Abstract:

Abstract:The load prediction is the base and important premise for power system planning and operation. The principle of the comprehensive model method was introduced. A new comprehensive prediction model was established, and using the variance reciprocal method, the weighting coefficients of each single model were determined. The analysis of calculation examples shows that the prediction precision of the comprehensive model method is higher than the prediction precisions of each single model method.
