Application of grey regression model in power load forecasting

Based on the GM(1, 1) theory, this paper studies the deficiency in power load forecasting. combining the regression model, the paper proprose a new method to forecast the power load. In this paper, the grey model GM(1, 1) is hybridized into the regression model. This results in grey regression model, which is explained detailedly in succession. Based on an example, the basic grey model and grey regression model are used to forecast power load and results of both models are analyzed and compared. The calculation results show that grey regression theory is credible and accurate to forecast power load.
