摘要
本文应用灰色预测法对江苏省用电量进行预测。通过对2004———2009年江苏省用电量原始数据进行生成处理来寻找系统的规律,生成有较强规律性的数据序列,然后建立相应的微分方程模型,从而预测用电量的未来发展趋势,并通过残差修正模型使得模型的精确程度有所提高。
This paper aims to forecast electricity consumption in Jiangsu Province by the gray prediction method.By using the original data from 2004 to 2009 to find the law of the system to generate a strong regular data sequence,and then create the appropriate differential equation model to predict the future trend of electricity consumption.In addition,the paper also use residual modified model to improve the accuracy of prediction.
