Title: POWER SUPPLY SYSTEM
Abstract:
According to the present invention: each of a plurality of power generators is configured so that a frequency relationship with power-generator effective power that is output to a corresponding AC wiring section by each of the power generators has a prescribed first drooping characteristic; a plurality of power conversion devices are configured to convert, into DC power, AC power that is input through each of the AC wiring sections and to convert, into AC power, DC power that is input through a DC wiring section; and control devices are configured to determine a target value of a control factor so that a frequency relationship with power-conversion-device effective power that is output to the corresponding AC wiring section by each of the power conversion devices has a prescribed second drooping characteristic and to generate a driving signal for each of the power conversion devices by correcting the target value of the control factor according to a DC voltage in the DC wiring section.
