Research on combination forecasting method and application in electric power load forecasting

WANG Jiquan,ZHAO Yulin,MA Li(Engineering College,Northeast Agricultural University,Harbin 150030,China)  
In this paper,through the research on method of solving weight combination forecasting model,a method that used quadratic programming for weight of combination forecasting model was presented.The method not only overcame the shortage of the Lagrange multiplier method which couldn't ensure nonnegative condition of weight,but also simplified the calculating procedure of weight because quadratic programming problem could be solved by MATLAB software.The sampling calculation showed that the precision of combination forecasting model was higher than that of the single model,the error square sum of combination forecasting model was less than that of the single model,thereby,the validity of the method was proved.
