The integration of Electric Vehicles (EVs) into power grids introduces complex challenges, including load variability, voltage instability, and transformer aging. This paper proposes a simulation framework to analyze EV-grid interactions using a stochastic model of charging behavior, integrated with renewable energy sources (REzS). A modified IEEE 30-bus system is simulated in MATLAB/Simulink under varying EV penetration levels (10%, 30%, 50%), comparing uncontrolled charging with smart charging. Results indicate a 12–18% voltage deviation in residential zones during peak hours under uncontrolled charging, mitigated by dynamic pricing algorithms. Furthermore. The study highlights the need for adaptive grid management policies to accommodate future EV adoption.
