摘　　要：针对脉动荷载波动性大、易对储能电池充放电造成冲击等问题,研究一种由储能电池及超级电容组成的混合储能系统,建立一种自适应能量控制策略并将其应用于直流微网中。该控制策略采用移动平均滤波算法,使储能电池的充放电状态得到优化,增加了其充放电次数。对该系统的组成结构和工作原理做了介绍,对所提控制策略做了详细研究,最后将该控制策略应用于实验样机,证明了其有效性。In view of problems such as the high fluctuation and the impact on energy storage battery charging and discharging of fluctuating load, a hybrid energy storage system composed of energy storage battery and super capaci- tor is studied, and then an adaptive energy control strategy is proposed and applied to the DC microgrid. The strate- gy uses the moving average filter algorithm to optimize the charging and discharging state of the energy storage bat- tery, which increases the charge and discharge time. The composition structure and working principle of the system are introduced in this paper, and then the proposed control strategy is studied in detail. At last, the control strategy is applied to an experimental prototype, which proves its effectiveness.
