The invention discloses a method for constructing a multi-time scale response capability evaluation model of an electric vehicle virtual power plant. According to the method, on the basis of fully considering a time sequence state including SOC and a charging and discharging state in an EVs evaluation process, four typical scenes under different response modes are extracted, g the single EV powerconstraint and available capacity under the continuous time section are analzyed, and a single and continuous time section response capability evaluation model of the single electric vehicle is proposed. On the basis, an EVPP multi-time scale response capability evaluation model containing day-ahead and intra-day correction is provided; the EVPP day-ahead response capability is evaluated by utilizing EVs state prediction data before the day; a specific regulation and control result is determined according to an EVPP regulation and control strategy comprehensively considering response time margin and state-of-charge margin indexes in the day, then a day-ahead response capability evaluation result is corrected, and dynamic updating of the EVPP response capability is achieved while a system regulation and control target is effectively tracked.
