基于灰色与计量经济模型的用电最优组合预测

Research on Optimal Combined Prediction of Power Consumption Based on Econometric and Gray Model

通过对电力市场需求影响因素的分析，提出了计量经济与灰色预测的优化组合预测模型，经过论证并用实例比较得出此模型比其中任一单一模型预测误差率都小，预测结果更精确，为电力市场用电量需求提供了一个实用有效的预测方法。

According to the analyzing of influencing factors in the demand of electric power market, the optimal combined prediction model based on the econometric and gray model is proposed. It is proved to be more accurate then anyone of the two models. This model provides an effective method of forecasting power demands.
