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...

Study on Suppression of Voltage Fluctuation During Induction Motor Starting Using Volt–Var Control of Smart Inverter

Induction motor starting often causes voltage fluctuations due to high inrush current, which can impact system stability and power quality. To address this, smart inverters with power control functions and superconducting fault current limiters (SFCLs) have emerged as promising solutions for reducing voltage instabilit...
