WIPO Patent Application WO/2021/079554

A1

The error between the present value and the target value of the total amount of output power from a plurality of power supply devices is reduced. This power supply system (10) comprises a plurality of power supply devices (20) that are connected to a plurality of distributed power supplies (30) and that each output an output power Po,1, Po,2…, Po,N to a power system 100. Each power supply device (20) has a control unit (21) and an output adjustment unit (22). The control unit (21) has a first correction unit (212) and a second correction unit (213). The first correction unit (212) uses as input values a present value P(t) of a total amount Ps of the output power from the power supply devices (20) and a target value P_ref(t) of the total amount Ps, and generates correction information to bring the present value P(t) closer to the target value P_ref(t). The second correction unit (213) determines a command value to bring the present value P(t) closer the target value P_ref(t) based on the correction information. The output adjustment unit (22) sets the size of the output power to a size corresponding to the command value.
