电网侧动态碳排放计量模型及方法OA北大核心

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.
