Microgrids (MGs) are revolutionizing modern power systems by enabling decentralized energy production, renewable integration, and enhanced grid resilience. However, the increasing complexity of MGs, particularly with integration Distributed Energy Resources (DERs), poses significant challenges for traditional protection schemes. This study addresses coordination Directional Overcurrent Relays (DOCRs) in MGs through a Mixed-Integer Linear Programming (MILP) model. The main contribution is MILP model that optimizes relay settings, including Time Multiplier Settings (TMS) standard characteristic curves, to minimize tripping times, while ensuring selectivity. Another key this work both IEC IEEE which enhances performance compared using single standard. was tested on benchmark microgrid, results demonstrated improvements fault-clearing times across various operational modes. By leveraging advanced optimization techniques diverse contributes development resilient efficient microgrids, reliable operation under varying fault conditions DER penetration.
