  • Publication number: 20250047214
    Abstract: A power conversion device is disclosed in which a first command to change amplitude and phase of AC-power by grid forming control (GFM) is generated. A second command to change amplitude and phase of the AC-power by grid following control (GFL) is generated. A modulation circuit changes amplitude and phase of the AC-power in response to the first or second command. The first command is corrected before input to the modulation circuit is switched from the second command to the first command such that a difference between target amplitude of the first command and amplitude of a given grid voltage becomes a threshold or smaller, a difference between target frequency of the first command and frequency of the grid voltage becomes a threshold or smaller, and a difference between target phase of the first command and phase of the grid voltage becomes a threshold or smaller.
