Analysis of the impacts of electric vehicle chargers on a medium voltage distribution network in Casablanca City

The transition to sustainable mobility has been one of the major challenges in recent years to mitigate global climate change, including the greenhouse effect directly linked to vehicle emissions. This article presents an analysis of the load and voltage profile and harmonic impact of integrating electric vehicles on medium voltage in an energy distribution network of an intermediate city, Casablanca, Morocco. By examining social, geographical, and technical aspects, it aims to determine the minimum infrastructure required for this specific case. Using MATLAB/Simulink software, a model of a 3.7 kW slow electric charger with AC/DC and DC/DC power converter is developed to study the integration of these vehicles into the energy distribution network of the city of Casablanca, Morocco. The simulation software analyzes the behavior of active and reactive power, voltage, and current. Additionally, the results indicate that the impact of this integration on the distribution system has led to a degradation of utility power factors and a slight decrease in the voltage profile of the network. By providing economic and environmental benefits to the city, this study helps establish the necessary procedures to define slow charging infrastructure in urban environments and evaluate its impact on the energy distribution network.
