Accurate model of wind turbines active power is the key to forecasting active power. Firstly, based on the characteristics of the mechanism of different wind turbines, this paper put forward the analysis of wind turbines in the physical mechanism of each tip, it summarizes the aerodynamics and the control strategy of generating;The wind speed - active power model is proposed based on the measured data, and then the measured data model is set up from the mathematical statistical algorithms, intelligent algorithm, as well as the uncertainty modeling. Finally, the paper analyzes the two kinds of modeling method in the practical engineering application, prospects the future demand and the trend of research.
