Enhancement of Renewable Power System Protection Reliability Using a Superconducting Fault Current Limiting Circuit Breaker (SFCL-CB)

The proliferation of inverter-based resources (IBRs) and energy storage systems in power grids has led to a decline in the short-circuit ratio (SCR) and reduced fault current magnitudes, compromising the reliability of conventional overcurrent relays (OCRs) and creating protection blind zones. To resolve these vulnerab...
