The increasing magnitude of the Electric vehicles (EV) as part of these global energy transition highlights the necessity to understand their effects of the power quality dispersion networks. This project investigates the distortions caused by power electronic converters in EV battery chargers, which can significantly degrade power quality. The emergence of single-phase intensive loads, such as private EV charging stations, complicates the operation of Low Voltage Distribution Networks. Given the growing adoption of EV, addressing these power quality issues is crucial. This study focuses on evaluating the impact of charging station on key power factors Limits, of particularization Total Harmonic Distortion and electric field. Using MATLAB and Power Simulation simulations, to be the project analyses the power quality impacts associated with EV charging. The results provide insight into the extent to which EV chargers influence power quality and highlight the potential challenges and solutions in integrating EV infrastructure into existing power dispersion systems.
