This paper presented a method for evaluating V2G load curves by using the chargingand discharging locations of electric vehicles to evaluate the impact of loads generated by thecharging and discharging of electric vehicles on the power grid. Considering the estimated EVs'share, the EVs' discharge power was evaluated to reflect both the nature of the arriving vehicle inthe morning and the SMP plan after establishing an assumption that the electric vehicle arrived atwork in the morning and the electric vehicle arrived at home in the afternoon for each of thecharging/discharging place, which is the work and home of electric vehicles in the city. Afterevaluating the V2G load for each charging/discharging power type for the EVs charging strategy,which takes into account both the natures of the vehicle arriving at home in the afternoon, theTOU charge system, and the characteristics of the vehicle arriving at work in the morning andthe SMP charge system, it was evaluated by comparing the impact assessment on the grid byadding the existing load. The results of this paper provide an accurate understanding of theimpact of EVs' charging and discharging loads on the power grid. The results should supportestablishing an EV charging and discharging load management program to control power gridsoverload with appropriate SMP and TOU charges.
