Abstract
This power control system () includes a power generation apparatus () that generates, while a current sensor () detects forward power flow equal to or greater than a threshold, power corresponding to a value detected by the current sensor, and a power control apparatus () that controls distributed power sources. The power control apparatus is connected to a dummy current output unit capable of supplying the current sensor with dummy current. The control method includes, in a state of constant current flowing to a load from the power generation apparatus and the power control apparatus for a predetermined time, a first step of the power control apparatus increasing the dummy current from the dummy current output unit stepwise, and after the first step, a second step of storing, as the threshold, a minimum of the forward power flow when output voltage of the power generation apparatus rises.
