摘　　要：在“双碳”目标下,特高压交流工程凭借其先进的技术手段,在消纳清洁能源、降低传输损失方面将发挥更大作用,但对特高压交流工程减碳效益的研究较少。以负荷落点区域为研究对象,提出了特高压交流工程运行减碳效益的量化方法。首先,对送受两端电力潮流分布进行模拟计算,确定输电通道潮流比例;其次,对电源区域进行电量平衡分析,确定工程输送清洁能源电量,结合碳排放因子测算负荷区域碳减排量,利用Shapley值根据贡献度计算工程的减碳效益;最后,以实际工程为例进行算例分析。结果表明,特高压交流工程能够通过提升清洁能源消纳能力减少碳排放。Under the"dual carbon"goal,the ultra-high voltage(UHV)AC project,with its advanced technological means,will play a greater role in consuming clean energy and reducing transmission losses.Considering that there is relatively little research on the carbon reduction benefits of UHV AC projects.this paper proposes a quantitative method for evaluating the carbon reduction benefits of UHV AC projects,taking the load landing area as the research object.Firstly,the distribution of power flow at both ends of the transmission and reception is simulated to determine the power flow proportion of the transmission channel.Secondly,an analysis is conducted on the electricity balance of the power supply area to determine the amount of clean energy transmitted by the UHV AC project.The carbon reduction emissions in the load area is calculated based on carbon emission factors,and the Shapley value is used to calculate the carbon reduction benefits of the UHV AC project based on its contribution.Finally,an actual project is taken as an example for numerical analysis.The results indicate that the UHV AC project can reduce carbon emissions by improving the ability to accommodate clean energy.
