摘    要:在分析模糊多项式拟合法建模机理的基础上,建立了改进模糊多项式拟合模型,通过适当减小拟合曲线在后段的拟合误差来提高预测精度。文中的改进方法为处理预测中的定性模糊因素提供了一种灵活的手段。实例验证了该改进模糊的可行性与优越性。

关 键 词:模糊多项式拟合法  负荷预测  电力系统  建模

Abstract:On the basis of analyzing the modelingmechanism by fuzzy polynomial fitting an improvedpolynomial fitting model, in which the forecasting precision is increased by properly reducing the fitting error of the fitting curve at its rear part, is accomplished. The improvement method presented in this paper provides a flexible means to deal with the qualitative fuzzy factors in load forecasting. The feasibility and advantage of the presented model is tested and validated by actual examples.
Keywords:load forecasting  fuzzy mathematics  polynomial fitting
