影响电力需求预测各因素的客观权重分配方法

确定影响电力需求预测各因素的权重分配是进行电力发展规划需求预测后评价的一项重要内容。针对电力行业五年期需求预测后评价中待评价年个数较少而影响因素较多的特点，文章在一般多因素客观权重分配方法的基础上，提出了加权互信息量的概念，同时引入相对强度熵，得到了一种影响电力需求预测各因素的客观权重分配方法，并通过计算实例证明了该方法的有效性和实用性。

An Approach to Allocate Impersonal Weights of Factors Influencing Electric Power Demand Forecasting

It is one of important contents in post-evaluation of electric power demand forecasting for electric power development plan to decide the weights allocation of factors influencing electric power demand forecasting.According to the feature that in the post-evaluation of five-year electric power demand forecasting there are few years to be evaluate while the number of influencing factors is more,on the basis of conventional multi-factor impersonal weights allocation method the authors propose a concept of weighted mutual information and lead in the entropy of relative intensity,thus an approach to allocate impersonal weights of factors influencing electric power demand forecasting is obtained.Case study results show that the proposed approach is effective and practicable.
