With the rapid growth of electric vehicle number and the acceleration of low-carbon transformation of the power grid,it is of great significance to promote the two-way flexible interaction between electric vehicles and the power grid for the construction of a new power system and the realization of the"dual carbon"goal.Based on this,this paper firstly summarizes three mainstream technologies of the current status on"Vehicle to Grid"and their application status at home and abroad.Secondly,from the three aspects:accelerating the consumption of new energy,improving the operation efficiency of generator sets and reducing the scale of power grid construction,the carbon reduction value of"Vehicle to Grid"is studied.Finally,an evaluation index is established from the four aspects:environmental benefit,economic value,reliability and social recognition.And the comprehensive benefit level of"Vehicle to Grid"is divided into different stages,in order to play a greater reference value in the new energy system.
