Wind Power Production based on DFIG: Modeling and Control by ADRC

Abstract

This paper presents the modeling and the control of the DFIG (Dual Fed Induction Generator) used in the wind power production. The model investigated in this paper is based on the different components that make up the wind energy conversion systems namely Turbine, DFIG, Back to Back Converters and Filter. The proposed control is known as the ADRC (Active Disturbance Rejection Control) which is used to ensure the maximum power extraction from the WTF (Wind Turbine Farm). The use of this ADRC provide also the regulation of the reactive power injected to the grid. This control strategy is based on the ESO (Extended State Observer) which estimate in real time the different disturbance affecting the system. The various performances of the proposed system are tested by numerical simulation carried out from MATLAB/SIMULINK software. The obtained results are analyzed in terms of references tracking, robustness and disturbance rejection.
