摘　　要：对于独立光伏发电系统,通常需要储能系统来保证供电的稳定性和持续性。为了吸收光伏电池发出的脉动功率,从而抑制直流母线的电压波动,并满足向负载提供短时大功率的需求,提出了采用超级电容器和蓄电池混合储能方案,并进行了充放电仿真分析,验证了超级电容的蓄电池充放电特点,提出了充放电控制策略。Energy storage system is usually essential for stand-alone PV system to ensure power supply stabil- ity and sustainability. For the sake of pulse power absorption from photovoltaic cells so as to inhibit the volt- age fluctuations of DC bus and to meet the needs of supplying short-term high-power to the load, the paper presents a hybrid energy storage scheme combining the supercapaeitor with battery and conducts a simulated analysis on charging and discharging, which proves charging and discharging characteristic of supercapacitor and battery; it also proposes a charging and discharging control strategy.
