With large scale wind power integrated into power system,in order to ensure the safe operation of power grid,it is necessary to predict the wind power generation.This paper introduces the prediction methods of wind power generation generally according to different classification criterion,then analyzes the wind power generation technologies based on historical and numerical weather respectively,and summarizes the main mod-els of wind power generation and its advantages and disadvantages,analyzes the predition evaluation index. Draws the conclusion that choosing the reasonable prediction model and optimizes its performance is the key to the wind power generation .After reviewing the status of the predition technologies at home and abroad,some existing problems in the current is pointed out,finally some advice about wind power generation research and development is proposed.
