At least one of a plurality of generators is a first generator configured such that a relationship of a generator output voltage with respect to a generator active power output from the generator to a corresponding first AC wiring portion has a predetermined first drooping characteristic. The control device is configured to generate a drive signal for a power conversion device by deciding a target value of a first control element such that a relationship of an AC wiring portion voltage with respect to a power conversion device active power output from the power conversion device to a first AC wiring portion corresponding to a first generator has a predetermined second drooping characteristic and correcting the target value of the first control element according to a DC voltage at a DC wiring portion.

Power supply system

Each of the plurality of generators is configured so a relationship of frequency with respect to a generator active power output by each generator to the corresponding alternating-current wiring unit has a predetermined first drooping characteristic. The plurality of power conversion devices is configured to convert alternating-current power input through each alternating-current wiring unit into direct-current power, and to convert direct-current power input through the direct-current wiring unit into alternating-current power. The control device is configured to determine a target value of a control element such that a relationship of frequency with respect to a power conversion device active power output by each power conversion device to the corresponding alternating-current wiring unit has a predetermined second drooping characteristic, and is configured to generate a drive signal for each power conversion device by correcting a target value of the control element in response to direct-current voltage at the direct-current wiring unit.
