Abstract: For the security and stability analysis of power systems with large-scale wind farms, it is crucial to construct appropriate and accurate wind farm models. Firstly, the existing model structure of wind turbines and the dynamic equivalence for wind farms are sorted out, and the parameter identification methods of wind power generation systems are elaborated. Secondly, the commonly used time-domain simulation analysis techniques for wind power generation systems in power systems are introduced,which mainly summarizes electromagnetic transient simulation, electromechanical transient simulation, medium-and long-term dynamic simulation, electromechanical electromagnetic transient hybrid simulation, and digital analog hybrid simulation techniques. Then, the new progress in modeling and simulation of wind power generation systems is briefly described. Finally, the challenges and bottlenecks faced by the modeling and simulation techniques of wind power generation systems in power systems are analyzed, and combined with the requirements of the new power system, the modeling and simulation techniques are prospected.
