Abstract:In view of the influence of several main factors on urban medium and long-term electricity consumption, four types of forecasting models have been established respectively, namely, linear regression method, industrial output value per unit consumption method, major consumer analysis method, and climate analysis method. The modeling process and validity verification are introduced in detail. The results from numerical example show that the four types of prediction methods established here, applicable for different situations, are able to predict the electricity consumption with small prediction errors.
