Abstract
An inverter converts power outputted from a distributed power supply into AC power, and outputs to an AC system. An inverter control circuit generates an AC voltage target value at a time of controlling the inverter, and generates a command value for control of the inverter as a voltage source. When the inverter is introduced into the AC system, the inverter control circuit sets a frequency of the AC voltage target value to a frequency of an AC voltage detected by an AC frequency detection circuit, and controls a phase of the AC voltage target value to be at least a leading phase with respect to the AC voltage of the AC system when a target value of the AC power is in a running direction.
