The Intelligent Methods Used in Prediction the Wind Speed and Output Power of Wind Farm

The wind speed and wind power of wind farm prediction become more and more important as the increasing installation of wind turbines and the establishment of the large scall wind farms. Because the stochastic and intermittent property of wind speed, the prediction problem is very difficalt to solve. The prediction method using BP neural network, wavelet BP neural network, and supported vector machine was studied in this paper. The simulation results shows that the method used in this paper can give a better prediction, but there is still more other algorithm need to be studied to enhance the prediction precision.
