Real-Time Transient Instability Identification in Power Systems using a PMU-Based EMS System
Modern power systems are confronted with operational challenges that increase the risk of transient instability. Existing Dynamic Security Assessment (DSA) tools have limitations, necessitating accurate and timely assessment of transient stability. To address this, a novel approach for real-time ide...
