Abstract: In allusion to that hybrid energy storage system (HESS) possesses the advantages of high power density and high energy density simultaneously in the stand-alone photovoltaic power generation system, this paper proposed a kind of control strategy of power fractional frequency with hybrid energy storage of microgrid to improve the stability of the system operation. A HESS for stand-alone photovoltaic power generation system was built by simulink. Via power fractional frequency, the system realized the optimal allocation of power output of supercapacitor and lithium ion battery, suppressing the power fluctuation caused by load change and maintaining the stable DC bus voltage. The simulation results show that this method improves the system stability and realizes the reliable power supply for direct current load.
Key words: stand-alone photovoltaic power generation; hybrid energy storage; lithium-ion battery; ultracapacitor
