动态调整蚁群-BP神经网络模型在短期负荷预测中的应用
Short-term load prediction based on dynamic adjustment ant colony system and back propagation neural network hybrid algorithm
摘要
Abstract
In this paper, a dynamic adjustment ant colony system (DAACS) is proposed to improve shortterm load forecast accuracy, and a short-term load forecast model is developed by using the DAACS-BP hybrid algorithm of DAACS combined with a back propagation (BP) neural network that is trained by the DAACS algorithm. This model can automatically determine the parameters of neural network based on the data sample.A prediction of the Sichuan power grid loads was made by using the model and the history load data, with a comprehensive consideration of various load-impacting factors such as meteorology, weather, price and date types. The results show a faster convergence and a better forecast accuracy of the hybrid method than those of the traditional ant colony system algorithm-BP neural network or the BP neural network, and also a significant improvement on the generalization capacity of BP neural network. Thus, the hybrid algorithm enhances the efficiency of short-term load forecast of a power system.关键词
