Study on A PV System with Supercapacitor and Battery Hybrid Energy Storage

超级电容器功率密度大,循环寿命长,适合与能量密度大的蓄电池混合使用,共同组成独立光伏发电系统中的储能部分。针对独立光伏发电系统的特点,分析了两者的特性,提出了1种超级电容与蓄电池混合储能的充电控制方案。实验结果表明,超级电容和蓄电池混合储能可有效实现系统的能量管理,确保光伏板和混合储能系统的协调工作。

Supercapacitor and battery combination in independent photovoltaic power generation system, are conducive to play battery＇s big energy density and supercapacitor＇s big power density, long cycle life. In the light of the characteristics of independent photovoltaic power generation system. This paper proposes a supercapacitor and battery charging control scheme of the hybrid energy storage. The experimental results show that the supercapacitor and battery of the hybrid energy storage system can realize energy management,ensuring photovoltaic panels and hy- brid energy storage system work in concert.
