Electric load prediction method used for electric power based on factors of temperature and festivals and holidays

The invention relates to a data processing method for monitoring and prediction in the electrical power system, in particular to an electric load prediction method used for electric power based on factors of temperature and festivals and holidays. The electric load prediction method used for the electric power based on the factors of the temperature and the festivals and holidays comprises the steps of building a model by using historical data, distinguishing electricity utilization data in the festivals and holidays from electricity utilization data in workdays, building a judging dummy variable, building a short-term prediction model of the load by using the temperature and the dummy variable, carrying out a significance testing of independent variables of the model under the alike information criterion (AIC), and finally obtaining a short-term load prediction value by using the model. Due to the fact that the load prediction value is obtained according to the model and by considering the factors of the tem
