摘要：

A short-term forecasting model of neural network for wind power generation with the combined loss function was proposed, in order to reduce the side effect of large-scale wind power integration on power system energy balance and increase system's wind power accommodation ability. A classification method was introduced into the model, and a BP neural network short-term wind power prediction model with the goal of minimizing the combined loss function was proposed, in order to improve the utilization of raw data information. The combined loss function was constructed by the mean square error loss function, the cross-entropy loss function and the rank loss function according to different weight ratios. Compare to the prediction method based on separate loss functions, the combined loss function proposed can effectively improve the prediction accuracy from real wind farm data test.
