Abstract: A management or control of a power router is more appropriately performed when a power network system in which power cells are asynchronously connected with each other. A plurality of power conversion legs bi-directionally convert power, one ends thereof are connected with a direct current bus and the other ends thereof are connected with an external connection partner as an external connection terminal. A control unit controls operations of the plurality of power conversion legs. The control unit receives a control instruction including a designation of a stopping target leg. The control unit performs an adequacy determination of whether the stopping target leg can be stopped. The control unit stops the stopping target leg when the stopping target leg can be stopped.

Abstract: A control or management of a power router is more adequately performed when constructing a power network system in which power cells are asynchronously connected with each other. The power network system includes a first power router, a second power router and a management server. The first power router transmits power. The second power router receives the power from the first power router and the obtain information indicating the received power. The management server controls the power transmitted by the first power router base on the information indicating the received power.

Abstract: The purpose of the present invention is to enable a power router to be more suitably managed or controlled when constructing a power network system in which power cells are asynchronously interconnected. A power router has a first master leg, a second master leg, a first stand-alone leg, and a second stand-alone leg. Based on the power transmitted and received by the first stand-alone leg and the second stand-alone leg, a control unit controls the power transmitted and received by the first master leg and the power transmitted and received by the second master leg.

Abstract: A management or control of a power router is more appropriately performed when a power network system in which power cells are asynchronously connected with each other. A plurality of power conversion legs bi-directionally convert power, one ends thereof are connected with a direct current bus and the other ends thereof are connected with an external connection destination as an external connection terminal. A control unit controls operations of the plurality of power conversion legs. The control unit receives a control instruction including a designation of an activation target leg and a designation of an operation mode of the activation target leg. The control unit determines whether the activation target leg can be activated in a designated operation mode. The control unit activates the activation target leg in the designated operation mode when the activation target leg can be activated in the designated operation mode.
