Zusammenfassung:To avoid imbalance in the entire BG by addressing fluctuation in a renewable energy power generation amount after GC and executing storage battery control with consideration given to a communication delay.SOLUTION: This imbalance avoidance device comprises: one or more renewable energy power sources; and a control unit provided for a BG including a plurality of storage batteries. The control unit includes: an instruction value generation unit that generates an instruction value regarding a charging/discharging amount for each storage battery so as to minimize imbalance between BG power generation and demand at prescribed unit time on the basis of a power generation amount prediction value at prescribed unit time for each renewable energy power source, a power generation achievement value until current time at prescribed unit time for each renewable energy power source, a charging/discharging achievement value for each storage battery, communication delay time indicating delay time from an instruction for each storage battery to an operation start, and a power generation plan presented to a wide-area institution; and a system control unit that controls each storage battery on the basis of the instruction value.SELECTED DRAWING: Figure 8 【課題】GC後の再生可能エネルギー発電量の変動に対応するとともに、通信遅延を考慮した蓄電池制御を行うことによって、BG全体でインバランスを回避する。【解決手段】実施形態のインバランス回避装置は、1以上の再生可能エネルギー電源、および、複数の蓄電池を有するBGに対して設けられる制御部を備える。制御部は、再生可能エネルギー電源ごとの所定単位時間における発電量予測値と、再生可能エネルギー電源ごとの所定単位時間における現在までの発電量実績値と、蓄電池ごとの充放電量実績値と、蓄電池ごとの指示から動作開始までの遅延時間を示す通信遅延時間と、広域機関に提出した発電計画と、に基づいて、所定単位時間におけるBGの発電と需要のインバランスを最小にするように蓄電池ごとの充放電量に関する指示値を作成する指示値作成部と、指示値に基づいて蓄電池を制御するシステム制御部と、を有する。【選択図】図8
