This study establishes a hybrid microgrid model integrating a Doubly Fed Induction Generator (DFIG), a photovoltaic (PV) array, and a battery energy storage system, and proposes a coordinated control framework. The DFIG regulates DC‐bus voltage through the grid‐side converter and performs maximum power tracking via the rotor‐side converter, while the ...

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
