In the realm of distributed energy resources, Doubly-Fed Induction Generator (DFIG)-based Wind Energy Systems are pivotal technologies. However, integrating them into the grid poses challenges like ensuring Low Voltage Ride Through capability and enhancing energy quality. Advancing DFIG control techniques is crucial to address these challenges. This study provides a customized Linear Quadratic Regulator (LQR) control mechanism along with gain scheduled strategy, applied on a state equation model for the DFIG’s Rotor-Side Converter. Stability results are presented. The results demonstrate the effectiveness of the proposed controller in the presence of noise compared to LQR with fixed gain.

摘要

In the realm of distributed energy resources, Doubly-Fed Induction Generator (DFIG)-based Wind Energy Systems are pivotal technologies. However, integrating them into the grid poses challenges like ensuring Low Voltage Ride Through capability and enhancing energy quality. Advancing DFIG control techniques is crucial to address these challenges. This study provides a customized Linear Quadratic Regulator (LQR) control mechanism along with gain scheduled strategy, applied on a state equation model for the DFIG’s Rotor-Side Converter. Stability results are presented. The results demonstrate the effectiveness of the proposed controller in the presence of noise compared to LQR with fixed gain.
