Abstract

See full text

A power conversion device includes a converter, an inverter, a converter control circuit, a virtual synchronous generator control circuit to impart a transient characteristic of a synchronous generator to the inverter, and an inverter control circuit to control the inverter. The virtual synchronous generator control circuit calculates a switching frequency at which charge/discharge of the distributed power source is switched, based on information necessary for virtual synchronous generator control. The converter control circuit uses the switching frequency to create a frequency range of AC system voltage for providing a dead zone in which charge/discharge power of the distributed power source is zero in a drooping characteristic of the power conversion device, or a hysteresis in switching of charge/discharge of the distributed power source. The converter control circuit performs control such that charge/discharge power of the distributed power source becomes zero in the frequency range.
