To provide an interconnection control system capable of preventing interruption of power supply when power is restored, an interconnection control device, and a system interconnection method.SOLUTION: A system interconnection system with a power system includes: a storage battery; a power conversion device for converting power from a storage battery into AC; and an interconnection control device for supplying power from a commercial power supply to a load and supplying power from the power conversion device to the load when the commercial power supply fails. When the commercial power is restored, the interconnection control device starts power supply from the commercial power supply to the load. After starting the power supply from the commercial power supply to the load, the power supply from the power conversion device to the load is stopped.SELECTED DRAWING: Figure 2

    【課題】復電時に電力供給を中断させないようにすることができる系統連系システム、連系制御装置及び系統連系方法を提供する。【解決手段】電力系統との系統連系システムは、蓄電池と、該蓄電池からの電力を交流へ変換する電力変換装置と、商用電源から負荷へ電力を供給し、前記商用電源が停電した場合に前記電力変換装置から前記負荷へ電力を供給する連系制御装置とを備える。前記連系制御装置は、前記商用電源が復電した場合に、前記商用電源から前記負荷への電力供給を開始し、前記商用電源から前記負荷への電力供給の開始後に、前記電力変換装置から前記負荷への電力供給を停止する。【選択図】図2
