In this paper, the topological structure of DFIG-based wind power is briefly introduced. Then it focuses on the impact of large scale wind power grid connected to the power grid, which including the power quality, voltage, grid frequency, system stability and etc. After that, the corresponding response is presented, such as using static var compensator (SVC), active power filter (APF) to improve the fault ride through capability of the system. Finally, some new results of wind power research are introduced, including the application of the fuzzy C-means clustering algorithm in wind farm, harmonic emission analysis, and the enhanced wind power model for weak power system, which is of great importance for the development of wind power.
