Document Type and Number:
WIPO Patent Application WO/2019/078184
Kind Code:
A1
Abstract:
At least one of a plurality of generators is a first generator configured such that the relationship of generator output voltage to generator active power has a predetermined first drooping characteristic, said generator active power being output to a corresponding first AC wiring portion by the one of the plurality of generators. A plurality of power conversion devices are configured to convert AC power, which is input through the respective AC wiring portions, to DC power and convert DC power, which is input through a DC wiring portion, to AC power. A control device is configured to determine the target value of a first control element so that the relationship of AC wiring portion voltage to power conversion device active power has a predetermined second drooping characteristic, said power conversion device active power being output to the first AC wiring portion corresponding to the first generator by the power conversion device, and to generate a drive signal for the power conversion device by correcting the target value of the first control element in accordance with DC voltage in the DC wiring portion.
