Abstract
In view of the output fluctuation and model of instability in the extreme learning machine algorithm, this paper raises the method of switching model limit learning algorithm for ultra short term power load forecasting.The al-gorithm divides a plurality of the established neural network model into two parts: keeping model of small errors and updating model of large errors by switching model guidelines.To keep model has no need for online update, so as to reduce the volatility of the output of model; updating model needs to adopt stochastic methods to update online, so that the training error reaches a minimum, and the generalization ability of the model is improved.Finally, through the simulation of power load forecasting of a certain area, the predicted results show that the proposed method can im-prove the prediction speed, save computing time, and has better generalization ability and prediction accuracy.关键词
