Model and Methodology for Dynamic Carbon Emission Metering on Power Grid Side
摘要
Abstract
The current situation of ambiguous boundaries in carbon emission accounting,slow updating of carbon emission factors,and the absence of spatio-temporal dynamics in power grids,necessitates the construction of a carbon emission meter-ing model on transmission side,substation side,and distribu-tion side as measuring nodes.The principle of QIO model states that the total amount of carbon emissions entering a node equals to the sum of the internal losses emissions of the node and the emissions flowing out of the node,Utilizing the elec-tric energy metering network as a foundation,carbon emissions were measured for each link on the grid side using electric en-ergy measurement data.The calculation results of carbon emis-sions and the associated factors exhibit the characteristics of spatial flexibility and temporal dynamics.Finally,the effective-ness of the method was validated through a numerical case study.The metering model has a positive significance for ac-curate carbon accounting for power grids,enabling a compre-hensive grasping of the direction of carbon emissions,and providing a guidance to users in actively implementing carbon emission reduction.关键词
