２０は、第１の実施の形態に係る電力制御システム１０と同様に、電力系統２と、電力系統２に連系可能な複数の蓄電システムを含んでいる。 FIG. 5 is a diagram illustrating an example of an outline of the overall configuration of the power control system 20 including the power storage system 1 according to the present embodiment. Similar to the power control system 10 according to the first embodiment, the power control system 20 includes a power system 2 and a plurality of power storage systems that can be linked to the power system 2.
　複数の蓄電システム１の夫々は、１以上の蓄電システム１を含む蓄電システム群の何れかに属している。図５において、破線で示した矩形は、蓄電システム群の一例を示している。 Each of the plurality of power storage systems 1 belongs to one of the power storage system groups including one or more power storage systems 1. In FIG. 5, the rectangle shown with the broken line has shown an example of the electrical storage system group.
　複数の蓄電システム１の夫々は、所定のルールに基づいて各蓄電システム群にグループ分けされる。例えば、あるビルの各階に、蓄電システム１が設置されている場合、蓄電システム１は、設置された階に応じたグループに分けられるものであってもよい。例えば、奇数階に設置された蓄電システム１を１つのグループにし、偶数階に設置された蓄電システム１を１つのグループにしてもよい。また、蓄電システム１が設置された場所（住所）を示す情報を用いて、所定範囲内に含まれる蓄電システム１を同じグループにしてもよい。また、上記住所を示す情報を用いて、所定範囲内に含まれる蓄電システム１は、夫々異なるグループに属するようにしてもよい。このように、蓄電システム群にどの蓄電システム１を含めるかについては、特に限定されるものではない。 Each of the plurality of power storage systems 1 is grouped into each power storage system group based on a predetermined rule. For example, when the power storage system 1 is installed on each floor of a building, the power storage system 1 may be divided into groups according to the installed floor. For example, the power storage systems 1 installed on the odd floors may be combined into one group, and the power storage systems 1 installed on the even floors may be combined into one group. Moreover, you may make the electrical storage system 1 contained in the predetermined range into the same group using the information which shows the place (address) where the electrical storage system 1 was installed. Moreover, you may make it the electrical storage system 1 contained in a predetermined range belong to a respectively different group using the information which shows the said address. As described above, which power storage system 1 is included in the power storage system group is not particularly limited.
　この蓄電システム群に含まれる蓄電システム１の夫々に含まれる制御装置１００の機能構成は、図２に示す制御装置１００と同様であるため、図２を参照して説明する。 The functional configuration of the control device 100 included in each of the power storage systems 1 included in this power storage system group is the same as that of the control device 100 shown in FIG. 2, and will be described with reference to FIG.
　収集部１１１は、自システム（蓄電システム１）が属する（含まれる）蓄電システム群の固有の情報を収集する。この固有の情報は、第１の実施の形態に係る収集部１１１が収集する情報と同様であるため、説明を省略する。収集部１１１は、収集した情報を設定部１１２に出力する。 The collection unit 111 collects unique information of the power storage system group to which the own system (power storage system 1) belongs (included). Since this unique information is the same as the information collected by the collection unit 111 according to the first embodiment, a description thereof will be omitted. The collection unit 111 outputs the collected information to the setting unit 112.
　設定部１１２は、収集部１１１から出力された情報を、該設定部１１２の入力情報として受信する。そして、設定部１１２は、連系開始時間が、電力制御システム２０に含まれる複数の蓄電システム群毎に異なるように、該連系開始時間を算出する。つまり、設定部１１２は、自システムの連系開始時間を、自システムが属する蓄電システム群とは異なる蓄電システム群に含まれる蓄電システム１であって、同じ電力系統２に連系可能な蓄電システム１の連系開始時間とは異なるように、算出する。そして、算出した連系開始時間を自システムに設定する。このとき、設定部１１２は、自システムが属する蓄電システム群に属する他の蓄電システム１と同じ連系開始時間になるように、自システムの連系開始時間を設定する。 The setting unit 112 receives the information output from the collection unit 111 as input information of the setting unit 112. Then, setting unit 112 calculates the interconnection start time so that the interconnection start time is different for each of the plurality of power storage system groups included in power control system 20. That is, the setting unit 112 is a power storage system 1 included in a power storage system group different from the power storage system group to which the self system belongs, and the power storage system that can be connected to the same power system 2 It is calculated so as to be different from the connection start time of 1. Then, the calculated interconnection start time is set in the own system. At this time, the setting unit 112 sets the interconnection start time of the own system so as to be the same interconnection start time as other power storage systems 1 belonging to the power storage system group to which the own system belongs.
　このように、本実施の形態に係る制御装置１００は、１以上の蓄電システム１が属する蓄電システム群毎に異なるように、且つ、同じ蓄電システム群に含まれる１以上の蓄電システム１は同じになるように、連系開始時間を設定する。これにより、同じグループ（蓄電システム群）に含まれる蓄電システム１は、同じタイミングで電力系統２に連系することができる。また、異なるグループに属する蓄電システム１は、異なるタイミングで電力系統２に連系するため、第１の実施の形態と同様に、再連系時であっても、電力系統２の安定性を向上させることができる。 Thus, control device 100 according to the present embodiment is different for each power storage system group to which one or more power storage systems 1 belong, and one or more power storage systems 1 included in the same power storage system group are the same. Set the interconnection start time so that Thereby, the power storage systems 1 included in the same group (power storage system group) can be connected to the power system 2 at the same timing. In addition, since the power storage systems 1 belonging to different groups are connected to the power system 2 at different timings, the stability of the power system 2 is improved even during re-connection, as in the first embodiment. Can be made.
