Abstract

In this work of Scientific Initiation (IC), a study was carried out on the charging of electric vehicles in the electricity distribution network and the impacts of connections in the system. The impacts are analyzed in terms of changes in system load curves (feeders), nodal stress behavior and losses in the distribution network lines. To this end, a vehicle loading model will be developed in the electric power distribution network, using a metaheuristic Differential Evolution technique. It is a non-linear programming problem involving variables of a stochastic nature. Each solution to the problem, obtained through the algorithm Differential Evolution, will be evaluated by a function that seeks to minimize as electrical losses of the system, subject to the technical, operational and physical restrictions of the electrical system. The studies are based on the electric power distribution systems available in the literature. The work was developed in stages, having been developed in this first work of the CI. (AU)
