摘要
设计了基于超级电容器储能的独立光伏发电系统。选用Buck-BoostDC-DC电路作为超级电容器充放电电路。分析了系统的能流模型,结合恒流充电和恒压充电二种储能方式各自的优点,给出了在不同工作状态下的充放电控制策略,通过仿真验证了其可行性。
An independent photovoltaic power system based on a supercapacitor was designed.The bidirectional Buck-Boost DC to DC converter was chosen to charge or discharge the supercapacitor.Analysis was made to the power flow model of the proposed system.Combined with the advantages of the two stored energy methods of constant current charge and constant voltage charge,this paper presented the charge and discharge control strategy under different working conditions.The simulation verified the feasibility of the strategy.
