Combination Regression and Neural Network for Short Term Load Forecasting

The forecasting of gas demand has become one of the major research fields in gas engineering. Gas demand possesses dual property of increasement and seasonal fluctuation simultaneously, so it makes gas demand variation possess complex nonlinear combined character. Accurately forecast were essential part of an efficient gas system planning and operation. In this paper, a new forecasting model which named regression combined neural network is put forward. In this approach we used regression to model the trend and used neural network for calculating predicted values and errors. Taking the advantages of regression analysis and artificial neural network, the model improves the forecasting accuracy of power demand obviously. The results indicate that the model is effective and feasible for load forecasting.
