With increasing number of electric vehicles and electric vehicle charge stations, the question that if existing infrastructure of distribution system will meet new requirements has gained great importance. Mutable load profiles of distribution system and charge stations makes engineering analyses more sophisticated. In this study, some probabilistic analyses are carried out in a local distribution system in order to demonstrate effects of electric vehicle loads on the system parameters. Analysis studies have beed carried out on the model which is based on real data. Conventional and electric vehicle loads are forecasted in order to determine the effects of electric vehicle charge stations on voltage profile changes and transformer loading. Results are presented as comparative figures for different years studied.
