In order to realize wind power integration with the grid friendly，hybrid energy storage system is adopted to mitigate wind power fluctuation． Firstly，according to the random fluctuation characteristics of wind power，the moving average filtering algorithm and adaptive wavelet packet decomposition method are used to obtain the grid － connected power，and the advantages and disadvantages of different methods are analyzed according to the fluctuation requirements of wind power integration with the grid． Secondly，for the power vacancies and surpluses of grid － connected power，the hybrid energy storage system composed of battery and supercapacitor is adopted to carry out the compensation and absorption，and the power instructions of each energy storage equipment are allocated according to the different response frequency of energy storage equipment because of the different performances． Then，combined with the state of charge ( SOC) of energy storage equipment and output limit constraints，a coordinated control strategy of the combined system of wind power and energy storage is proposed to achieve energy complementarity and prolong the service life of energy storage equipment． Finally，based on simulation analysis of historical wind power data，the effectiveness of the proposed method is verified．
