Photovoltaic power generation has the characteristics of volatility and intermittent,unable to provide stable power load,and hybrid super capacitor of energy storage system can provide moderate energy density and high power density,and long service life,can better given photovoltaic power generation,improve the energy storage efficiency and power quality.Build a hybrid supercapacitor(HSC)photovoltaic energy storage system and a lithium-ion battery(LIB)photovoltaic energy storage system to compare the voltage fluctuations and power changes under different weather conditions.In sunny days,the charging power of HSC module is 7.8％higher than that of LIB module,while the voltage fluctuation of both modules is not large.Under multi-cloud conditions,the charge power of HSC module is 10.4％higher than that of LIB module,and the voltage fluctuation degree of HSC module is less than that of LIB module.Under cloudy days,the charging power of HSC module increased by 15.4％than that of LIB module,and the voltage fluctuation ofboth modules was small,but the charging voltage of LIB showed a downward trend.
