摘要：
Multi-terminal direct current based on Modular Multilevel Converter (MMC-MTDC) system is an ideal transmission scheme for wind farm connection. Considering the control performance of DC voltage control of MMC-MTDC system, a stage-style DC voltage droop control is proposed based on the large power fluctuation of wind farm. Different control modes are adapted at different stages of the wind farm operating. The simulation results show that when the power of wind farm drops sharply, the stage-style DC voltage droop control can make the master station DC voltage control so that the DC voltage of MMC-MTDC system will not have a significant deviation, and control mode switching process is smooth, reduces the impact of wind power fluctuations on the DC system.
