“…The control of the DFIG by stator flux orientation [14] stator voltage [15] or air gap flux [16] is a technique synthesized by assuming that the grid voltage is ideal and the stator flux is constant or vary very slowly. However, stator flux introduces high nonlinearity into the system during network fault.…”

This paper proposes a novel Doubly Fed Induction Generator (DFIG) control approach using an optimized set of observers. Firstly, an Adaptive Disturbance Rejection Scheme (ADRS) Model Reference Adaptive System (MRAS) observer is applied to estimate generator speed. Secondly, a Fuzzy Logic MPPT controller is designed to optimized power conversion. Finally to achieve the overall sensor-less control, speed, current and DC-voltage control are achieved using a novel version of perturbation observer while taking into account the power loss in the system. The technique is evaluated for a 1.5MW DFIG under variable wind speed, measurement noise, grid voltage dip and parameter variation and compared with the conventional PI-controller.

Wind speed variations affect the performance of the wind energy conversion systems (WECSs) negatively. This paper addressed an advanced law of the backstepping controller (ABC) for enhancing the integration of doubly fed induction generator (DFIG)-based grid-connected WECS under wind range of wind speed. This enhancement was achieved through three control schemes, which were blade pitch control, rotor-side control, and grid-side control. The blade pitch control was presented to adjust the wind turbine speed when the wind speed exceeds its rated value. In addition, the rotor and grid-side converter controllers were presented for improving the direct current link voltage profile and achieving maximum power point tracking (MPPT) under speed variations, respectively. To evaluate the effectiveness of the proposed ABC control, a comparison between PI and sliding-mode control (SMC) was presented, considering the parameters of a 1.5 MW DFIG wind turbine in the Assilah zone in Morocco. Moreover, some changes in the DFIG parameters were introduced to investigate the robustness of the proposed controller under parameter uncertainties. Simulation results showed the capability of the proposed ABC controller to enhance the performance of the DFIG-WECS based on variable speed and variable pitch turbine, at both below and above-rated speed, leading to an error around 10−3 (p.u), with an ATE = 0.4194 in the partial load region; in terms of blade pitch control, an error of 2.10−4 (p.u) was obtained, and the DC-link voltage profile showed a measured performance of 5 V and remarkable THD value reduction compared to other techniques, with a measured THD value of 2.03%, 1.67%, and 1.46% respectively, in hyposynchronous, hypersynchronous, and pitch activation modes of operation. All simulations were performed using MATLAB/SIMULINK based on real wind profiles in order to make an exhaustive analysis with realistic operating conditions and parameters.
