摘要
With the increasing penetration rate of electric vehicles(EVs),EV demand response holds great significance for promoting the optimal and secure operation of the power system.This paper proposes an EV response capability assessment method that considers EV users’travel demands and the reliability of the cyber systems integrated into both the power grid and the transportation network.A novel framework for an integrated cyber-power-transportation system is proposed for the first time,and a reliability model for the cyber system is provided.A method is further proposed to calculate the state of an EV when it is plugged in,considering the reliability of traffic guidance information and the reliability of the release of such information.The degree of relaxation in the EV charging demand is proposed to reflect the user’s travel demand,based on which the EV response capability can be assessed.Extensive test results on a cyber-power-transportation system containing RBTS BUS6 and the Beijing transportation network are conducted to show the efficiency of the proposed method.The impact of cyber reliability on the EV trip and response capability is analyzed.
