摘要
利用超级电容充电条件不受限制、循环寿命长和蓄电池比能量高的优点,结合太阳电池最大功率点跟踪控制回路,对超级电容和蓄电池的混合储能在独立式光伏系统中的应用进行了实验研究。结果表明,太阳电池在外界环境波动较大的情况下,蓄电池仍能稳定充电,提高了系统的利用率,减小了蓄电池的循环次数,提高了蓄电池的使用寿命。
Based on the advantages of unlimited charge conditions and long cycle life of ultracapacitor,and high energy density of batteries,with the maximum power point tracking control loop of solar cells,the ultracapacitor and battery hybrid energy storage in stand-alone PV systems was researched.The results show that although solar fluctuations in the external environment,battery charger can still stabilize and improve system utilization,reduce the number of cycles the battery and improve battery life.
