[0003] The invention patent with application number 202311429683.8 discloses a carbon flow emission tracking and allocation method based on the electricity-carbon coupling network flow, which is characterized in that it includes the following specific steps: Step S1: Establish an electricity-carbon coupling network flow calculation model based on the electricity-carbon coupling characteristics; Step S2: Establish a low-carbon system network flow model with the minimum active network loss carbon emission as the objective function: Step S3: Determine the power distribution of the power grid based on the flow calculation results, and accurately track and trace the specific flow direction of carbon emissions; Step S4: Based on the principle of flexible applicability, allocate real-time carbon emissions of the power system.

[0004] The application aims to solve the following three problems: "At present, carbon emission accounting at the macro level starts from macro data and is calculated based on the total energy consumption in a year. It has the advantages of simple calculation, easy use, and accurate results. However, its calculation results have a certain lag and are too rough.
