To provide a power management system capable of properly suppressing voltage fluctuation in a power system and voltage fluctuation in a microgrid according to the situation.SOLUTION: A power management system 100 further includes: a CEMS server 2 that manages a charging facility 17 in a microgrid MG; and a transmission and distribution operator server 5 that manages the power supply and demand balance in a power system 4. The charging facility 17 is configured so as to execute a charge/discharge operation to suppress voltage fluctuation in the microgrid MG by exchanging the power between the microgrid MG and a vehicle 18 and a reactive power compensation operation to suppress voltage fluctuation in the power system 4 by controlling the reactive power in the microgrid MG. The charging facility 17 executes a charge/discharge operation in response to a request from the CEMS server 2 when the vehicle 18 is electrically connected to the charging facility 17, and when the vehicle 18 is not electrically connected to the charging facility 17, executes a reactive power compensation operation in response to a request from the transmission and distribution operator server 5.SELECTED DRAWING: Figure 3

    【課題】電力系統の電圧変動およびマイクログリッドの電圧変動を状況に応じて適切に抑制する。【解決手段】電力管理システム100は、マイクログリッドMG内の充電設備17を管理するCEMSサーバ2と、電力系統4の電力需給バランスを管理する送配電事業者サーバ5とをさらに備える。充電設備17は、マイクログリッドMGと車両18との間で電力をやり取りすることでマイクログリッドMGの電圧変動を抑制する充放電動作と、マイクログリッドMGの無効電力を制御することで電力系統4の電圧変動を抑制する無効電力補償動作とを実行可能に構成されている。充電設備17は、車両18が充電設備17に電気的に接続されている場合、CEMSサーバ2からの要求に応答して充放電動作を実行する一方で、車両18が充電設備17に電気的に接続されてない場合には、送配電事業者サーバ5からの要求に応答して無効電力補償動作を実行する。【選択図】図3
