Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/211940
Kind Code:
A1
Abstract:
A solar battery power conversion device (2) is disposed between a solar battery (1) and a home power distribution system (10). A storage battery power conversion device (4) is disposed between a storage battery (3) and the home power distribution system (10). When the AC effective voltage of the home power distribution system (10) is deviated from a voltage range that is specified in accordance with dead zone information transmitted from a HEMS (7), system-voltage stabilizing control for restoring the AC effective voltage into the voltage range is performed through control of effective power and ineffective power outputted from a first DC/AC conversion circuit (208) and a second DC/AC conversion circuit (408).
