Abstract
A power conversion device is disclosed in which a grid following amplitude command value and a grid following phase command value are output in response to receiving a switching signal instructing switching from grid following control to grid forming control. The grid following amplitude command value indicates a target value of an amplitude computed by the grid following control. The grid following phase command value indicates a target value of a phase computed by the grid following control. When the grid following control is switched to the grid forming control, an initial value of the target value of the amplitude in the grid forming control to be the grid following amplitude command value is set, and an initial value of the target value of the phase in the grid forming control to be the grid following phase command value is set.
