摘要
分析了灰色模型在电力负荷预测中的适用条件，比较了一般GM（1，1）模型、新息模型和等维灰数递补模型等三种模型的精度及优缺点，利用丰富原始数据预测到各个数列所形成的区间，再利用电力发展与国民经济增长的关系，经过关联分析得到较为合理的预测结果，并用计算机软件提供具体预测方法。
In this paper,the applicable conditions of grey model are studied. The paper compared the precission,advantages and disadvantges of GM (1. 1) model,newInformation model and progressive model of equal dimension grey number. The intervals formed in the sequences are forecasted by primary data,with the relationbetween power development and increasing of national economy, the reasonableforecast results are abtained by insident analysis, and the forecast methods are given from computer software.
