Research on equilibrium strategies of multiple electricity prosumers under the coordinated mechanism of electricity and carbon markets
Recently,China is promoting the construction of high penetration renewable energy systems,which urgently needs to study a market-based trading mechanism that can reveal both the economic and environmental values of renewable energy.This paper constructs a game model of electricity and carbon trading among multiple electricity prosumers considering the electricity and carbon coordinated mechanism,solves the equilibrium price of the electricity-carbon coordinated market by using the Walrasian general equilibrium theory,reveals the effect mechanism of the electricity-carbon coordinated mechanism on the market equilibrium price and social welfare,and analyzes the impact of key parameters such as free carbon quotas and the number of prosumers on the market equilibrium.The results indicate that the electricity carbon coordinated mechanism can lower the carbon market price,improve the overall social welfare of prosumers,reduce the cost of purchasing carbon,and motivate prosumers to consume more renewable energy.Besides,the greater the number of prosumers,the more significant the economies of scale.Free carbon quota reduction will raise the equilibrium price of the carbon market,better reveal the environmental value of renewable energy power,and promote the coordinated development of the electricity and carbon markets.The study forms an electricity and carbon linkage trading mechanism for prosumers considering the environmental value of renewable energy,which provides theoretical and methodological support for the coordinated operation of the electricity and carbon markets.
