Abstract: As the penetration of wind power increases,the impact of wind power grid connection on the power grid more significant.Wind power configure energy storage can effectively improve the random fluctuation and enhance the schedulability. The paper establishes a model with the highest sales income of the wind energy cluster combined energy storage system as the optimization target,and the ant lion algorithm was used to solve the problem. The optimal configuration of the wind power cluster power standby,energy storage power and capacity are obtained. The results of ant lion algorithm,genetic algorithm and particle swarm optimization are compared. The impact of unit cost and life of energy storage battery on optimization results is analyzed. Finally,a wind farm cluster in Northeast China is taken as an example to verify the effectiveness of the proposed algorithm and model.
