A Method for Calculating Carbon Flow Distribution Information Based on the Electric Energy Allocation Results of Power Grid Source Flow

The carbon flow distribution information in the power grid link is generated due to the electric energy allocation process of the carbon-bearing grid-connected source flow and is highly coupled with the electric energy allocation relationship of all connected source flows. To this end, this paper proposes a method for calculating carbon flow distribution information based on the electric energy allocation results of power grid source flow. Firstly, based on the electric energy flow information of the source-stream-related path chain set, calculate the carbon flow distribution information between any specified power source and load pair; secondly, based on the electric energy flow information of the source-related path chain set, the carbon flow direction information of carbon-bearing (including thermal power generation natural emission carbon and carbon market trading purchase carbon, etc.) power sources is calculated; thirdly, based on the electric energy flow information of the load-flow related path chain set, calculate the carbon traceability information of any specified load. The case study demonstrates that the method can accurately calculate the carbon flow distribution information reflecting the real-time operational status of the power grid, providing technical support for further optimizing the electric-carbon operation mode of the power grid.
