This paper evaluates how the use of V2G technology has an important impact on the characteristic of the demand curve. Therefore, a study case is developed based on the characteristic of Bogota's (Colombia) demand curve and the statement of different scenarios of V2G participation. In order to determine when the EV battery is charging or injecting, 3 parameters were considered: Availability, State of Charge (SOC) and a TOU tariff. In addition, 4 behavior profiles were proposed for different types of vehicle owners with the objective of analyzing the sensibility of the demand curve in terms of number of owners with certain daily behavior. Finally, the results were contrasted by the load factor in each case, where it was shown that the impact on the demand curve depends mainly on the number of vehicles incorporated to the V2G scheme, demonstrating an improvement until a maximum number of vehicles.
