To perform flexible power supply management.SOLUTION: A power system S includes a stationary power supply 10, a power conversion device 30 for converting power of the stationary power supply 10, one or a plurality of chargers/dischargers 100 connected in parallel with the power conversion device 30, and a power control device 50 for controlling the power conversion device 30. The power conversion device 30 interconnects with a power system 1 via an interconnection line L0 and the chargers/dischargers 100 are for mobile bodies. The power control device 50 has two operation modes of a first operation mode and a second operation mode. The power control device 50 controls only an amount of electricity of the stationary power supply 10 in the first operation mode and controls an amount of electricity of a power supply 230 mounted on a mobile body 200 connected to a charger/discharger 100 in addition to the amount of electricity of the stationary power supply 10 in the second operation mode.SELECTED DRAWING: Figure 1

    【課題】柔軟性のある電源マネージメントを行う。【解決手段】電力システムSは、定置電源10と、前記定置電源10の電力を変換する電力変換装置30と、前記電力変換装置30と並列に接続された、1又は複数の充放電器100と、前記電力変換装置30を制御する電力制御装置50と、を含み、前記電力変換装置30は、連系線L0を介して電力系統1に連系し、前記充放電器100は、移動体用である。前記電力制御装置50の運転モードには、第1運転モードと第2運転モードの2つの運転モードがある。前記電力制御装置50は、前記第1運転モードにおいて、前記定置電源10の電気量のみ制御し、前記第2運転モードにおいて、前記定置電源10の電気量に加え、前記充放電器100に接続された移動体200の搭載電源230の電気量を制御する。【選択図】図1
