Research on carbon flow tracking method for distributed energy stations based on power grid trends

In the context of "carbon neutrality" and "carbon peaking", the accuracy of carbon emission control for distributed energy stations is becoming increasingly high, and it is urgent to propose a carbon flow tracking method for distributed energy stations. On the basis of power system power flow theory, this article proposes a calculation method for carbon flow on load nodes and connecting branches based on the relationship between system power flow and carbon flow. The correctness of this method is verified by an IEEE 14 node example. The results indicate that this method can clearly identify branches with high carbon flow rates and areas with high carbon emissions, and provide reasonable emission reduction planning plans.
