SUMMARY:

The present study aims to conduct a comprehensive analysis of the challenges faced by urban electrical grids in the face of the massive charging of electric vehicles (EVs). In the current context of a society constantly focused on seeking sustainable solutions, electric mobility emerges as a promising alternative to mitigate greenhouse gas emissions and reduce dependence on fossil fuels. In the current scenario of electric mobility, the growing interest in electric vehicles as a viable response to environmental and energy challenges is evident. The increasing demand necessitates the need to manage the implications of massive EV charging on urban networks. In this context, this work describes the challenges related to electric mobility and its repercussions on urban electrical infrastructures, specifically associated with electrical impacts on power quality resulting from the connection of EVs to the grid. The results are based on simulations implemented in a Hardware-in-the-Loop (HIL) environment, highlighting operating points and conditions for the occurrence of electrical impacts from fast charging stations on the power quality components established by the PRODIST standard (Electricity Distribution Procedure). Finally, a new specific indicator is proposed, called the Electric Vehicle Charging Grid Impact Index (ECGII). The goal of the ECGII is to predictively assess, in stages prior to the installation of a new charger connected to the distribution network, the potential occurrence of impacts from EV charging. Thus, the ECGII index can be a tool for urban electrical network managers and planners, serving as a classifier to support strategies that optimize vehicle integration, ensuring energy efficiency and operational reliability. Therefore, in the context of the growing adoption of electric mobility, this work seeks to contribute with a method to support the management of challenges faced by urban electrical grids in scenarios of high insertion of potentially disruptive loads associated with EV charging infrastructure.
