| Abstract: | Growing penetration of wind power challenges to power system security, since the conventional generators maynot have sufficient capacity to compensate wind power fluctuation plus the reverse peak regulation. In this paper,the high-capacity pumped-storage and fast-response battery-storage are coordinated to compensate the variationof both wind power and load, aiming at shifting peak load, responding to wind power ramping, reducing thecurtailment of wind and stabilizing the output of thermal units. A practical framework is designed for optimizingthe operation of the hybrid system consisting of the wind, pumped-storage, and battery storage, which can takefull advantages of pumped-storage and battery-storage. The detailed mathematical formulations of the pumpedstorageand battery-storage are built. Three cases are studied to demonstrate the advantages of the proposedcoordination method. |
