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 supercapacitor 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.
