The use of electric vehicles for public transportation is a practice that has spread widely in recent years, in response to the needs ofreducing global polluting gases emissions and decrease vehicle ownership. However, nowadays some issues need to be addressedto provide this type of services with electric vehicles, such as the low-profit margins that can be achieved by the fleet operators.This paper addresses this issue giving to the public EVs the feature of providing power to the electrical network. Hence, a controlsystem based on optimization is proposed to perform profitable management of the charge and discharge of the EVs that are usedto provide public transport services by an operator, which also have the possibility of delivering power to the electrical network.Furthermore, this control system will also take into account the batteries wear cost.
El uso de vehículos eléctricos para transporte público es una práctica que se ha extendido ampliamente en los últimos años, enrespuesta a las necesidades de reducir las emisiones globales de gases contaminantes y disminuir los vehículos de uso privado. Sinembargo, hoy en día es necesario superar algunos retos para proporcionar este tipo de servicios con vehículos eléctricos, como losmárgenes de baja ganancia que pueden tener los operadores de la flota. Este documento aborda este desafío, dando al EV públicola función de proporcionar energía a la red eléctrica. Por lo tanto, se propone un sistema de control basado en la optimizaciónpara realizar una gestión económicamente rentable de la carga y descarga de los EV que se utilizan para proporcionar servicios detransporte público por parte de un operador, los cuales también tienen la posibilidad de entregar energía a la red eléctrica. Además,este sistema de control también tendrá en cuenta el costo de desgaste de las baterías.
