N2 - This paper presents a simulation-based study of a multi-source DC microgrid integrated with a supercapacitor to enhance DC bus voltage stability. The model incorporates a photovoltaic (PV) array with a P&O algorithm-based boost converter, a permanent magnet synchronous generator (PMSG) driven wind turbine, AC grid support via a bidirectional voltage source converter (VSC), and a supercapacitor. The system is tested under varying solar irradiance and load conditions. Simulation results in MATLAB/Simulink show that the supercapacitor significantly improves voltage regulation and power quality, reducing voltage ripple by 96.8% for resistive loads and 97.6% for RL loads, while mitigating transient instability. The findings validate the effectiveness of the proposed microgrid configuration and provide practical insights into voltage enhancement strategies for multi-source DC microgrids.
