Abstract
Electric vehicles (EVs) are capable of providing frequency regulation services through Vehicle-To-Grid (V2G). However, EV batteries are different from conventional energy storage systems in the sense that they are originally power load, not only for energy sources. EV owners may require that their charging requests are satisfied while their vehicles even participate in the V2G operation, and therefore, this paper proposed a V2G frequency regulation method in an isolated microgrid considering EV charging requests. The paper presents assumptions necessary for the proposed method and describes a state-of-charge (SOC) management plan and a concept of critical SOC for EV charging requests. In addition, V2G operation scheme for frequency regulation is defined and classified according to the charging requests. Finally, the simulation results using PSCAD/EMTDC and analyses are presented to verifying the effectiveness of the proposed methods.
