Abstract
This research analyzes the line power losses and voltage variation that are caused by the V2G system penetration in the study power network. The V2G system is demonstrated as mathematical model, and simulated by the computer program for investigating the relationship among the line power losses, voltage variation, and probability of the V2G location. The 3 cases study of the V2G penetration are presented and assigned to describe the behavior of charging and discharging the amount of active power by the V2G system. The simulation results show large amount of line power losses and voltage variation issues can be found in case of the congestion of discharging power is closely occurred to the distribution transformer and the end of power distribution network. However, these issues can be overcome by distributing the charging or discharging location of the V2G system. The relationship earlier mentioned can clearly depict by the proposed variation index.
