Abstract

The rapid growth of electric vehicle charging in urban areas imposes increasing stress on low- and medium-voltage distribution networks, leading to voltage deviations, higher current loading, and harmonic distortion. This paper investigates dynamic power redistribution among multiple EV charging stations as a means of mitigating these effects. A detailed simulation model of a residential-commercial distribution feeder, including EV chargers and power electronic interfaces, was developed in MATLAB/Simulink. Single-phase and three-phase charging scenarios, with and without LCL filters, were analysed. The proposed dynamic control strategy adapts charging currents according to available feeder capacity and real-time network conditions. Simulation results show that dynamic power redistribution improves voltage profiles, reduces peak loading of lines and transformers, and decreases total harmonic distortion compared to conventional fixed-power charging. The paper confirms that coordinated and adaptive charging can significantly increase the hosting capacity of distribution networks for EV without immediate grid reinforcement.
