  Establishing electrical parking lots will become more important by increasing
the use of electric vehicles (EVs). These parking lots not only can be seen as
high electrical power consumption loads which can cause the voltage drop at
feeders but also they can be used as electrical power plants that can help the
main power grid during the load peak hour or any congestion. Therefore, finding
an optimum place for the building of these lots, in which the deviation of the
voltage at the feeder, power loss in the grid, and cost be minimized, is
essential. In this paper, a new method of vehicle-to-grid reactive power
support (V2GQ) has been used to add the model of plug-in electric vehicle (PEV)
as one part of the objective function to find the optimum place of parking
lots. The non-sorting genetic algorithm II (NSGA2) is used here as an
optimization algorithm to find the optimum voltage profile based on the
location of parking lots. For validation of the purposed method, a 33-bus
standard distribution network has been studied.
