System operation combining wind power and energy storage can improve working characteristic of wind power grid and its economic and environmental benefits. When energy storage is applied to peak load shifting on wind power, system dispatching depends on time-of-use price making. Then, there is a different status in process of dispatching between time-of-use generation price and system combining wind power and energy storage. Therefore, in this paper master-slave game is established to achieve different decision makings for dynamic game optimization. Time-of-use generation price is chosen as master for improving environmental benefits, on the premise of guaranteeing power selling benefit, taking reducing emission of CO2 and SO2 as optimization goal. Dispatching model combining wind power and energy storage is chosen as slave, taking improving economic benefits as optimization goal. Simulation in 10-motor system reveals that when slave considers only economic benefits, solution of Nash equilibrium generated under guidance of master-slave game plays guiding role of time-of-use generation price as main body to improve environmental benefits and realize win-win situation of economic and environmental benefits. At last, strategy set generated in optimizing process of master-slave game is used to analyze correlation of indexes between environment and economics, expose inner link between indexes and reveal causes of benefit win-win.
