Based on the Cooperative Game Strategy of Virtual-Thermal-IES Under the Electricity Carbon Trading

Under the " double carbon " goal, how to realize the rational and efficient use of renewable energy and reduce carbon emissions has become an important step in the transformation of low-carbon economy. At present, most of the studies are realized from the perspective of power utilization or power sharing, and do not consider the role of carbon emissions from thermal power output in the synthesis of methane.Aiming at this problem, this paper studies the electricity-carbon cooperation among virtual power plants, thermal power plants, and Integrated Energy Systems (IES). Firstly, it develops a multi-agent cooperative operation model involving virtual power plants, thermal power plants, and IES for energy and carbon trading. Secondly, based on Nash bargaining principles, it decomposes this model into two subproblems: maximizing the combined coalition benefits of multiple agents and determining the pricing for electricity-carbon trading, to solve for the trading volumes and prices. Finally, the effectiveness of the cooperative operation strategy among multiple agents is verified through numerical examples. The simulation results show that the virtual power plant and thermal power plant can improve the utilization rate of new energy and effectively reduce carbon emissions by forming an alliance with IES, so as to actively respond to the dual-carbon target.
