A Combination Model for Short Term Wind Power Forecasting

For analyzing the accuracy of wind power prediction, an analyzing model combined with multi-leaner and dynamic weight distribution is proposed. With this method, Numerical Weather Prediction (NWP), Wind power data (historical) and weather data (historical) are structured into several sample sets, each set has a different weight value, which determined by the training errors, these sample set is trained by different learner algorithm with a weight too. Finally, using these models to predict the outputs. The experiments indicate the effectiveness of the method this paper proposed. Compared with Single model of Support Vector Machine and Artificial Neural Network, the combination method has better performance in both calculation accuracy and generalization.
