In the context of development of Carbon peak and Carbon neutral, the promotion of electric vehicles (EVs) provides a strong support for the realization of low-carbon goals. Firstly, this paper analyzes the coupling relationship between the scale of EVs, regional energy composition, Vehicle-to-Grid (V2G) technology and carbon emissions. Secondly, the district energy development path is constructed according to the development law of clean energy. Finally, based on the principle of system dynamics, a dynamic feedback model of the evolution of regional carbon emission trajectory due to the entry of V2G under the development of clean energy is established. This paper takes the data of a city in southwest China as an example to conduct dynamic evolution simulation, in which the development scale of EVs and the development path of clean energy are taken as the main variables to analyze the impact of EVs on regional carbon emissions under various scenarios. This paper also verifies the carbon emission reduction benefit of electric vehicles through sensitivity test. The above simulation results indicate that the development of clean energy has the most significant impact on carbon emission reduction, and V2G technology has huge benefits of carbon emission reduction.
