A first power converter selectively performs a charging operation to convert a portion of first alternating-current power received from a power system to direct-current power and store the direct-current power in a power storage device, and a discharging operation to convert direct-current power of the power storage device to second alternating-current power. When the power system is healthy, a controller controls the charging operation so that the power storage device is fully charged. When a demand response preannouncement signal is received from a server, the controller controls the discharging operation to supply the load with a total power of the first alternating-current power and the second alternating-current power, and stops the discharging operation in response to the power storage device having an SOC reduced to a standby SOC. The controller controls the discharging operation or the charging operation in response to a demand response command received from the server.
