DISTRIBUTED POWER SOURCE SYSTEM WITH STORAGE BATTERY

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