PROBLEM TO BE SOLVED: To provide a power storage control system that can perform stabilization of a system simple and at low cost in a power storage control system in which a power generation system using renewable energy is connected to a power storage system.SOLUTION: A power storage control system comprises a power conversion device for renewable energy, a power conversion device for power storage, a disconnecting device for interconnecting or disconnecting them to and from an electric power system, and a control device for controlling them. The control device charges generated power generated by a renewable energy generator while a disconnecting device is disconnected, into a storage battery connected to the power conversion device for power storage via the power converting device for renewable energy. Power from the renewable energy power generator or power from the storage battery is supplied to the power system via the power conversion device for renewable energy or the power conversion device for power storage under the state that the disconnecting device is interconnected.SELECTED DRAWING: Figure 1 【課題】再生可能エネルギーを利用した発電システムと蓄電システムを接続した蓄電制御システムにおいて、簡単かつ低コストで系統の安定化を実現することを目的とする。【解決手段】蓄電制御システムであって、再生可能エネルギー用電力変換装置と、蓄電用電力変換装置と、それらを電力系統に連系若しくは解列させる解列装置と、それらを制御する制御機器とを有し、制御機器は、解列装置を解列した状態で再生可能エネルギー発電装置で発電した発電電力を再生可能エネルギー用電力変換装置を介して蓄電用電力変換装置に接続された蓄電池に充電し、解列装置を連系した状態で再生可能エネルギー発電装置からの電力若しくは蓄電池からの電力を再生可能エネルギー用電力変換装置または蓄電用電力変換装置を介して電力系統に供給するように構成する。【選択図】図１