　＜第３の実施の形態＞
　次に、本発明の第３の実施の形態について、図６および図７を参照して説明する。なお、説明の便宜上、前述した第１の実施の形態で説明した図面に含まれる部材と同じ機能を有する部材については、同じ符号を付し、その説明を省略する。 <Third Embodiment>
Next, a third embodiment of the present invention will be described with reference to FIGS. For convenience of explanation, members having the same functions as those included in the drawings described in the first embodiment described above are given the same reference numerals, and descriptions thereof are omitted.
　上述した第１および第２の実施の形態では、連系開始時間は、設定部１１２によって固定的に設定されることについて説明したが、これに限定されるものではない。設定部１１２は、連系開始時間を都度変更するものであってもよい。 In the first and second embodiments described above, it has been described that the interconnection start time is fixedly set by the setting unit 112, but the present invention is not limited to this. The setting unit 112 may change the connection start time each time.
　本実施の形態では、連系開始時間を、前記電力系統との解列後に前記電力系統からの電力供給が可能になる度に設定することについて説明する。 In the present embodiment, a description will be given of setting the interconnection start time every time power can be supplied from the power system after disconnecting from the power system.
　図６は、本実施の形態に係る制御装置１００の機能構成の一例を示す機能ブロック図である。また、図７は、本実施の形態に係る制御装置１００の再連系制御処理の流れの一例を示すフローチャートである。 FIG. 6 is a functional block diagram illustrating an example of a functional configuration of the control device 100 according to the present embodiment. FIG. 7 is a flowchart showing an example of the flow of reconnection control processing of the control device 100 according to the present embodiment.
　なお、本実施の形態に係る制御装置１００の連系時間設定部１１０は、第１の実施の形態に係る連系時間設定部１１０と同様に、蓄電システム１毎に異なるように、連系開始時間を設定するとして説明を行うが、これに限定されるものではない。本実施の形態に係る制御装置１００の連系時間設定部１１０は、第２の実施の形態に係る連系時間設定部１１０と同様に、１以上の蓄電システム１を含む蓄電システム群毎に異なるように、連系開始時間を設定してもよい。 It should be noted that the interconnection time setting unit 110 of the control device 100 according to the present embodiment starts the interconnection start so as to be different for each power storage system 1, similarly to the interconnection time setting unit 110 according to the first embodiment. Although the description will be made assuming that the time is set, the present invention is not limited to this. Similarly to interconnection time setting unit 110 according to the second embodiment, interconnection time setting unit 110 of control device 100 according to the present embodiment differs for each power storage system group including one or more power storage systems 1. In this way, the interconnection start time may be set.
　図６に示す通り、本実施の形態に係る制御装置１００は、制御部１０１、表示部１０２および連系時間設定部（連系時間設定装置）１１０を備えている。また、連系時間設定部１１０は、収集部１１１、設定部１１２および出力部１１３を備えている。また、制御装置１００は、記憶部１０３を更に備える構成であってもよい。 As shown in FIG. 6, the control device 100 according to the present embodiment includes a control unit 101, a display unit 102, and an interconnection time setting unit (interconnection time setting device) 110. The interconnection time setting unit 110 includes a collection unit 111, a setting unit 112, and an output unit 113. The control device 100 may further include a storage unit 103.
　本実施の形態に係る制御装置１００と、第１の実施の形態に係る制御装置１００との異なる点は、制御部１０１から収集部１１１に対して、信号を送信する点である。以下では、図６の各部の処理を、図７のフローチャートを参照しながら説明する。なお、図７では、蓄電システム１が電力系統２と連系していない状態（解列通知を受信した後の状態）であることを前提に説明を行う。 The difference between the control device 100 according to the present embodiment and the control device 100 according to the first embodiment is that a signal is transmitted from the control unit 101 to the collection unit 111. Hereinafter, the processing of each unit in FIG. 6 will be described with reference to the flowchart in FIG. In FIG. 7, the description will be made on the assumption that the power storage system 1 is not connected to the power system 2 (the state after receiving the disconnection notification).
　図７に示す通り、まず、制御部１０１は、復電を検知したスイッチ部１１から復電通知を受信する（ステップＳ７１）と、復電タイマのカウントを開始する（ステップＳ７２）。また、制御部１０１は、連系時間設定部１１０の収集部１１１に対し、復電通知を受信したことを示す信号を送信する。制御部１０１は、この信号の送信をステップＳ７２と同時に行ってもよい。 As shown in FIG. 7, first, when the control unit 101 receives a power recovery notification from the switch unit 11 that has detected power recovery (step S71), the control unit 101 starts counting a power recovery timer (step S72). In addition, the control unit 101 transmits a signal indicating that the power recovery notification has been received to the collection unit 111 of the interconnection time setting unit 110. The control unit 101 may transmit this signal simultaneously with step S72.
　収集部１１１は、制御部１０１から、復電通知を受信したことを示す信号を受信すると、連系開始時間の算出に用いる、自システムの固有の情報と、予め電力会社等によって設定された連系開始時間の最小値および最大値を示す情報とを収集する（ステップＳ７３）。 When the collection unit 111 receives a signal indicating that the power recovery notification has been received from the control unit 101, the collection unit 111 uses information unique to the system used for calculating the interconnection start time, and a link set in advance by a power company or the like. Information indicating the minimum value and the maximum value of the system start time is collected (step S73).
