A control strategy has been proposed based on five terminals voltage source converter (VSC)–HVDC typical topological structure of large grid‐connected offshore wind power system, which means that VSCs on the wind farm side are controlled with AC voltage control method and VSCs on the grid side are controlled with DC voltage droop control method. A simulation model has been built on power systems computer aided design (PSCAD)/electromagnetic transients including DC (EMTDC) platform, and with it, several simulations have been conducted such as start‐stop of wind farm, power fluctuation and suspension of converter station. In the end, the control strategy is proved out to have coordination control capability and flexibility.
