Design and Testing of Photovoltaic Energy Storage Automatic Balancing Control System
In order to improve the efficiency of photovoltaic energy storage automatic balancing control,a photovoltaic energy storage automatic balancing control system is designed.In the design process,firstly,the automation control hardware system is designed based on the FS-AC32 6-port wireless AP controller,SNMP remote network management card and S3900-24T4 24 port L2+switch.Secondly,in order to control the electric energy dispatch and smooth output and realize the balance control of photovoltaic energy storage,the automatic balance control unit of photovoltaic energy storage system is designed by using the method of separate control of the front stage and the rear stage of photovoltaic energy storage system.The results show that the maximum time of photovoltaic energy storage equalization control of the designed system is less than 2 s,and the operation efficiency and automatic equalization control efficiency of the system are improved.
