Abstract：There are a variety of methods to predict long-term electric load. However,the limitations of the methods are a number of factors. The linear regression model,quadratic polynomial model and gray prediction model are proposed in the paper for power load forecasting,respectively. These thee methods are taken together again to establish the variance-covariance combination forecasting model. By comparison concluded,this method greatly reduces errors,improves the prediction accuracy and can scientifically predict long-term power load.
