Abstract :Governments and leading corporations all over the world are now focusing their efforts on transitioning the transportation sector to a much more energy-efficient and less polluting model. Consequently, electric vehicles (EV) have experienced remarkable progress in recent years and are becoming an increasingly popular choice among consumers. This technological advance, coupled with roadmaps for the near future and new regulations, explains the exponential increase in EV sales worldwide. Therefore, in terms of the electric power systems to which the EV charging stations are connected, a completely unforeseen scenario arises. The main objective of this paper is to evaluate this future scenario, considering as a case study an industrial distribution network with the addition of EV charging stations based on different technologies and power levels. For this purpose, a typical electrical system developed by IEEE is taken as a basis and modified according to recent international standards, and subsequently, the model is quasi-dynamically simulated using DIgSILENT PowerFactory software. To develop a realistic model, the main characteristics of EV charging infrastructures are examined. Results of power flows and voltage profiles throughout one day are analyzed and discussed to identify the challenges that need to be addressed considering the widespread adoption of EVs. Thus, early verification of whether these electrical systems are ready to support increased demand for this type of transport vehicle is carried out.
