Abstract
GM(1,1)model is a kind of common method for medium and long term load forecasting. In order to solve prob-lems of the residual error GM(1,1)model in judging the symbol of residual error predicted value,this paper presents a kind of improved residual error GM(1,1)model based on na?ve Bayes method.According to historical load growth rate interval, this model can divide load growth states and count numbers of residual error sign under different states as well as numbers of residual error sign a year ago of each state. Then it applies na?ve Bayes method in building the classifier and judging the sym-bol of residual error predicted value. The improved model was applied in electricity consumption forecasting in a county. Ex-ample result indicates that this improved model can effectively improve precision of medium and long term load forecasting which means certain practical value.关键词
