以超级电容和蓄电池为例,分析了功率型和能量型混合储能不同拓扑结构的优缺点,总结出混合储能拓扑结构选取的一般原则。基于二级低通滤波,提出根据频谱图确定滤波时间常数的混合储能控制方法,并考虑电池充放电功率限制,对滤波输出功率进行修正。用Matlab对算法平滑实际光伏出力进行了仿真验证,结果证明该算法能够满足光伏并网联络线功率要求,并使电池充放电功率不越限。

Taking the super capacitor and battery for example, this paper analyzes advantages and disadvantages of different topology of the power and energy hybrid energy storage, and sums up the general rules of the selection of hybrid energy storage topology. Based on secondary low pass filter, it proposes filter time constant control method of the hybrid energy storage according to the spectrum diagram, and modifies the filtering output power considering the battery charge and discharge power limitation. The algorithm is simulated and verified using Matlab to smooth the actual photovoltaic power. The results show that this algorithm can meet the requirements of the photovoltaic (PV) grid tie line power and make the battery charge and discharge power not out-of-limit.
