Introduction was made to the application and characteristics of the three mainstream wind models at the present stage. This paper analyzed the inlfuences of safe and stable operation caused by large-scale wind farms power grid, including changing the power grid tidal current distribution, having impacts on the power grid dispatching and the quality of distribution network. In view of the pres-ent status of wind power industry, this paper proposed wind power prediction, power electronics device and control technology in wind farm, low voltage ride through etc research hotspot issues and prospected the trend of wind power development.