　また、設定部１１２は、入力情報に応じて、連系開始時間を算出し（ステップＳ７４）、算出結果を自システムの連系開始時間として設定する（ステップＳ７５）。このステップＳ７３～ステップＳ７５は、第１の実施の形態において説明した連系時間設定処理（ステップＳ３１～ステップＳ３３）と同様の処理である。そして、出力部１１３は、設定部１１２が設定した連系開始時間を連系時間設定部１１０の出力として、制御部１０１に出力する。なお、出力部１１３は、設定部１１２が設定した連系開始時間を、記憶部１０３に格納してもよい。 Also, the setting unit 112 calculates the interconnection start time according to the input information (step S74), and sets the calculation result as the interconnection start time of the own system (step S75). Steps S73 to S75 are the same as the interconnection time setting process (steps S31 to S33) described in the first embodiment. Then, the output unit 113 outputs the interconnection start time set by the setting unit 112 to the control unit 101 as an output of the interconnection time setting unit 110. Note that the output unit 113 may store the interconnection start time set by the setting unit 112 in the storage unit 103.
　次に、制御部１０１は、ステップＳ４３と同様に、カウントが設定時間（連系開始時間）になったか否かを確認する（ステップＳ７６）。そして、制御部１０１は、カウントが設定時間でないとき（ステップＳ７６にてＮＯ）に、停電通知を受信したか否かを確認する（ステップＳ７７）。停電通知を受信していない場合（ステップＳ７７にてＮＯ）、制御部１０１は、処理をステップＳ７６に戻す。 Next, similarly to step S43, the control unit 101 confirms whether or not the count has reached the set time (interconnection start time) (step S76). Then, control unit 101 confirms whether or not a power failure notification has been received when the count is not the set time (NO in step S76) (step S77). If a power failure notification has not been received (NO in step S77), control unit 101 returns the process to step S76.
　停電通知を受信した場合（ステップＳ７７にてＹＥＳ）、制御部１０１は、カウントをクリアする（ステップＳ７８）。そして、制御部１０１は、復電を検知したスイッチ部１１から復電通知を受信する（ステップＳ７９）と、再度、復電タイマのカウントを開始する（ステップＳ８０）。そして、制御部１０１は、処理をステップＳ７６に戻す。 When a power failure notification is received (YES in step S77), control unit 101 clears the count (step S78). Then, when the control unit 101 receives a power recovery notification from the switch unit 11 that has detected power recovery (step S79), the control unit 101 starts counting the power recovery timer again (step S80). Then, the control unit 101 returns the process to step S76.
　カウントが設定時間となったとき（ステップＳ７６にてＹＥＳ）、制御部１０１は、スイッチ部１１に連系指示を送信する（ステップＳ８１）。 When the count reaches the set time (YES in step S76), the control unit 101 transmits an interconnection instruction to the switch unit 11 (step S81).
　連系指示を受け取ったスイッチ部１１は、スイッチを閉じて、蓄電システム１を電力系統２に連系させる。これにより、蓄電システム１は、電力系統２に連系することができる。 The switch unit 11 that has received the interconnection instruction closes the switch to link the power storage system 1 to the power system 2. Thereby, the power storage system 1 can be linked to the power system 2.
　本実施の形態では、スイッチが開放された状態において、停電通知を受信した（ステップＳ７７）後に、復電通知を受信した（ステップＳ７９）場合、制御部１０１は、ステップＳ７３～Ｓ７５の連系時間設定処理で設定された連系開始時間を復電タイマの設定時間として用いた。しかし、制御装置１００は、ステップＳ７８の後に、ステップＳ７１に処理を戻し、再度連系開始時間を設定する処理を行ってもよい。つまり、本実施の形態に係る制御装置１００は、蓄電システム１が電力系統２に連系後、解列した後毎に連系開始時間を設定してもよいし、スイッチ部１１のセンサが所定の値を超えた電圧を検知したとき毎に、連系開始時間を設定してもよい。 In this embodiment, when the power recovery notification is received (step S79) after the power failure notification is received (step S77) in a state where the switch is opened, the control unit 101 performs the interconnection time of steps S73 to S75. The grid connection start time set in the setting process was used as the power recovery timer setting time. However, the control device 100 may return the process to step S71 after step S78 and perform the process of setting the interconnection start time again. That is, the control device 100 according to the present embodiment may set the connection start time every time the power storage system 1 is connected to the power system 2 and then disconnected, or the sensor of the switch unit 11 is predetermined. The interconnection start time may be set every time a voltage exceeding the value of is detected.
　このとき、設定部１１２は、連系開始時間が電力制御システム１０に含まれる複数の蓄電システム１毎に異なるように、且つ、前回に算出した値と異なるように、連系開始時間を算出する。このとき、所定の関数に入力する情報として、蓄電システム１の設定情報のように固定の情報だけでなく、該制御装置１００が前回算出した連系開始時間を用いることが好ましい。また、所定の関数に入力する情報として、現在時刻であってもよい。これにより、例えば、所定の関数が、入力が同じものは同じ結果を出力するような関数であっても、所定の関数に入力する情報が算出する度に変更されるため、設定部１１２は、異なる結果を出力することができる。 At this time, the setting unit 112 calculates the interconnection start time so that the interconnection start time is different for each of the plurality of power storage systems 1 included in the power control system 10 and is different from the previously calculated value. . At this time, it is preferable to use not only fixed information like the setting information of the power storage system 1 but also the interconnection start time calculated by the control device 100 last time as information to be input to the predetermined function. Moreover, the current time may be used as information input to a predetermined function. Thus, for example, even if the predetermined function is a function that outputs the same result if the input is the same, the setting unit 112 is changed every time information input to the predetermined function is calculated. Different results can be output.
　（効果）
　本実施の形態に係る制御装置１００によれば、第１の実施の形態に係る制御装置１００と同様に、蓄電システム１の再連系時であっても、電力系統２の安定性を向上させることができる。 (effect)
According to the control device 100 according to the present embodiment, the stability of the electric power system 2 is improved even when the power storage system 1 is reconnected, similarly to the control device 100 according to the first embodiment. be able to.
