Analysis of Carbon Emission Flow in Hybrid Power Market Based on Cooperative Game Theory

In the context of low carbon power development, green power market-based trading has gradually developed, and a new hybrid power market situation has emerged with the coexistence of bilateral green power trading and pool trading. Carrying out the whole link carbon emission accounting of the hybrid power market under the new situation is of great significance for promoting the development of low carbon power. Aiming at the limitation of the current carbon flow analysis method applied in the hybrid power market, this paper proposes a carbon flow tracking method of the hybrid market based on the cooperative game theory. Using the Shapley value method to achieve a reasonable apportionment of the carbon flow rate of the network loss between the transactions, and then decoupling the affiliate transactions from the bilateral transactions. The carbon emission components of each load within each trade can be obtained by utilizing the network matrix-based carbon flow tracking method, and then the load side carbon emission distribution is obtained by summing the carbon emission flow components of each load. Finally, the feasibility and correctness of the proposed method are verified by the IEEE14 node arithmetic example.
