新型线性回归模型及其在山东电量预测中的应用

A New Linear Regression Model from Electric Load Forecasting of Shandong Province

提出一种新型线性回归预测模型 ,采用基于相对误差意义下的最小二乘法对回归系数进行计算 ,并以山东省居民用电量预测为实例 ,分别用传统的线性回归模型和新型线性回归模型进行预测。预测结果分析表明 ,新型线性回归模型在预测精度方面有了进一步提高。

A new linear regression forecasting model is presented in this paper, which reckons the coefficient of regression using the least squares method based on the relative error. Also, this paper forecasts the residential electric load of Shandong province as an example using traditional linear regression model and new one respectively. The forecasting results show that the new linear regression model can improve the precision of forecasting at a certain degree.
