Determining User's Indirect Carbon Emissions Considering Green Electricity Trading Decomposition

In order to guide the whole society to consume green power, under the background of carbon peak carbon neutralization, all localities actively organize and carry out market-oriented transactions of green power. Therefore, it is a key problem to establish the green electricity deduction mechanism purchased by the load, which is the key problem to promote the development of green power market. Based on dynamic carbon emission factors, this paper first establishes the carbon trajectory model of the whole system chain extending from the power generation side to the user side to provide accurate and reliable node carbon emission factors. Then a carbon emission flow tracing method is established from the user's point of view, and a carbon emission flow model considering the credit effect of financial green electricity trading on carbon emission measurement is proposed. Finally, the rationality and feasibility of the proposed method are verified by an example of IEEE-14 node.
