Title:
POWER SYSTEM MANAGEMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/004048
Kind Code:
A1
Abstract:
Second computing machine systems each controlling each partial area within a whole area each share the actual power generation within the controlling partial area and a transmission line operation limit value with a first computing machine system controlling the whole area and each calculate a suppression amount of a renewable energy within the partial area on the basis of the actual power generation within the partial area and the transmission line operation limit value. The first computing machine system corrects the suppression amounts of renewable energies connected in a non firm fashion within the whole area on the basis of the suppression amounts of renewable energies each notified from each of the second computing machine systems. A third computing machine system controls the power generation amounts of renewable energy devices to suppress the power generation amounts of renewable energies as much as the suppression amounts calculated and corrected by the first computing machine system.
