Abstract
A power conversion device includes a second DC/AC conversion circuit. The second DC/AC conversion circuit operates as a voltage source for an AC grid based on a command notified from an external controller to a communication interface. A fourth control circuit generates phase information of the grid AC voltage based on an actually measured value of a grid AC voltage output from the second DC/AC conversion circuit to a power distribution grid, and calculates a target AC voltage in a shape of a sinusoidal wave using a frequency command value of the grid AC voltage from the outside and the generated phase information. The fourth control circuit controls an operation of the second DC/AC conversion circuit to compensate for a deviation between the actually measured value of the grid AC voltage and the target AC voltage.
