摘　　要：在深入分析MIES煤炭生产运输与能量流动的“煤-能”耦合机理的基础上,综合考虑MIES清洁能源及衍生能源的多样性,针对传统能效评估方法忽略系统内部子过程及评价结果单一性的缺陷,提出一种基于松弛变量网络数据包络分析(NSBM-DEA)的MIES能效评估方法。该方法能够综合计及MIES特有的煤-能耦合、品位多相及多能利用特性,并通过对MIES关联子过程能效影响进行量化分解,从而实现对MIES总体能效及薄弱环节的科学评估。最后,以山西省某矿山实际能源系统为例,进行多场景计算分析,仿真结果验证了所提方法的有效性。Based on an in-depth analysis of the"coal-energy"coupling mechanism between coal production,transportation,and energy flow in MIES,this paper comprehensively considers the diversity of clean energy and derived energy in MIES.Addressing the limitations of traditional energy efficiency assessment methods,which often neglect internal sub-processes and provide unidimensional evaluation results,we propose a new energy efficiency assessment method for MIES based on Network Slacks-Based Measure Data Envelopment Analysis(NSBM-DEA).This method comprehensively accounts for the unique characteristics of MIES,including coal-energy coupling,multi-phase quality,and multi-energy utilization.By quantitatively decomposing the energy efficiency impacts of interrelated subprocesses in MIES,the proposed method enables scientific assessment of overall energy efficiency and identifies weak links.Finally,we conduct multi-scenario computational analyses using an actual energy system from a mine in Shanxi Province as a case study.The simulation results demonstrate the effectiveness of the proposed method.
