Abstract—Pumped storage is an effective option for solving the problems related to large scale wind power integration systems, such as peak regulation, etc. The coordinated generation dispatch for power systems with the mix generation of wind power, pumped storage and thermal power has dominant economical and environmental benefits. This paper proposed a two-stage coordinated generation dispatch model for this kind of system, which is consisted of day-ahead dispatch and hour-ahead dispatch. The model has the merits in accommodating uncertain wind power, reducing the operating reserve demand, at the same time, the proposed coordinated dispatch mode optimizes the pumped storage’s operation from two aspects of the system economy and reliability. The modified IEEE-10 generator system is used to verify the effectiveness of the proposed model. The research has the guideline significances in determining the dispatch schemes for the systems with wind power and pumped storage, as well in planning pumped storage capacity.
