The invention discloses a quantitative evaluation method and system for adjusting capability of accessing an electric vehicle to a power grid, and the method comprises the steps: obtaining load data of a power grid side, electric vehicle parameters of a plurality of to-be-dispatched electric vehicles, and electric vehicle load characteristic parameters; constructing electric vehicle response power grid regulation capability quantitative evaluation indexes according to the power grid side load data and the electric vehicle parameters, performing group division on a plurality of electric vehicles to be dispatched to obtain a plurality of electric vehicle classes, determining comprehensive weights of the electric vehicle response power grid regulation capability quantitative evaluation indexes of the electric vehicle classes by using an entropy weight method, and calculating the electric vehicle response power grid regulation capability quantitative evaluation indexes. And performing evaluation according to the comprehensive weight of the electric vehicle response power grid regulation capability quantitative evaluation index and a preset evaluation method to obtain an evaluation result, so that power grid personnel can formulate a scheduling strategy according to the evaluation result, and performing quantitative evaluation on the electric vehicle access power grid regulation capability by considering the response potential of the electric vehicle. And the quantitative evaluation accuracy of the electric vehicle response power grid regulation capability is improved.
