Research on Power System Day-Ahead Generation Scheduling Method Considering Combined Operation of Wind Power and Pumped Storage Power Station

In the proposed wind-storage combined operation technology, storage side is foreseen to play a significant role in power system day-ahead generation scheduling. Based on operational characteristics of pumped stations, dispatching method with wind farms and stations studied. The mode that aims at lowest operating cost proposed, taking into consideration coordination relationship between scheduling benefit total peak-shaving economy fluctuation new energy output. First, constraint reservoir capacity, output power, daily pumping station account, model constructed, objective minimizing costs. Then, imperial competition algorithm applied model. Finally, compared standard particle swarm optimization algorithm. simulation results based 4-unit 10-unit systems indicate effective robust for stations.
