Abstract :
This paper proposed a novel Current Control based modular multilevel Voltage-Source Converter (CCVSC) topology suitable for different rates of voltage application, especially for the interface of renewable power sources with the main gird and power transmission and distribution usage. The fundamental concept and the applied control scheme are introduced. The unbalanced energy mitigation function of the proposed converter has been explained, and the concerned parameters have been deduced. The characteristics and advantages compared with the existing VSC HVDC are discussed. The simulation results of a 20 MW dual-end CCVSC HVDC system illustrate the feasibility of this new topology and efficiency of the control scheme.