　また、固定的に連系開始時間が設定されている場合、複数の蓄電システム１の夫々における時間であって、復電から再連系までの時間に差が出てしまう可能性がある。したがって、このような場合、蓄電システム１間の公平性が低くなる可能性がある。 In addition, when the connection start time is fixedly set, there is a possibility that the time from the power recovery to the reconnection will be different in each of the plurality of power storage systems 1. Therefore, in such a case, the fairness between the power storage systems 1 may be lowered.
　しかしながら、本実施の形態に係る制御装置１００は、設定部１１２が、連系開始時間を復電通知を受信する度に変更するため、各蓄電システム１に対する公平性をより高めることができる。 However, in the control device 100 according to the present embodiment, the setting unit 112 changes the connection start time each time a power recovery notification is received, and therefore, the fairness for each power storage system 1 can be further improved.
　＜第４の実施の形態＞

　次に、図９を参照して、電力制御システム３０に含まれる制御装置２００および連系時間設定装置３００の機能構成について説明する。図９は、本実施の形態に係る電力制御システム３０における蓄電システム１の制御装置２００、および、連系時間設定装置３００の機能構成の一例を示す機能ブロック図である。 Next, with reference to FIG. 9, functional configurations of the control device 200 and the interconnection time setting device 300 included in the power control system 30 will be described. FIG. 9 is a functional block diagram illustrating an example of functional configurations of the control device 200 of the power storage system 1 and the interconnection time setting device 300 in the power control system 30 according to the present embodiment.
　（連系時間設定装置３００）
　図９に示す通り、連系時間設定装置３００は、収集部１１１、設定部１１２および出力部１１３を備えた連系時間設定部１１０を備えている。なお、図９に示す連系時間設定装置３００は、本発明の実施の形態に特有な構成について示したものであり、図９に示す連系時間設定装置３００が図９に示されていない部材（例えば、蓄電システム１の充放電を制御する部材等）を有していてもよいことは言うまでもない。 (Linkage time setting device 300)
As shown in FIG. 9, the interconnection time setting device 300 includes an interconnection time setting unit 110 including a collection unit 111, a setting unit 112, and an output unit 113.

Needless to say, a member (for example, a member for controlling charge / discharge of the power storage system 1) may be included.
　収集部１１１は、蓄電システム１の固有の情報を収集する際、収集対象の蓄電システム１の制御装置２００に対して、情報を要求する通知（情報要求）を送信する。そして、収集部１１１は、制御装置２００から情報要求に対する回答として、該蓄電システム１の固有の情報を受信することにより、蓄電システム１の固有の情報を収集する。 The collecting unit 111 transmits a notification (information request) for requesting information to the control device 200 of the power storage system 1 to be collected when collecting the specific information of the power storage system 1. Then, the collection unit 111 collects the unique information of the power storage system 1 by receiving the unique information of the power storage system 1 as an answer to the information request from the control device 200.
　そして、設定部１１２は、収集部１１１が収集した情報を用いて、連系開始時間が電力制御システム３０に含まれる複数の蓄電システム１毎に異なるように、情報を送信した蓄電システム１の連系開始時間を設定する。 Then, the setting unit 112 uses the information collected by the collecting unit 111 so that the connection start time of the plurality of power storage systems 1 included in the power control system 30 is different for each of the power storage systems 1 that transmitted the information.

　なお、設定部１１２は、固有の情報に、蓄電システム１が設置された場所を示す情報が含まれる場合、この場所に応じて連系開始時間を算出してもよい。例えば、蓄電システム１が設置された位置が近いもの同士の連系開始時間が大きく異なるように、設定部１１２は、各蓄電システム１の連系開始時間を算出してもよい。 In addition, when the information indicating the location where the power storage system 1 is installed is included in the unique information, the setting unit 112 may calculate the interconnection start time according to this location. For example, the setting unit 112 may calculate the connection start time of each power storage system 1 so that the connection start times of those close to the positions where the power storage systems 1 are installed are greatly different.
　そして、出力部１１３は、設定部１１２が設定した連系開始時間を、該連系開始時間が設定された蓄電システム１の制御装置２００に対して送信（出力）する。 Then, the output unit 113 transmits (outputs) the interconnection start time set by the setting unit 112 to the control device 200 of the power storage system 1 in which the interconnection start time is set.
　（制御装置２００）
　図９に示す通り、制御装置２００は、制御部１０１、表示部１０２、送信部２０４および受信部２０５を備えている。また、制御装置２００は、記憶部１０３を更に備える構成であってもよい。 (Control device 200)
As illustrated in FIG. 9, the control device 200 includes a control unit 101, a display unit 102, a transmission unit 204, and a reception unit 205. The control device 200 may further include a storage unit 103.
　受信部２０５は連系時間設定装置３００から送信された情報要求を受信すると、その旨を示す信号を送信部２０４に送信する。また、受信部２０５は、連系時間設定装置３００から送信された連系開始時間を、制御部１０１に出力する。なお、受信部２０５は、受信した連系開始時間を、記憶部１０３に格納してもよい。 When receiving the information request transmitted from the interconnection time setting device 300, the receiving unit 205 transmits a signal indicating that to the transmitting unit 204. In addition, the reception unit 205 outputs the connection start time transmitted from the connection time setting device 300 to the control unit 101. Note that the receiving unit 205 may store the received interconnection start time in the storage unit 103.
