Wind power generation develops rapidly encountered in global environmental and energy crisis, and the proportion of wind power generation is becoming higher and higher in primary energy generation. Large-scale wind power integration poses severe threat to power system frequency stability. Firstly, the requirements for active power and control and frequency regulation when wind turbines integrated in power system in several developed countries are introduced. Secondly, the influence of large-scale wind power integration on power system frequency stability is analyzed. Survey and summary are carried out in three aspects, including inertial support, primary frequency regulation and comprehensively supporting inertial support, and primary frequency regulation provided by wind turbines for power system. Finally, the methods of improving frequency stability of power system with high wind power permeability are reviewed and analyzed, by applying large-scale energy storage technique and demand side management technology.
