The widespread integration of wind energy poses numerous challenges, including ride-through capability issues, stability concerns, and power quality issues within the utility grid. Additionally, the inherent non-linear nature of wind energy systems, coupled with internal dynamics like model uncertainties, non-linearities, parametric variations, modeling errors, and external disturbances, significantly impacts system performance. Therefore, developing a robust controller becomes imperative to address the complexity, non-linearity, coupling, time variation, and uncertainties associated with wind energy systems, aiming to enhance transient performance in the presence of external and internal disturbances. The research presented in this manuscript focuses on devising a robust control scheme for a grid-tied Permanent Magnet Synchronous Generator (PMSG) wind turbine. The objective is to improve the wind turbine's performance under both normal and abnormal grid conditions. The innovation in Active Disturbance Rejection Control (ADRC) lies in its capacity to offer robust, adaptive, and disturbance-rejecting capabilities without relying on precise mathematical models. This quality makes ADRC a valuable and innovative tool for addressing challenges in complex and dynamic real-world applications where system parameters evolve over time. The wind energy system is inherently non-linear, time-varying, cross-coupled, and highly uncertain. It is also susceptible to parameter uncertainties, parametric variations, and external grid disturbances, all of which significantly influence its performance. The effectiveness of the proposed control scheme is validated to enhance ride-through capability and extract maximum power under internal disturbances, external grid disturbances, and parametric variations. To assess the proposed controller's efficacy, a comparative analysis is conducted using the Integral Time Absolute Error (ITAE) index for all abnormal grid disturbances. This analysis is performed in comparison to a Proportional Resonant Controller and a PI controller, providing evidence of the proposed controller's effectiveness. In summary, the incorporation of an Active Disturbance Rejection Controller emerges as a promising solution for enhancing the Low Voltage Ride-Through (LVRT) and High Voltage Ride-Through (HVRT) capabilities of grid-tied Permanent Magnet Synchronous Generator (PMSG)-based wind energy systems.
