The control strategy of modular multilevel converter was studied. In addition,the main circuit of modular multilevel converter with energy storage has been built in MATL AB/Simulink.The voltage sharing control mode,voltage and current double closed-loop control mode and bidirectional DC/DC converter in Boost mode were used to control the modular multilevel converter with energy storage.The control strategy can be applied in the fields of renewable energy integration,high power energy storage,motor control,etc.It is of great significance in maintaining the stability of power system.
