Under the background of dual carbon strategy, in order to promote the construction of a new round of clean, low-carbon, safe and efficient new energy system in China, a virtual power plant optimal scheduling strategy method is proposed considering electric vehicle charging and discharging technology under the green certificate carbon trading interaction mechanism. Firstly, the mathematical model of virtual power plant and load side response model are established, and the adjustable upper and lower limits of cluster electric vehicles are predicted. Secondly, considering the carbon quotas and green certificate quotas of electric vehicles, the ladder type carbon trading model and green certificate trading model are established. Based on the conversion coefficients of the two mechanisms, the green certificate carbon trading interaction mechanism is designed, and the optimal scheduling model is constructed with the goal of minimizing the comprehensive cost of virtual power plants. Finally, calculation results show that the proposed model can realize the economy and low-carbon operation of virtual power plant. And the impact of electric vehicle charging and discharging mode and penetration rate, carbon trading price and green certificate trading price on virtual power plant operation are verified and analyzed.
