The prompt fault recognition and isolation augment the grids' resiliency and improve its inclusive performance. A DC microgrid accomplishes solicitous attention worldwide due to the development of power electronic-based devices, its higher efficiency, and the advancement of various DC loads. The study reports the advantages and challenges associated with DC microgrid protection. Overcurrent-based relaying schemes can't provide such systems with the desired sensitivity and selectivity. The complexity in the protection strategy becomes prominent with ring-type DC systems, exclusively with high impedance faults. The study propounds a differential scheme to provide fast and reliable protection addressing the overcurrent relay limitations. A differential scheme may be a promising solution with improved data processing capacity and an advanced communication framework accessible in an available intelligent grid structure. The studied DC ring bus type microgrid is developed using PSCAD/EMTDC environment. The study tests the scheme's efficacy and finds it suitable for various instances, including different loading conditions and high impedance faults.
