园区级区域综合能源系统综合评价方法及应用

Comprehensive Evaluation Method and Application Study of Campus-level Regional Integrated Energy System

随着“碳达峰、碳中和”和新型电力系统建设目标的提出,进一步发展区域综合能源系统是实现这些目标的重要途径。结合代表性园区综合能源系统项目案例,采用主客观结合的层次分析—熵权法来确定指标组合权重,优化单一层次分析法确定权重主观性过强的缺点。通过数据归一化处理,将定量指标和定性指标进行融合,建立模糊判断矩阵,通过模糊综合评价法进行综合评价。结合综合能源系统评价等级,给出该系统的总体表现得分。研究发现:选取的典型区域综合能源系统的综合水平较优,在技术效益和环境效益两个维度上的水平处于优,但在能源效益、经济效益和社会效益三个维度上的水平处于良。并且通过对19个二级指标评分结果和影响因素进行分析,提出了能源系统优化的方向和建议,为当前的区域综合能源系统运营提升,以及未来区域综合能源系统规划设计提供有益的帮助。

With the proposed goals of“carbon peaking and carbon neutral”and new power system construction,further development of regional integrated energy system is an important way to achieve these goals.Combined with the case of a representative park integrated energy system project,a combination of subjective and objective hierarchical analysis-entropy weighting method is used to determine the weight of the index combination,optimizing the shortcomings of a single hierarchical analysis method to determine the weight of too subjective.By normalizing the data,the quantitative and qualitative indicators are fused,a fuzzy judgment matrix is established,and comprehensive evaluation is carried out by the fuzzy comprehensive evaluation method.The overall performance score of the system is given in combination with the evaluation level of the integrated energy system.
