摘要
当前,我国正在推进以新能源为主体的新型电力系统建设,迫切需要研究可同时揭示新能源电力经济价值和环境价值的市场化交易机制.本文构建考虑电碳协同机制的多电力产消者间电碳交易博弈模型,采用瓦尔拉斯一般均衡理论求解电碳协同市场均衡价格,揭示电碳协同机制对市场均衡价格和社会福利的作用机理,并分析免费碳配额及产消者数量等关键参数对市场均衡的影响.结果表明电碳协同机制能够降低碳市场均衡价格,提升产消者的整体社会福利,减少购碳成本,激励产消者更多地消纳绿色电力,且产消者数目越多,规模经济效益越显著;免费碳配额缩减将提升碳市场均衡价格,更能揭示新能源电力的环境价值,推动电碳市场协同发展.该研究形成了考虑绿电环境价值的产消者电碳联动交易机制,为电碳市场协同运行提供理论方法支撑.
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 electricitycarbon 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.
