Assessment of EV Response Capability Considering User’s Demand Xu Sun, Yanli Liu

Abstract

Electric vehicle (EV) is an important demand response resource, which can optimize the operation of power grid by load shifting and vehicle to grid (V2G). Effective assessment of EV response capability is of great significance for optimizing grid operation and improving grid safety. Therefore, this paper proposes an EV response capability assessment method considering EV user’s demand. Firstly, the state of EV when plugged in is calculated based on trip chain. Then, an EV charging strategy is used to minimize load variance, considering EV user’s demand. Finally, the degree of EV charging demand relaxation and an EV response capability assessment method considering EV user’s demand are proposed. Case studies on power-transportation coupling system containing RBTS Bus6 and Beijing transportation system show that the proposed EV response capability assessment method is effective.
