IET Power Electronics, Volume 19, Issue 1, January/December 2026.This study proposes a parallel observation deviation‐coupled linear active disturbance rejection control (PODC‐LADRC) strategy optimized by a pigeon‐inspired optimization algorithm to mitigate asymmetric aerodynamic loads in large‐scale wind turbines. By utilizing a decoupled observation architecture, the proposed method reconstructs total disturbances

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.This paper investigates local oscillations caused by interactions between grid‐forming converters and frequency‐sensitive induction motor loads. A unified small‐signal model and frequency‐domain analysis reveal that high load factors and low motor inertia can lead to weakly or negatively damped oscillation modes.

A Nonlinear Three-Phase Phase-Locked Loop Based on Linear Active Disturbance Rejection Controller
IEEE Access, 2017 Three-phase phase-locked loops (PLLs) are the most widely used synchronization components in power systems. For common PLL algorithms, there is a tradeoff between the filtering capability and dynamic response.
