Title:
POWER CONVERSION SYSTEM AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/144841
Kind Code:
A1
Abstract:
This power conversion device (50) comprises: a power conversion circuit (550) which converts DC power output from a distributed power source into AC power, and outputs the AC power to a power distribution system; a voltage target value generation unit (520) which removes high-frequency fluctuations from the effective value of the voltage detected by a voltage detection unit (510) and generates a voltage target value (Vref); a correction unit which corrects the voltage target value (Vref), when an automatic voltage regulator is detected to be operated; and a command unit which, when a voltage at an interconnection point detected by the voltage detection unit deviates from a voltage control dead zone based on the voltage target value, commands the power conversion circuit to output reactive power according to the magnitude of the deviated voltage.
