Abstract: By enriching the trading methods in the electricity market,the level of new energy consumption can be effectively improved.In view of the characteristics that the existing electricity market cannot effectively control carbon emissions,this paper proposes a power market clearing method that takes into account dynamic carbon emissions,and dynamically transfers the carbon emission cost of thermal power to the electricity price,so that some power generation rights are transferred to new energy sources. At the same time,when energy abandonment occurs,a price factor is introduced to replace the quotation for energy abandonment units,and the secondary clearing of the power market is carried out,which deeply promotes the development of new energy sources and balances the income of the transferee of power generation rights with an incentive compatibility mechanism. Using the improved IEEE 30 node system for simulation verification,the power market trading mechanism proposed in this paper can effectively reduce the carbon emissions of thermal power units and promote wind and solar energy consumption,which verifies the effectiveness of the method.