　送信部２０４は、受信部２０５から情報要求を受信したことを示す信号を受信すると、連系時間設定装置３００に対して、自制御装置２００を含む蓄電システム１（自システム）の固有の情報を送信する。送信部２０４は、例えば、記憶部１０３に格納された、製造番号等の該蓄電システム１に関する設定情報を、記憶部１０３から取得して、連系時間設定装置３００に送信してもよい。送信部２０４が、自システムの固有の情報を取得する方法は、特に限定されない。 When the transmission unit 204 receives a signal indicating that the information request has been received from the reception unit 205, the transmission unit 204 sends to the interconnection time setting device 300 unique information of the power storage system 1 (own system) including the own control device 200.

Note that the storage unit 103 may store unique information such as setting information of the power storage system 1. The storage unit 103 may be provided inside the control device 200 or may be realized by a storage device that is separate from the control device 200.
　制御部１０１および表示部１０２の夫々の動作は、第１の実施の形態における制御部１０１および表示部１０２と同様であるため、本実施の形態では、その説明を省略する。 Since the operations of the control unit 101 and the display unit 102 are the same as those of the control unit 101 and the display unit 102 in the first embodiment, description thereof is omitted in this embodiment.
　なお、連系時間設定装置３００は、出力部１１３が出力した連系開始時間を蓄電システム１毎に格納する記憶手段を備える構成であってもよい。また、連系時間設定装置３００は、連系開始時間を設定した蓄電システム１が連系を開始するまでの時間を、蓄電システム１毎に表示する表示手段を更に備える構成であってもよい。 The interconnection time setting device 300 may include a storage unit that stores the interconnection start time output by the output unit 113 for each power storage system 1.

　本実施の形態に係る電力制御システム３０の連系時間設定装置３００は、上述した第１の実施の形態と同様の効果を得ることができる。更に、電力制御システム３０の連系時間設定装置３００が、複数の蓄電システム１の夫々の連系開始時間を設定するため、各制御装置が設定する場合に比べ各蓄電システム１の連系開始時間をより異なる値に設定することができる。 (effect)
Interconnected time setting device 300 of power control system 30 according to the present embodiment can obtain the same effects as those of the first embodiment described above. Furthermore, since the connection time setting device 300 of the power control system 30 sets the connection start time of each of the plurality of power storage systems 1, the connection start time of each power storage system 1 compared to the case where each control device sets. Can be set to a different value.
　このように、ネットワークを介して蓄電システム１を制御する連系時間設定装置３００であっても、蓄電システム１の再連系時に、電力系統２の安定性を向上させることができる。 As described above, even when the grid connection time setting device 300 controls the power storage system 1 via the network, the stability of the power system 2 can be improved when the power storage system 1 is reconnected.
　したがって、本実施の形態にかかる電力制御システム３０は、例えば、ＨＥＭＳ（Ｈｏｍｅ　Ｅｎｅｒｇｙ　Ｍａｎａｇｅｍｅｎｔ　Ｓｙｓｔｅｍ）、ＢＥＭＳ（Ｂｕｉｌｄｉｎｇ　Ｅｎｅｒｇｙ　Ｍａｎａｇｅｍｅｎｔ　Ｓｙｓｔｅｍ）、ＣＥＭＳ（Ｃｌｕｓｔｅｒ／Ｃｏｍｍｕｎｉｔｙ　Ｅｎｅｒｇｙ　Ｍａｎａｇｅｍｅｎｔ　Ｓｙｓｔｅｍ）等に適用することができる。 Therefore, the power control system 30 according to the present embodiment can be applied to, for example, HEMS (Home Energy Management System), BEMS (Building Energy Management System), CEMS (Cluster / Community Energy), and the like.
　＜第５の実施の形態＞
　次に、本発明の第５の実施の形態について説明する。第４の実施の形態では、設定部１１２が、連系開始時間が蓄電システム１毎に異なるように、連系開始時間を設定することについて説明したが、これに限定されるものではない。設定部１１２は、第２の実施の形態と同様に、蓄電システム１の連系開始時間を、同じ電力系統に連系された、１以上の蓄電システム１を含む蓄電システム群毎に異なるように、且つ、１つの蓄電システム群に含まれる１以上の蓄電システム１は同じになるように、設定してもよい。 <Fifth embodiment>
Next, a fifth embodiment of the present invention will be described. In 4th Embodiment, although the setting part 112 demonstrated setting the connection start time so that connection start time might differ for every electrical storage system 1, it is not limited to this. Similarly to the second embodiment, setting unit 112 sets the connection start time of power storage system 1 to be different for each power storage system group including one or more power storage systems 1 connected to the same power system. In addition, one or more power storage systems 1 included in one power storage system group may be set to be the same.
　このように、本実施の形態に係る連系時間設定装置３００は、１以上の蓄電システム１が属する蓄電システム群毎に異なるように、且つ、同じ蓄電システム群に含まれる１以上の蓄電システム１は同じになるように、連系開始時間を設定する。これにより、同じグループ（蓄電システム群）に含まれる蓄電システム１は、同じタイミングで電力系統２に連系することができる。また、異なるグループに属する蓄電システム１は、異なるタイミングで電力系統２に連系するため、第４の実施の形態と同様に、再連系時であっても、電力系統２の安定性を向上させることができる。 As described above, the grid connection time setting device 300 according to the present embodiment is different for each power storage system group to which one or more power storage systems 1 belong, and one or more power storage systems 1 included in the same power storage system group. Set the interconnection start time so that they are the same. Thereby, the power storage systems 1 included in the same group (power storage system group) can be connected to the power system 2 at the same timing. In addition, since the power storage systems 1 belonging to different groups are linked to the power grid 2 at different timings, the stability of the power grid 2 is improved even during re-linkage, as in the fourth embodiment. Can be made.
