摘要
针对供应链CO_(2)排放量控制基于无损电力网络、忽略电力线路损耗造成CO_(2)排放的问题,提出碳达峰碳中和背景下电力电缆供应链的CO_(2)排放量控制方法。基于电力潮流分析理论引入CO_(2)排放流概念,并计算CO_(2)排放强度,在节点、支路、支路有功损耗和负荷方面分析CO_(2)排放流分布情况,通过潮流溯源法对CO_(2)排放流溯源分析,将发电侧CO_(2)排放转移至用户侧,结合CO_(2)排放阈值,实现电力电缆供应链CO_(2)减排控制。实验结果表明,所提方法的回归相关系数达到了0.9824,均方误差仅为0.093,与文献方法相比,该方法的误差更小、回归相关系数更高。
Aiming at the problem of CO_(2) emission control in supply chain based on lossless power network and ignoring power line loss,a CO_(2) emission control method for power cable supply chain under the background of carbon peaking and carbon neutrality was proposed.Based on the power flow analysis theory,the concept of CO_(2) emission flow is introduced,and CO_(2) emission intensity is calculated.The distribution of CO_(2) emission flow is analyzed in terms of nodes,branches,active power loss and load of branches.The CO_(2) emission from the power generation side is transferred to the user side through the power flow traceability method,and CO_(2) emission threshold is combined to achieve CO_(2) emission reduction control in power cable supply chain.The experimental results show that the regression correlation coefficient of the proposed method is 0.9824,and the mean square error is only 0.093.Compared with the literature method,the proposed method has smaller error and higher regression correlation coefficient.
