Abstract A wind speed forecasting model for wind farm based on support vector machine is proposed. Through wavelet decomposition and genetic algorithm, the data are preprocessed and the parameters are optimized. The model includes data processing unit, parameter optimization and support vector machine unit. The historical wind speed data is input to the model, and the model outputs the future wind speed data. Meanwhile, the adjustable parameters of the model is introduced, in order to improve the general adaptability for the different wind speed data. The simulation results show that the forecast wind speed is following the true value, what’s more, the model can adapt to different wind data.
