Aiming at the disadvantages of prediction model of single BP neural network, a prediction model was presented by combining AdaBoost algorithm and BP neural network for improving the forecasting accuracy of single BP neural network. The ensemble BP network based on AdaBoost is used as intelligent algorithm. Overcoming the instability of single BP neural network, the proposed models can give more accurate and stable prediction for the novel conditions. The main influence factors for prediction of market demand of refrigerator are analyzing detailed and used as the inputs of proposed prediction model. The efficiency of the proposed prediction model was tested by simulation of the market demand statistical data of a refrigerator enterprise in China. The simulation results have shown that the higher accuracy is expressed in this proposed model, and it is applicable to practice.

Wind power prediction is important to the operation of power system with comparatively large mount of wind power. It can relieve or avoid the disadvantageous impact of wind farm on power systems. Because the traditional neural network may fall into local convergence, so it will be effective to improve the training algorithm to improve its convergence and accuracy of prediction. In this paper, a model for wind speed prediction was constructed based on adaptive learning rate of BP neural network, the selected historical wind speed data of a certain time were use as model inputs, so that we can predict the wind speed of the same time in the future and its accuracy analysis. Research shows that the improved BP neural network model can effectively achieve the long-term wind speed prediction.
