AB  - With the widespread implementation of distributed generation (DG) and the integration of soft open point (SOP) into the distribution network (DN), the latter is steadily transitioning into a flexible distribution network (FDN), the calculation of carbon flow distribution in FDN is more difficult. To this end, this study constructs a model for low-carbon optimal operations within the FDN on the basis of enhanced carbon emission flow (CEF). First, the carbon emission characteristics of FDNs are scrutinized and an improved method for calculating carbon flow within these networks is proposed. Subsequently, a model for optimizing low-carbon operations within FDNs is formulated based on the refined CEF, which merges the specificities of DG and intelligent SOP. Finally, this model is scrutinized using an upgraded IEEE 33-node distribution system, a comparative analysis of the cases reveals that when DG and SOP are operated in a coordinated manner in the FDN, with the cost of electricity generation was reduced by 40.63 percent and the cost of carbon emissions by 10.18 percent. The findings indicate that the judicious optimization of areas exhibiting higher carbon flow rates can effectively enhance the economic efficiency of DN operations and curtail the carbon emissions of the overall network.
