电网侧动态碳排放计量模型及方法
摘要：针对当前电网碳排放核算边界模糊、碳排放因子更新慢、缺乏时空动态性的情况，构建以输电侧、变电侧、配电侧等为核算节点的碳排放计量模型。基于准输入输出模型（Quasi-input-output，QIO）中流入节点的碳排放总量等于节点内部损耗和流出结点碳排放量之和的原则，以电能计量网络为基础，利用电能量测数据对电网侧各环节进行碳排放计量。碳排放量、碳排放因子等计算结果具有空间上的灵活性和时间上的动态性特征。最后，通过算例验证方法的有效性，该核算模型对于电网进行准确碳核算、掌握碳排放流向以及引导用户主动实施碳减排具有积极意义。
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 metering model on transmission side, substation side, and distribution 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 electric energy metering network as a foundation, carbon emissions were measured for each link on the grid side using electric energy measurement data. The calculation results of carbon emissions and the associated factors exhibit the characteristics of spatial flexibility and temporal dynamics. Finally, the effectiveness of the method was validated through a numerical case study. The metering model has a positive significance for accurate carbon accounting for power grids, enabling a comprehensive grasping of the direction of carbon emissions, and providing a guidance to users in actively implementing carbon emission reduction.
