摘要
为提升工业用户能效,优化企业能效前需评估能效水平,提出了一种基于改进TOPSIS灰色关联分析的能效评估方法,用以寻找用能薄弱环节。首先选取关于生产、经济和环境的7个指标构建能效指标体系,其次通过熵权法计算指标权重,并将工业用户进行能效等级分类,可用于电网对高能耗企业执行差异化电价,最后算例选取某市10个典型高能耗企业用户运用改进灰色TOPSIS分析方法进行能效评估,通过分析得到单位产值能耗指标的权重最大,该指标性能越好则综合能效评价结果越高,并最终将该方法与其他评价方法进行比较验证了所提方法的有效性。
In order to improve the energy efficiency of industrial users and evaluate the energy efficiency level before optimizing the energy efficiency of enterprises,an energy efficiency evaluation method based on improved TOPSIS grey correlation analysis is pro-posed to find the weak link of energy use.Firstly,7 indicators of production,economy and environment are selected to build an energy efficiency index system.Secondly,the entropy weight method is used to calculate the index weight and classify the energy efficiency of industrial users,which can be used for the power grid to implement differentiated electricity prices for enterprises with high energy consumption.Finally,the improved grey TOPSIS analysis method is used to select 10 typical enterprise users with high energy consumption in a city for energy efficiency evaluation.The analysis shows that the weight of the energy con-sumption index per unit of output value is the largest,and the better the performance of the index,the higher the comprehensive energy efficiency evaluation result.Finally,the method is compared with other evaluation methods to verify the effectiveness of the method proposed in this paper.
