Based on the short-term forecast of wind farm output and the spinning reserve capacity of grid, an operation scheduling strategy for wind power and pumped-storage power system is proposed. After establishing the mathematical model, the simulation tests are conducted and the impacts of grid spinning reserve capacity on the performances of wind power and pumped-storage power system are studied. By comparing the simulations of three typical wind speeds, the differences of pumped-storage power operation are analyzed. The simulating results show that the proposed scheduling strategy is effective and feasible.
