摘　　要：超级电容器与蓄电池混合使用可以充分发挥蓄电池能量密度大和超级电容器功率密度大、充放电速度快的优点,大大提升储能系统的性能。针对独立光伏系统的特点,设计了一种有源式混合储能方案,建立了系统的模型和控制环节。实验结果表明,在负载功率脉动时,蓄电池能够工作在优化的放电状态,并能够有效地减少放电小循环次数,对解决光伏等可再生能源系统中的储能问题,具有现实可行性。Super capacitor and battery hybrid used can give full play to some advantages such as the high energy density of batteries,the high power density of supercapacitors and the advantages of fast charge and discharge,then the storage system performance has been improved greatly.In this article,a program of active hybrid energy storage has been designed,based on the characteristics of independent PV systems,to build the system model and control link.The results show that the battery could work in optimizing discharge condition,and can effectively reduce the number of discharges small cycles when the load power is pulsating.It is realistic practicable to solve the problem of energy storage for PV and other renewable energy sources systems.