　＜第６の実施の形態＞
　次に、本発明の第６の実施の形態について、図１０および図１１を参照して説明する。なお、説明の便宜上、前述した各実施の形態で説明した図面に含まれる部材と同じ機能を有する部材については、同じ符号を付し、その説明を省略する。 <Sixth Embodiment>
Next, a sixth embodiment of the present invention will be described with reference to FIG. 10 and FIG. For convenience of explanation, members having the same functions as the members included in the drawings described in the above-described embodiments are denoted by the same reference numerals and description thereof is omitted.
　上述した第４および第５の実施の形態における電力制御システムでは、連系開始時間が、設定部１１２によって固定的に設定されることについて説明したが、第３の実施の形態と同様に設定部１１２は、連系開始時間を都度変更するものであってもよい。 In the power control systems in the fourth and fifth embodiments described above, it has been described that the interconnection start time is fixedly set by the setting unit 112. However, the setting unit is similar to the third embodiment. 112 may change the connection start time each time.
　本実施の形態では、連系開始時間を、前記電力系統との解列後に前記電力系統からの電力供給が可能になる度に設定することについて説明する。 In the present embodiment, a description will be given of setting the interconnection start time every time power can be supplied from the power system after disconnecting from the power system.
　図１０は、本実施の形態に係る電力制御システム３０における蓄電システム１の制御装置２００、および、連系時間設定装置３００の機能構成の一例を示す機能ブロック図である。また、図１１は、制御装置２００、および、連系時間設定装置３００の処理の流れの一例を示すフローチャートである。図１１においては、制御装置２００の処理を左側に、連系時間設定装置３００の処理を右側に示している。また、制御装置２００に対するフローチャートと、連系時間設定装置３００に対するフローチャートとの間の破線の矢印は、情報の伝達を示している。 FIG. 10 is a functional block diagram showing an example of the functional configuration of the control device 200 of the power storage system 1 and the interconnection time setting device 300 in the power control system 30 according to the present embodiment. FIG. 11 is a flowchart illustrating an example of a processing flow of the control device 200 and the interconnection time setting device 300. In FIG. 11, the process of the control device 200 is shown on the left side, and the process of the interconnection time setting device 300 is shown on the right side. A broken line arrow between the flowchart for the control device 200 and the flowchart for the interconnection time setting device 300 indicates information transmission.
　なお、本実施の形態に係る連系時間設定装置３００の連系時間設定部１１０は、第４の実施の形態に係る連系時間設定部１１０と同様に、蓄電システム１毎に異なるように、連系開始時間を設定するとして説明を行うが、これに限定されるものではない。連系時間設定部１１０は、第５の実施の形態と同様に、１以上の蓄電システム１を含む蓄電システム群毎に異なるように、連系開始時間を設定してもよい。 In addition, like the interconnection time setting unit 110 according to the fourth embodiment, the interconnection time setting unit 110 of the interconnection time setting device 300 according to the present embodiment is different for each power storage system 1. Although the description will be made assuming that the interconnection start time is set, the present invention is not limited to this. Similarly to the fifth embodiment, the interconnection time setting unit 110 may set the interconnection start time so as to be different for each power storage system group including one or more power storage systems 1.
　図１０に示す通り、連系時間設定装置３００は、収集部１１１、設定部１１２および出力部１１３を備えた連系時間設定部１１０を備えている。また、制御装置２００は、制御部１０１、表示部１０２、送信部２０４および受信部２０５を備えている。また、制御装置２００は、記憶部１０３を更に備える構成であってもよい。 As shown in FIG. 10, the interconnection time setting device 300 includes an interconnection time setting unit 110 including a collection unit 111, a setting unit 112, and an output unit 113. The control device 200 includes a control unit 101, a display unit 102, a transmission unit 204, and a reception unit 205. The control device 200 may further include a storage unit 103.
　本実施の形態に係る制御装置２００と、第４の実施の形態に係る制御装置２００との異なる点は、制御部１０１から送信部２０４に対して、信号を送信する点である。以下では、図１０の各部の処理を、図１１のフローチャートを参照しながら説明する。なお、図１１では、蓄電システム１が電力系統２と連系していない状態（解列通知を受信した後の状態）であることを前提に説明を行う。 The difference between the control device 200 according to the present embodiment and the control device 200 according to the fourth embodiment is that a signal is transmitted from the control unit 101 to the transmission unit 204. Hereinafter, the processing of each unit in FIG. 10 will be described with reference to the flowchart in FIG. 11. In addition, in FIG. 11, it demonstrates on the assumption that the electrical storage system 1 is a state (state after receiving disconnection notification) which is not connected with the electric power grid | system 2. FIG.
　図１１に示す通り、まず、制御装置２００の制御部１０１が、復電を検知したスイッチ部１１から復電通知を受信する（ステップＳ１１１）と、復電タイマのカウントを開始する（ステップＳ１１２）。また、制御部１０１は、連系時間設定装置３００に対し、復電通知を受信したことを示す信号を送信部２０４に送信する。なお、制御部１０１は、この信号の送信とステップＳ１１２とを同時に行ってもよい。 As shown in FIG. 11, first, when the control unit 101 of the control device 200 receives a power recovery notification from the switch unit 11 that has detected power recovery (step S111), it starts counting a power recovery timer (step S112). . In addition, the control unit 101 transmits a signal indicating that the power recovery notification has been received to the transmission time setting device 300 to the transmission unit 204. Note that the control unit 101 may perform the transmission of this signal and step S112 at the same time.
