When facing elevated risks such as severe weather, live line repairs, sabotage, or public events near overhead lines, it is beneficial for microgrids to shift from a traditional economical operational strategy to a more resilient one. This resilient strategy is used selectively in response to heightened risks and aims to improve the microgrid’s ability to handle and recover from failures, ensuring continuous operation. This research focuses on optimizing the steady-state conditions of synchronous generator-based microgrids to enhance fault tolerance. Microgrids can better manage disturbances and sudden load changes by strategically adjusting the system’s operating conditions. Simulation results demonstrate that a resilient steady state improves stability, reduces fault vulnerability, and increases reliability
