随着风力发电的发展，风电波动带给电网的影响越来越明显，平滑风电出力显得很重要。针对风电功率波动特性，提出基于小波包分解法，得到风电并网功率、混合储能系统参考功率和充放电状态。结合蓄电池和超级电容的荷电状态，提出了能量管理协调控制策略，实现了储能系统内部功率修正，算例结果表明：能量管理协调控制策略能完成混合储能系统内部功率最佳修正，且可以有效的平滑风电出力。最后以实际风电数据为依据，在MATLAB中建立了数学仿真模型，证明了该控制策略的有效性。

With the development of wind power generation, the impact of wind power fluctuations on the grid is becoming more and more obvious, and smoothing wind power output is very important. Aiming at the fluctuation characteristics of wind power, a wavelet packet decomposition method is proposed to obtain the wind power connected to grid, the reference power of the hybrid energy storage system, and the state of charge and discharge. Based on the state of charge of the battery and super-capacitor, the coordination control strategy realizes the internal power correction of the energy storage system. The results of the calculation examples show that the coordination control strategy can complete the optimization correction of the internal power of the hybrid energy storage system and effectively smooth the wind power output. Based on actual wind power data, by establishing a mathematical simulation model in MATLAB, the effectiveness of the coordination control strategy is proved.
