面向新型电力系统的模块化多电平换流器控制策略研究
Research on Modular Multilevel Converter Control Strategy for New Power Systems
摘要
Abstract
Aiming at the problem that renewable energy integration will cause power grid instability,the modular multilevel converter with energy storage function can implement the basic function of modular multilevel converter,and also can transfer energy to AC and DC grid in both directions,which improves the fluctuation and power quality of the renewable energy power system.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.关键词
