Phase-Locked Loop (PLL) With High-Pass Filter and Adaptive Control for Sub-Synchronous Oscillation (SSO) Mitigation in Weak Grids With Inverter-Based Resources

The increasing penetration of inverter-based resources (IBRs) has reduced system inertia and increased the susceptibility of weak grids to sub-synchronous oscillations (SSOs). Under low short-circuit ratio (SCR) conditions, grid-following converters may interact adversely with grid impedance; phase-locked loop (PLL) dy...
