For inland wind power, there are many problems with AC interconnection, and the double terminal voltage source converter based high voltage direct current(VSC-HVDC)system can not satisfy the requirements. Multi-terminal VSC-HVDC(VSC-MTDC)is the tendency of wind power integration. The coordination of adaptive DC voltage droop control and HVDC additional frequency control was proposed. The droop coefficient varies adaptively according to the value and direction of DC voltage change and the power margin of the converter station, optimizing power distribution between converter stations. And the additional frequency control is introduced into VSC-MTDC. Takeing full advantage of frequency adjustment capacity. Controller parameters are easy to set and simple. The simulation results show the effectively of coordinated control strategy.
