基于分段灰色模型的负荷预测方法

Method of Load Forecasting Based on Segmentation Grey Model

基于灰色GM(1,1)模型在负荷预测运用中的局限性,引入分段灰色较正GM(1,1)模型;同时采用数理统计的-检验法对模型精度进行检验。通过实例应用表明,分段灰色校正模型具有较高的拟合精度和预测精度。

Because of the limitation of grey model GM （1,1） in applying of load forecasting, we use grey emendation GM （1,1） model. And we also use symbolic statistic’ s T-Test to verify the precision of the model. Through the example, it indicate that segmentation grey model has higher fitting precision and forecast precision.
