A method for carbon emission flow analysis in active distribution networks based on power flow tracking

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 optimization 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 emission 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 efficacy of the proposed method.
