基于用经济学的低碳建筑园区综合能源系统分析与评价

Analysis and Evaluation of Integrated Energy System for Exergy Economics-based Low‑carbon Building Park

在双碳目标下,综合能源系统将越来越多地出现在低碳建筑园区,随着新能源的接入,建筑能源系统越来越复杂,其分析及评价越来越困难。基于经济学理论,首先建立低碳建筑园区能源系统经济学分析模型,并提出考虑效率和损作为能源系统能耗特性评价指标,损成本和经济系数作为能源系统经济特性评价指标的分析及评价方法,最后以某建筑园区能源系统为算例,验证所提能源分析模型的正确性,分析及评价方法的有效性和优越性。

Under the“dual-carbon”targets for achieving the goal of peak emissions and carbon neutrality,a growing number of integrated energy systems are expected to be deployed in the low-carbon building parks.With the accessibility of the new energy,building energy systems become more and more complex,and thus the analysis and evaluation are getting increasingly difficult.Based on the theory of exergy economics,this paper first establishes the exergy economic analysis model for the energy system in low-carbon building park,then proposes the analysis and evaluation method which takes into account the exergy efficiency and loss as the evaluation index for the energy consumption characteristics of the energy system,and exergy loss cost and exergy economic coefficient as the evaluation index for the economic characteristics of energy system,and finally,takes the energy system of one building park as an example,to verify the correctness of the proposed energy analysis model and the effectiveness and advantages of the analysis and evaluation method.
