| Abstract: | This paper proposes a high voltage direct current （HVDC）system based on modular multilevel converter（MMC） for off-shore wind power. Firstly, this paper explains the operation principle and mathematical model of MMC-HVDC. Then, a novel power decouplingcontrol strategy and a novel capacitor voltage-balancing control scheme are proposed respectively. Finally, MATLAB/SIMULINK simulations have verified the performance of proposed control strategy and MMC-HVDC may be a new circuit topology with significant engineeringapplication value. |