　送信部２０４は、復電通知を受信したことを示す信号を受信すると、自システムの固有の情報と、予め電力会社等によって設定された連系開始時間の最小値および最大値を示す情報とを連系時間設定装置３００に送信する（ステップＳ１１３）。 When receiving the signal indicating that the power recovery notification has been received, the transmission unit 204 receives information specific to its own system and information indicating the minimum value and the maximum value of the interconnection start time set in advance by the power company or the like. It transmits to the interconnection time setting device 300 (step S113).
　連系時間設定装置３００の収集部１１１は、制御装置２００から送信された、蓄電システム１の固有の情報等を受信する（ステップＳ１１４）。これにより、収集部１１１は、連系開始時間の算出に用いる、蓄電システム１の固有の情報と、予め電力会社等によって設定された連系開始時間の最小値および最大値を示す情報とを収集する。 The collection unit 111 of the grid connection time setting device 300 receives information unique to the power storage system 1 transmitted from the control device 200 (step S114). Thereby, the collection unit 111 collects information specific to the power storage system 1 used for calculation of the grid connection start time and information indicating the minimum value and the maximum value of the grid connection start time set in advance by an electric power company or the like. To do.
　そして、連系時間設定装置３００の設定部１１２は、入力情報に応じて、連系開始時間を算出し（ステップＳ１１５）、算出結果を、情報を送信した蓄電システム１の連系開始時間として設定する（ステップＳ１１６）。そして、出力部１１３は、設定部１１２が設定した連系開始時間を、連系開始時間を設定した蓄電システム１の制御装置２００に送信する。 Then, the setting unit 112 of the interconnection time setting device 300 calculates the interconnection start time according to the input information (step S115), and sets the calculation result as the interconnection start time of the power storage system 1 that transmitted the information. (Step S116). Then, the output unit 113 transmits the interconnection start time set by the setting unit 112 to the control device 200 of the power storage system 1 that sets the interconnection start time.
　次に、制御装置２００の受信部２０５は、連系時間設定装置３００から連系時間設定装置３００が設定した連系開始時間を受信し（ステップＳ１１７）、制御部１０１に受信した連系開始時間を送信する。なお、受信部２０５は、受信した連系開始時間を、記憶部１０３に格納してもよい。 Next, the receiving unit 205 of the control device 200 receives the interconnection start time set by the interconnection time setting device 300 from the interconnection time setting device 300 (step S117), and the interconnection start time received by the control unit 101. Send. Note that the receiving unit 205 may store the received interconnection start time in the storage unit 103.
　制御装置２００の制御部１０１は、カウントが設定時間（連系開始時間）になったか否かを確認する（ステップＳ１１８）。そして、制御部１０１は、カウントが設定時間でないとき（ステップＳ１１８にてＮＯ）に、停電通知を受信したか否かを確認する（ステップＳ１１９）。停電通知を受信していない場合（ステップＳ１１９にてＮＯ）、制御部１０１は、処理をステップＳ１１８に戻す。 The control unit 101 of the control device 200 confirms whether the count has reached a set time (interconnection start time) (step S118). Then, control unit 101 checks whether or not a power failure notification is received when the count is not the set time (NO in step S118) (step S119). If a power failure notification has not been received (NO in step S119), control unit 101 returns the process to step S118.
　停電通知を受信した場合（ステップＳ１１９にてＹＥＳ）、制御部１０１は、カウントをクリアする（ステップＳ１２０）。そして、制御部１０１は、復電を検知したスイッチ部１１から復電通知を受信する（ステップＳ１２１）と、再度、復電タイマのカウントを開始する（ステップＳ１２２）。そして、制御部１０１は、処理をステップＳ１１８に戻す。 When a power failure notification is received (YES in step S119), control unit 101 clears the count (step S120). Then, when the control unit 101 receives a power recovery notification from the switch unit 11 that has detected power recovery (step S121), the control unit 101 starts counting the power recovery timer again (step S122). Then, the control unit 101 returns the process to step S118.
　カウントが設定時間となったとき（ステップＳ１１８にてＹＥＳ）、制御部１０１は、スイッチ部１１に連系指示を送信する（ステップＳ１２３）。 When the count reaches the set time (YES in step S118), the control unit 101 transmits an interconnection instruction to the switch unit 11 (step S123).
　連系指示を受け取ったスイッチ部１１は、スイッチを閉じて、蓄電システム１を電力系統２に連系させる。これにより、蓄電システム１は、電力系統２に連系することができる。 The switch unit 11 that has received the interconnection instruction closes the switch to link the power storage system 1 to the power system 2. Thereby, the power storage system 1 can be linked to the power system 2.
　本実施の形態では、スイッチが開放された状態において、停電通知を受信した（ステップＳ１１９）後に、復電通知を受信した（ステップＳ１２１）場合、制御部１０１は、ステップＳ１１４～Ｓ１１６の連系時間設定処理で設定された連系開始時間を復電タイマの設定時間として用いた。しかし、制御装置２００は、ステップＳ１２２の後に、ステップＳ１１１に処理を戻し、再度連系開始時間を設定する処理を行ってもよい。つまり、本実施の形態に係る電力制御システム３０は、蓄電システム１が電力系統２に連系後、解列した後毎に連系開始時間を設定してもよいし、スイッチ部１１のセンサが所定の値を超えた電圧を検知したとき毎に、連系開始時間を設定してもよい。 In the present embodiment, when the power recovery notification is received (step S121) after the power failure notification is received (step S119) in a state where the switch is opened, the control unit 101 performs the interconnection time of steps S114 to S116. The grid connection start time set in the setting process was used as the power recovery timer setting time. However, the control device 200 may return the process to step S111 after step S122 and perform the process of setting the interconnection start time again. That is, the power control system 30 according to the present embodiment may set the connection start time every time after the power storage system 1 is connected to the power system 2 and disconnected, or the sensor of the switch unit 11 The interconnection start time may be set every time a voltage exceeding a predetermined value is detected.
