Abstract

In an electric power system interconnection device, a primary power supply is connected to a load via a switch and a secondary power supply is connected to a load side of the load via a power converter to establish coordinated interconnection of the primary power supply and the secondary power supply. When the switch is opened in the event of a failure of the primary power supply, the electric power system interconnection device extinguishes an arc current flowing through the switch, at a high speed, by controlling an output current of the power converter using the load current flowing into the load as an output current command for the power converter so that uninterrupted electric power is supplied to the load.
