To optimize the total efficiency of the charge/discharge efficiency of a storage battery and the power conversion efficiency of a power conversion device.SOLUTION: A controller controls charge and discharge of each of a plurality of storage battery systems according to at least one of operation purposes. Each of the plurality of storage battery systems includes a storage battery and a power conversion device connected with the storage battery. At least one of operation purposes includes a first operation purpose of charging and discharging each of the plurality of storage battery systems so that the operation efficiency of each of the plurality of storage battery systems increases. The operation efficiency is the whole efficiency of the charge/discharge efficiency of the storage battery and the power conversion efficiency of the power conversion device against charge/discharge power.SELECTED DRAWING: Figure 1 【課題】蓄電池の充放電効率及び電力変換装置の電力変換効率の全体の効率を最適化する。【解決手段】コントローラは、少なくとも１つの運転目的に従って、複数の蓄電池システムそれぞれを充放電制御するコントローラであって、複数の蓄電池システムそれぞれは、蓄電池、及び、当該蓄電池に接続された電力変換装置を含み、少なくとも１つの運転目的は、複数の蓄電池システムそれぞれの動作効率が高くなるように複数の蓄電池システムそれぞれを充放電させる第１の運転目的を含み、動作効率は、充放電電力に対する蓄電池の充放電効率及び電力変換装置の電力変換効率の全体の効率である。【選択図】図１
