Abstract
The present system 1 includes a distributed power source 2, a storage battery 4, a bidirectional inverter 7 having a smoothing capacitor 6 on its DC side, and a control section 10 for controlling the entire system, and supplies AC power to a load 9 while being interconnected with a power system 8. When active power supplied from the distributed power source 2 and/or the storage battery 4 to the smoothing capacitor 6 is equal to or greater than active power of load power, the control section 10 controls a power factor of inverter output current outputted from the bidirectional inverter 7 so as to coincide with a power factor of load current flowing to the load 9.
