Optimal allocation of parking lots bi-directional electric vehicle to improve voltage profile of smart distribution networks

Due to the increasing use of electric vehicles, the need to establish electrical parking lots is essential. These electrical parking lots have high electrical power consumption, by the same token, they leaving adverse effects on the smart power grid, not the least of which is voltage drop at the connection point to the network due to the excess power consumption.In this paper, by using a new method of vehicle-to-grid reactive power support (V2GQ) for implementation of the parking lot electrical vehicle (PEV) in the smart grid (SG) environment, the optimal placement method, which is base on genetic algorithm (GA), for improving voltage profile is presented. The main advantage of the proposed V2GQ technology over the conventional V2G technology is that the former does not discharge the PEV batteries. Thus, the V2GQ sustains the battery lifetime, which is of the highest customer priorities. Finally, for validation of the purposed method, a 33-bus standard distribution network is has been studied.
