To provide a power system for performing energy management including charge/discharge control of an electric automobile.SOLUTION: A power system S1 comprises: a detection device C1 which detects a value of junction power; a processing device A1 which derives an induction command value for setting the value of the junction power to a set adjustment target value; and a plurality of power control devices B1 each of which is electrically connected with a junction K and controls output power on the basis of an optimization problem using the induction command value. Each of the plurality of power control devices B1 comprises: a charge/discharge control device 10 for a storage battery with which a storage battery 19 is connected; and a charge/discharge control device 20 for an EV with which an electric automobile 29 can be connected. When a communication abnormality occurs in any of communication between the detection device C1 and the processing device A1, communication between the processing device A1 and the charge/discharge control device 10 for the storage battery, and communication between the processing device A1 and the charge/discharge control device 20 for the EV, the charge/discharge control device 20 for the EV notifies that the communication abnormality occurs while stopping charge/discharge of the electric automobile 29.SELECTED DRAWING: Figure 1 【課題】電気自動車の充放電制御を含めたエネルギー管理を行う電力システムを提供する。【解決手段】電力システムＳ１は、接続点電力の値を検出する検出装置Ｃ１と、接続点電力の値を設定された調整目標値にするための誘導指令値を導出する処理装置Ａ１と、各々が、接続点Ｋに電気的に接続されかつ誘導指令値を用いた最適化問題に基づいて、出力電力を制御する複数の電力制御装置Ｂ１と、を備える。複数の電力制御装置Ｂ１は、蓄電池１９が接続された蓄電池用充放電制御装置１０と電気自動車２９を接続可能なＥＶ用充放電制御装置２０とを含む。検出装置Ｃ１と処理装置Ａ１との間の通信、処理装置Ａ１と蓄電池用充放電制御装置１０との間の通信、および、処理装置Ａ１とＥＶ用充放電制御装置２０との間の通信のいずれかにおいて通信異常が生じたときに、ＥＶ用充放電制御装置２０は、電気自動車２９の充放電を停止しつつ、通信異常が生じていることを報知する。【選択図】図１
