Document Type and Number:
WIPO Patent Application WO/2021/125287
Kind Code:
A1
Abstract:
Provided are a power control system, a power control device, a computer program for power control, and a power control method which can stably control a power system including a natural energy power generation device. This power control system 1 comprises: a natural energy power generation device 3 which generates electric power by using natural energy; and a power control device 2 provided with a maximum power detection means for detecting maximum power output from the natural energy power generation device 3, a system information detection means for detecting system information pertaining to a power system 9, and an output power command means for calculating and instructing output power to be output from the natural energy power generation device 3 on the basis of the detected maximum power and the detected system information, wherein, when the frequency of the power from the power system 9 is determined to be lower than a predetermined first frequency range on the basis of the system information detected by the system information detection means, the output power command means instructs the natural energy power generation device 3 to suppress natural energy output power for reducing the output power.
