Summary:To provide a power system in which management targets of a centralized management device can be expanded to a power device the input/output power of which cannot be controlled, and a switching device that is used for the power system.SOLUTION: A switching device A performs switching between a conductive state in which a power device B is carrying out power reception and power transmission with respect to a power grid E, and a non-conductive state in which neither the power reception nor the power transmission is being carried out. The switching device A includes: a determination index calculation unit 111 that calculates a determination index X for determining whether to set the power device B to the conductive state or the non-conductive state on the basis of an induction index pr inputted from a centralized management device F managing the switching device A and a preset optimization problem; and a comparison unit 112 that performs switching between the conductive state and the non-conductive state on the basis of a comparison result obtained by a comparison of the determination index X with a prescribed value.SELECTED DRAWING: Figure 1 【課題】集中管理装置による管理対象を入出力電力を制御できない電力装置まで拡張できる電力システム、および、当該電力システムに用いられる切替装置を提供する。【解決手段】電力装置Ｂが電力系統Ｅから受電または送電を行っている状態である通電状態と、受電および送電を行っていない状態である不通状態とを切り替える切替装置Ａにおいて、切替装置Ａを管理する集中管理装置Ｆから入力される誘導指標ｐｒと、あらかじめ設定されている最適化問題とに基づいて、電力装置Ｂを通電状態とするか不通状態とするかを判断するための判断指標Ｘを算出する判断指標演算部１１１と、判断指標Ｘを所定値と比較した比較結果に基づいて、通電状態と不通状態とを切り替える比較部１１２とを備えた。【選択図】図１
