摘要:在新型电力系统建设背景下,电网行业积极推行碳减排技术应用,科学评估碳减排技术的综合效益对技术的合理选用具有重要的参考价值。本文构建了基于全生命周期评价(Life Cycle Assessment,LCA)的电网工程碳减排技术效益评价方法:在分析电网工程碳减排内涵的基础上,提出电网工程碳减排技术碳减排量核算模型;基于成本效益分析法、增量收益分析法构建增量效益模型,同时提出以碳减排单位投入净现值收益(PNPV)指标作为关键判断指标。希望为电网工程碳减排技术评价提供方法依据。关键词:碳减排技术;效益评价;全生命周期评价Abstract:In the context of the construction of a new-type power system,the power grid industry is vigorously promoting the application of carbon emission reduction technologies. A scientific evaluation of the comprehensive benefits of these technologies is of great significance for their rational selection. This study develops a benefit evaluation approach for carbon emission reduction technologies in power grid projects using Life Cycle Assessment(LCA). After clarifying the connotation of carbon emission reduction in power grid projects,a calculation model for the carbon emission reduction amount of relevant technologies in such projects is established. An incremental benefit model is formulated by integrating the cost-benefit analysis method and the incremental revenue analysis method. Additionally,the Net Present Value of Carbon Emission Reduction per Unit Investment(PNPV)is proposed as a crucial evaluation indicator. Hopes to offer methodological foundation for the assessment of carbon emission reduction technologies in power grid projects.Keywords:carbon emission reduction technology;benefits evaluation;life cycle assessment参考文献[1] 刘提,吴震,陈聪,等.基于碳排放因子法的典型500kV变电站建设过程碳排放核算[J].全球能源互联网,2025(2):216-223.[2] 刘继文,侯强,晏鹏宇.基于主从博弈的具有多类型产消者的微电网电力交易动态定价策略[J].工业工程,2024(5):138-149.[3] 张喜泽.上海公里级高温超导电缆输电工程碳排放分析[J].低温与超导,2022(12):21-24.[4] 胡亚山,庄典,朱可,等.混凝土结构与钢结构变电站建筑全生命周期碳排放对比研究[J].建筑科学,2022(12):275-282.[5] 张敏,邹盛,王庭华,等.户内变电站小型化优化设计及物化阶段碳排放评价方法[J].南京工业大学学报(自然科学版),2023(4):425-433.[6] 俞春华,陈国华,喻鸿,等.不确定需求下考虑协议库存的电网物资供应优化建模[J].工业工程,2024(6):82-92.[7] 关艳,高曦莹,陆心怡,等.考虑碳排放的新能源电网电力交易动态定价方法[J].可再生能源,2024(1):112-118.[8] 苏雅亨,李雨佳,赵启新,等.碳排放权交易市场对区域电网投资成本的影响研究——来自中国准自然试验的证据[J].投资研究,2024(10):144-159.[9] 薛邵琴.基于减碳技术的建筑全生命周期环境-经济性评价[D].北京:北京交通大学,2025.建筑经济,2026(1):92-98
