A DC micro-grid is an emerging power distribution system that integrates various renewable energy sources, energy storage devices, and loads within a localized area. Ensuring the reliable and safe operation of a DC micro- grid is of paramount importance. This abstract provides an overview of a DC micro-grid protection scheme designed to safeguard the system against faults, disturbances, and abnormal operating conditions. For detection of fault and location estimation in DC micro-grids with various renewable energy sources (RESs) such as PV, wind, and batteries, a new differential protection technique based on the relay's sensitivity is proposed in this study. When a failure occurs, it could result in undesired resource disconnections and render the system unreliable. The suggested method successfully identifies faults in the DC micro-grid, according to simulation results.
