基于超级电容与蓄电池混合储能的光伏应用
Photovoltaic applications based on hybrid energy storage of supercapacitors and batteries
摘要
Abstract
The instability of power generation in photovoltaic power generation system is difficult to avoid,and its instability will cause a great burden on the energy storage system,of which the impact on the service life of the battery is the most serious.Based on extended Kalman Filter(EKF)to achieve supercapacitor state of charge(SOC)estimation,according to the real-time photovoltaic output power and SOC of the supercapacitor,a new controllable topology is controlled to achieve hybrid energy storage of supercapacitor and battery,so as to alleviate the sudden change of battery charging voltage.In MATLAB/Simulink,the simulation model is constructed,the results show that the error of EKF estimating SOC is within 4%,and the fluctuation of the input voltage of the battery is significantly suppressed under the hybrid energy storage strategy,which can effectively reduce the impact of photovoltaic output instability on battery service life.关键词
