Abstract :This paper deals with the group control method of MMC insert ignore into journalissuearticles values(Modular Multilevel Converter); HVDC system. The proposed scheme increases the number of SMs insert ignore into journalissuearticles values(Submodules); of MMC HVDC system to more than 500 insert ignore into journalissuearticles values(2GW class); without changing the sampling time. This method is called Cluster Stream Buffer insert ignore into journalissuearticles values(CSB); method, and the total SMs are divided into several clusters, and a cluster is composed of 32 SMs. It is easy for the Cluster Stream Buffer method to expand HVDC system to several GW Class and it is easy to keeping the system performances. Consequently, this method was validated using MATAB/Simulink program.
