SOGI-FLL error-and-hold algorithm for improving the response in face of voltage sags and swells with a small computational burden

The Second Order Generalized Integrator–Frequency Locked Loop (SOGI-FLL) is a widely used and popular adaptive filter for estimating grid voltage parameters with minimal computational burden. However, it is vulnerable to voltage sag and swell faults, especially voltage sags that can significantly di...
