Original Abstract Submitted
a virtual synchronous generator controller included in a controller of a power convertor generates a first command value of a frequency of a second voltage and a second command value of a phase of the second voltage by making an active power value and an active power target value correspond respectively to electrical energy and mechanical energy of a motion equation of a rotor of a synchronous generator to simulate an operation of the synchronous generator. when a turn-on condition is satisfied, a determination unit switches a connection state from a non-conduction state to a conduction state by controlling a relay that causes the connection state between an inverter and an ac power system to be selectively switched between the conduction state and the non-conduction state.
