Research on a Model for Load Flow Tracking and Allocation of Unit Carbon Emissions

In this study, a novel model for the allocation of car-bon emissions between power generation units and loads in an electrical power system is proposed. The model decomposes the carbon emission structure of the power system into key components, aligning them with corresponding components of the electrical energy determination structure and carbon emission flow calculation indicators. This approach enables the characterization of the distribution of carbon emission components within the system. Quantitative allocation of carbon emissions resulting from system network losses is achieved through load flow tracking, ultimately providing real-time apportionment results for the carbon emissions of the system. The feasibility and accuracy of the model are validated through a case study on the IEEE 14-bus standard nodes.
