DC microgrids offer a simpler and more efficient alternative to AC microgrids, rendering them increasingly appealing for power distribution. However, protecting zonal DC microgrids with conventional protection methods proves to be challenging due to bidirectional power flow. In this regard, this paper suggests a current-based protection algorithm aimed at overcoming the shortcomings of conventional protection strategies for zonal DC microgrids. The proposed method identifies faults by utilizing the $(I/\vert I\vert)$ characteristics observed by IEDs located at the sending and receiving ends of the line. The system is evaluated on a 600 V zonal DC microgrid emulated in the MATLAB Simulink software, encompassing diverse instances such as Internal faults, External faults, close-in faults, noisy environments, and load switching. The simulation outcomes confirm the efficacy and validity of the suggested protection strategy.
