Carbon Market Transaction Matching Study Based on Carbon Emission Flow Theory

The carbon emission flow analysis theory of power system provides a new idea for carbon emission calculation. According to the carbon emission flow theory, the carbon emissions based on responsibility sharing are obtained and the carbon trading demand of users is calculated first, then the future transaction matching method of the carbon trading market is proposed to adapt to different types of carbon trading methods. Take the IEEE 14 bus system as a case, this study calculates carbon emissions at different nodes to form carbon trading demand information. Under the constraints of trading volume and type, referring to the mature trading model of the electricity market, we adopted centralized bidding trading to design the carbon trading matching method. The results show that the design of the transaction matching method in the carbon trading market is reasonable, and users of each node based on the IEEE14 bus system can achieve the optimal market trading strategy through the new matching method.