　このとき、設定部１１２は、連系開始時間が電力制御システム３０に含まれる複数の蓄電システム１毎に異なるように、且つ、前回に算出した値と異なるように、連系開始時間を算出する。このとき、所定の関数に入力する情報として、蓄電システム１の設定情報のように固定の情報だけでなく、該制御装置２００が前回算出した連系開始時間を用いることが好ましい。また、所定の関数に入力する情報として、現在時刻であってもよい。これにより、例えば、所定の関数が、入力が同じものは同じ結果を出力するような関数であっても、所定の関数に入力する情報が算出する度に変更されるため、設定部１１２は、異なる結果を出力することができる。 At this time, the setting unit 112 calculates the interconnection start time so that the interconnection start time is different for each of the plurality of power storage systems 1 included in the power control system 30 and is different from the previously calculated value. . At this time, it is preferable to use not only fixed information like the setting information of the power storage system 1 but also the interconnection start time previously calculated by the control device 200 as information to be input to the predetermined function. Moreover, the current time may be used as information input to a predetermined function. Thus, for example, even if the predetermined function is a function that outputs the same result if the input is the same, the setting unit 112 is changed every time information input to the predetermined function is calculated. Different results can be output.
　（効果）
　本実施の形態に係る電力制御システム３０によれば、第４の実施の形態と同様に、蓄電システム１の再連系時であっても、電力系統２の安定性を向上させることができる。 (effect)
According to the power control system 30 according to the present embodiment, the stability of the power system 2 can be improved even when the power storage system 1 is reconnected, as in the fourth embodiment.
　また、本実施の形態に係る電力制御システム３０は、第３の実施の形態に係る電力制御システム１０と同様に、各蓄電システム１に対する公平性をより高めることができる。 Moreover, the power control system 30 according to the present embodiment can further improve the fairness with respect to each power storage system 1, similarly to the power control system 10 according to the third embodiment.
　＜第７の実施の形態＞
　本発明の第７の実施の形態について説明する。本実施の形態では、本発明の課題を解決する最小の構成について説明を行う。 <Seventh embodiment>
A seventh embodiment of the present invention will be described. In this embodiment, a minimum configuration that solves the problems of the present invention will be described.
　図１２は、本実施の形態に係る連系時間設定装置４００の機能構成の一例を示す機能ブロック図である。図１２に示す通り、本実施の形態に係る連系時間設定装置４００は、設定部１１２と、出力部１１３とを備えている。本実施の形態に係る連系時間設定装置４００は、上述した各実施の形態における連系時間設定部１１０に相当する。 FIG. 12 is a functional block diagram showing an example of a functional configuration of the interconnection time setting device 400 according to the present embodiment. As shown in FIG. 12, interconnection time setting apparatus 400 according to the present embodiment includes setting unit 112 and output unit 113. Interconnection time setting apparatus 400 according to the present embodiment corresponds to interconnection time setting unit 110 in each of the above-described embodiments.
　設定部１１２は、電力系統に連系可能な複数の蓄電システムの夫々が、電力系統との解列後に該電力系統における電力供給が可能になった時点から、連系を開始するまでの時間を示す連系開始時間を、蓄電システム、または、蓄電システム群に含まれる蓄電システムに設定する。蓄電システム群は、１以上の蓄電システムを含んでいる。設定部１１２は、この連系開始時間を、蓄電システム毎、または、蓄電システム群毎に異なるように設定する。 The setting unit 112 sets a time period from when each of the plurality of power storage systems that can be connected to the power system becomes able to supply power in the power system after being disconnected from the power system until the start of the connection. The indicated grid connection start time is set for the power storage system or the power storage system included in the power storage system group. The power storage system group includes one or more power storage systems. The setting unit 112 sets the grid connection start time to be different for each power storage system or each power storage system group.
　出力部１１３は、設定部１１２が設定した連系開始時間を連系時間設定装置４００の出力として出力する。 The output unit 113 outputs the interconnection start time set by the setting unit 112 as an output of the interconnection time setting device 400.
　電力系統に連系可能な複数の蓄電システムの夫々は、電力系統との解列後に該電力系統における電力供給が可能になった時点から、設定された連系開始時間経過後に、電力系統に連系することができる。この連系開始時間は、蓄電システム毎、または、蓄電システム群毎に異なるように設定されているため、連系開始時間が固定的に設定されていた場合と比べ、一度に多数の蓄電システムが連系することを防ぐことができる。これにより、本実施の形態に係る連系時間設定装置４００は、再連系時であっても、電力系統の安定性を向上させることができる。 Each of the plurality of power storage systems that can be connected to the power grid is connected to the power grid after the set grid connection start time elapses from when power supply to the power grid becomes possible after disconnecting from the power grid. Can be used. Since this grid connection start time is set to be different for each power storage system or each power storage system group, compared to the case where the grid connection start time is fixedly set, a large number of power storage systems are It is possible to prevent interconnection. Thereby, interconnection time setting device 400 according to the present embodiment can improve the stability of the power system even during re-interconnection.
　なお、この連系時間設定装置４００は、蓄電システムに備えられるものであってもよい。また、連系時間設定装置４００は、蓄電システムを、ネットワークを介して制御する装置であってもよい。 Note that this interconnection time setting device 400 may be provided in the power storage system. In addition, interconnection time setting device 400 may be a device that controls the power storage system via a network.
