Avaliação técnica e econômica da utilização de geração solar e recarga de veículos elétricos em universidades

Abstract

With the increasing electrification of the transportation section worldwide, the higher is the demand for charging infrastructure. Aiming to deal with this demand the present work performs technical and economic analyses to study the impacts of electric vehicles charging stations, more specifically at Universities. A real system is modeled and analyzed considering voltage profile, voltage imbalances, transformer overload and overcurrent in different scenarios, investigating the behavior of the system under those new conditions. Also, a procedure to define the maximum number of charging stations is proposed considering the limits of the above-mentioned variables of the system. Then, investment analysis techniques are used to evaluate the project. Even more, the insertion of solar energy in the campus is also considered integrated with the charging stations, using genetic algorithms to determine the best point to allocate the distributed generation based on the reduction of the system losses. In this case, a set of scenarios has been considered to better evaluate the integration of both technologies.
