Control System Based on DOB for Island Mode Operation of DFIG

This paper introduces a control system for Doubly Fed Induction Generator (DFIG) based on a Disturbance Observer (DOB) for island mode operation. The proposed control system is validated through experiments, confirming its effectiveness in maintaining stable operation during island mode. The system responded efficiently to variations in wind speed and load conditions, demonstrating the efficacy of the implemented control scheme. The proposed control system unifies the design approach for both the inner and outer loops of the cascaded control system structure, simplifying implementation and parameter tuning.
