Photovoltaic Hybrid Energy Storage Control Strategy Considering Bus Voltage Fluctuation
Hybrid energy storage is one of the important technologies to ensure the stable operation of photovoltaic systems.In order to ensure the stable operation of the optical storage system,a control strategy considering the voltage fluctuation of the busbar is proposed.By decomposing the bus voltage fluctuation size into forward and reverse feed-back,the supercapacitor current in the hybrid energy storage system inner ring reference current was adjusted,then the bus voltage fluctuation correlation amount was used as a control signal to adjust the supercapacitor power,and fi-nally,a simulation platform was built in Simulink.The results show that the voltage fluctuation of the busbar of the control strategy proposed in this paper is significantly improved compared with the traditional control strategy,and the output power of the battery is smoother,which prolongs the service life of the battery.
