Abstract
For the modeling, simulation and operation control of high capacity modular multilevel converter based multi-terminal DC grids ( MMC-MTDC Grids) , in this paper the Thévenin equivalent modeling method of half-bridge sub-module based MMC is ana-lyzed, and the parallel simulation method of multi-terminal DC grid based on PSCAD/EMTDC is introduced.In order to improve the control stability and reliability of multi-terminal DC grid, DC voltage droop control strategy for the multi-terminal DC grid operation control is proposed.Finally, a four-terminal MMC-MTDC grid parallel model is built in PSCAD/EMTDC and the validity of the pro-posed DC voltage droop control strategy of multi-terminal DC grid is verified.关键词
