两种改进的电力负荷灰色预测模型的应用

以本地区某县级电网的用电负荷的预测为例,对比分析了GM-Malkov模型和改进的等维递补灰色模型两种模型的预测结果和单纯的灰色GM(1,1)模型的预测结果。预测结果表明,灰色-Malkov链改进方法及中等维数的等维递补灰色预测模型的预测精度较之单纯的GM模型都有较大提高。

Application of two Forecasting Model based of Grey Forecasting Model for power load forecasting

for example, forecasting the power load of one county administrative region of Hunan Changde by the grey forecasting model of equidimensional filling vacancies and Grey-malkov Chain Model, comparison and analysis the forecasting result by the two forecasting Model with the forecasting result by the Grey forecasting Model. Thus it is proved that the two proposed model can possesses high forecasting accuracy.
