Analysis of Accumulated Temperature Effect and Application in Forecasting

In short term load forecasting,weather factors in some conditions can cause the accumulated temperature effect of changes in load.By analyzing the expression of accumulated temperature effect,it is explorated the relation between accumulated temperature effect and weather factors.Effective accumulated temperature is introduced.It is used to simulate accumulated temperature effect in the forecasting model.In the presence of study,a forecasting model based artificial neural network is proposed.This model can em- body accumulated temperature effect during forecasting by using adequate meteorologic factors.By using the given forecasting model the obtained forecasting results are more accurate.
