The varying carbon emission characteristics of distributed resources result in spatial-temporal differences in emission intensity at various nodes in the distribution networks.To effectively support low-carbon analysis and op-timization in distribution networks as well as low-carbon accounting and trading at the user side,a model for electricity-carbon coupling in active distribution networks is built.Using load flow tracking,quantitative analysis and research on the carbon emission flow in active distribution networks is conducted,incorporating carbon emis-sion costs into the economic costs of the distribution system.Aiming for the minimum total economic cost of the power system,simulation analysis is carried out using the IEEE 33-node test case,validating the feasibility and effi-cacy of the proposed method.
