Abstract: A power control apparatus for a distributed power supply interconnected with a power system includes: a conversion circuit that performs reverse conversion of converting power supplied from the distributed power supply from direct current to alternating current and outputting the converted power; and a control device that controls the conversion circuit. The control device changes a target value of received power at a power reception point of the power system on the basis of a predicted value of a power generation amount of the distributed power supply and a predicted value of power consumption of a demand facility, and controls an output of the conversion circuit such that the received power at the power reception point becomes a target value.
