Abstract
In the case of performing self-sustained operation, when power conversion devices supply power to loads, all DC/AC conversion circuits of the power conversion devices are operated in a voltage control mode, and effective voltage (amplitude) of reference AC voltage as a control target for AC power outputted from each DC/AC conversion circuit under voltage control is adjusted in accordance with the power generation amount of a solar panel as a DC power supply, and the state of charge of a storage battery, thereby the amount of power supplied to the loads is controlled.
