Abstract
A power conversion device includes a power converter and a control device. The power converter converts a DC power output from a power storage element into an AC power. The control device includes a phase synchronizing unit to estimate a reference phase of an output voltage of the power converter synchronized with a phase of an AC voltage at an interconnection point, a characteristics simulating unit to generate an active power command value based on a phase difference between a reference phase and the phase of the AC voltage at the interconnection point, a DC voltage command generating unit to generate a DC voltage command value, a voltage command generating unit to generate an AC voltage command value so that an output current of the power converter becomes less than a threshold, and a signal generating unit to generate a control signal based on the AC voltage command value.
