摘　　要：针对风电场的有功功率波动,采用小波包分解的功率平抑算法,得到满足并网要求的低频信号分量和高频的混合储能系统参考功率,并使用低通滤波分频和信号平滑去噪方法获得飞轮储能和电池储能的参考信号,同时考虑放电深度和循环次数对电池储能系统寿命的影响,构建混合储能系统在计划年限内的全生命周期经济性模型,采用多跟踪器优化算法(MTOA)得到最优的混合储能容量配置。最后,结合风电场实际功率数据,仿真分析验证混合储能系统对功率平抑的有效性和经济性。结果表明:混合储能系统既能保证风电场的有功功率波动满足并网要求,又能充分发挥不同储能形式特性,降低系统运行成本。In response to the fluctuation of active power in wind farms,a power smoothing algorithm based on wavelet packet decomposition was adopted to obtain low-frequency signal components that meet grid connection requirements and high-frequency hybrid energy storage system reference power.Low pass filtering,frequency division and signal smoothing denoising methods were used to obtain reference signals for flywheel energy storage and battery energy storage.Simultaneously,considering the impact of discharge depth and cycle count on the lifespan of the battery energy storage system,a hybrid energy storage system's full life cycle economy model was constructed within the planned years.The optimal configuration of the hybrid energy storage capacity was obtained through multi-tracker optimization algorithm(MTOA).Finally,based on actual power data from the wind farm,simulation analysis was conducted to verify the effectiveness and economic of hybrid energy storage system(HESS)in power smoothing.Results show that HESS can not only ensure that the active power fluctuation of the wind farm meets the grid connection requirements,but also fully utilize the characteristics of different energy storage forms to reduce the operating costs of the system.
