Summary:In this paper, an in-depth study on the interaction characteristics and coordinated control technologies of wind power and DC systems is carried out. This paper first defines the physical significance of the interaction between wind power and DC in the receiving grid. At the same time, an interaction factor that takes into account the strength of the wind and DC relative AC system and the relative impedance between them is established. Then the factors affecting the interaction between wind power and DC system are analyzed. Finally, the coordinated control strategy between the them is discussed. The North China Power Grid, which is connected by offshore wind power and Xitai DC, is used as an example. The results show that the smaller the electrical distance between wind power and DC system, the larger the scale of the two systems and the more obvious interaction between them.
