	abstract = {Wind farms are integrated with the power grid system to provide active and reactive power. Because in a wind farm, wind turbines (WTs) are highly coupled to their operating conditions, a central wind farm supervisory unit must take into account these conditions when producing power control references for each WT. The aim of this paper is to manage and control the active and reactive power of wind farms based on squirrel cage induction generators and back-to-back converters. The proportional distribution algorithm is used for distributing wind farm power to individual WTs. In addition, we consider the development of a local power management and control units for WTs. This is in order to extract the maximum available power from the wind, and to provide the active and reactive power predetermined by the transmission system operator, or to satisfy the grid code requirements considering Low Voltage Ride-through capability. The power dispatch strategy is to be used on all WTs using the distribution algorithm while ensuring the control loops using the proposed Active Disturbance Rejection Control strategy. The results demonstrate that the proposed strategies are efficient and can guarantee the safe integration of wind farms into the grid while respecting grid code requirements and power system stability. {\textcopyright} 2022, The Author(s).},

	abstract = {Wind energy conversion system (WECS) is composed of many non-linear power electronic sub systems, which contribute significantly in harmonic emissions that is a threat for the quality of electrical power. Hence, for a better integration of WECS in the electrical grid and in order to satisfy IEEE 519 standards, WECS must inject a quality power with a rate of total harmonics distortion (THD) that is less than 5\%. Multilevel Inverters are an emerging solution for having a perfect sinusoidal output voltage with minimum harmonic content and lower switching losses than the two-level inverter so that only a smaller filter size is required. Thus, in this paper we are presenting a significantly improved results of the reduction of the grid injected current THD using three types of inverters (two-levels, three-levels NPC, and five-levels H-bridge cascade) for a WECS and comparing the THD performances of using each of the studied inverter.

	abstract = {In the interconnected power systems, there must always be a balance between the amount of electricity produced and the amount of electricity consumed in order to keep the grid frequency stable and nearby to its nominal value. Therefore, any change in consumption can lead to imbalance, instability, load shedding and system frequency disturbances. With the increase of wind energy penetration level in the electrical network, it has become necessary to make wind generators participate in frequency regulation. The fundamental objective of this research paper is to investigate the ability of wind turbine at variable speed equipped with doubly fed induction generator (DFIG) to contribute in the grid frequency regulation. For the purpose of the contribution in the frequency regulation, the wind turbine system must inject a supplementary power support into the electrical network. To do that, two control strategies are adopted: the first one is the synthetic inertia control which uses the kinetic energy reserved and stocked in the turbine and generator rotors of the wind system. The second one is the droop frequency control which includes the deloading method that allows to the VSWT to create a certain reserve active power. Then, each of these control techniques is implemented and their performances are evaluated in case of frequency variation. Moreover, the control structure that uses the combination of these two techniques is also implemented and studied. The active disturbance rejection control strategy (ADRC), the classical PI controller and the polynomial RST controller have been adopted to command the rotor side converter (RSC) of the DFIG which allows it to provide, in case of frequency fault, a support for the power system into the grid by adjusting the rotor speed. The performance of these controllers are tested and compared and the simulation is performed by MATLAB/Simulink simulation software. {\textcopyright} 2021, International Journal of Renewable Energy Research.

	abstract = {According to the recent grid codes, wind turbine systems (WTSs) are required to stay connected to the grid during grid faults and provide reactive power to support the grid. Therefore, this paper proposes a noncontrolled fault current limiter (NCFCL) with reactive power support for transient stability improvement of DFIG-based WTSs under grid faults. The proposed NCFCL is based on a nonsuperconducting reactor located in the rotor side. The NCFCL considerably limits the rotor and stator overcurrents and improves the transient stability of the doubly fed induction generator (DIFG). In addition, the proposed strategy reduces DC-link overvoltage and electromagnetic torque oscillations and also provides reactive power to the grid to support the grid voltage recovery. In this way, the fault ride-through (FRT) requirements of the latest grid codes can be fulfilled without affecting the DFIG stability in normal operation. Simulation studies using MATLAB/Simulink-2019a are performed on a 2-MW DFIG-based WTS to confirm the effectiveness and feasibility of the proposed FRT strategy. Simulation results reveal that the proposed strategy provides better performance compared to the crowbar protection to improve the FRT capability. {\textcopyright} 2021 John Wiley \& Sons Ltd.},

	abstract = {A novel and robust active disturbance rejection control (ADRC) strategy for variable speed wind turbine systems using a doubly fed induction generator (DFIG) is presented in this paper. The DFIG is directly connected to the main utility grid by stator, and its rotor is connected through a back-to-back three phase power converter (AC/DC/AC). Due to the acoustic nature of wind and to ensure capturing maximum energy, a control strategy to extract the available maximum power from the wind turbine by using a maximum power point tracking (MPPT) algorithm is presented. Moreover, a pitch actuator system is used to control the blades{\textquoteright} pitch angle of the wind turbine in order to not exceed the wind turbine rated power value in case of strong wind speeds. Furthermore, the rotor-side converter is used to control the active and reactive powers generated by the DFIG. However, the grid-side converter is used to control the currents injected into the utility grid as well as to regulate the DC-link voltage. This paper aims to study and develop two control strategies for wind turbine system control: Classical control by proportional integral (PI) and the proposed linear active disturbance rejection control (LADRC). The main purpose here is to compare and evaluate the dynamical performances and sensitivity of these controllers to the DFIG parameter variation. Therefore, a series of simulations were carried out in the MATLAB/Simulink environment, and the obtained results have shown the effectiveness of the proposed strategy in terms of efficiency, rapidity, and robustness to internal and external disturbances. {\textcopyright} 2020 Hammadi Laghridat et al.},

	abstract = {The Three-Level Neutral-Point-Clamped (3L-NPC) inverter fed Permanent Magnet Synchronous Motor (PMSM) drive is an attractive configuration for high performance Electric Vehicle (EV) applications. For such configuration, due to their high performances, the Finite-Control-Set Model Predictive Control (FCS-MPC) is a very attractive control solution. The FCS-MPC scheme is based on the prediction of the future behavior of the controlled variables using the dynamic model of PMSM and the discrete nature of the 3L-NPC inverter. However, the parametric uncertainties and time-varying parameters affect the FCS-MPC algorithm performances. In this paper, robust FCS-MPC controls based on "dynamic error correction" (DEC) and "modified revised prediction" (MRP) are proposed to improve the FCS-MPC robustness without affecting the controller performances and complexity. The proposed strategies are improved also by multiobjective (MO) algorithm optimization and computation delay compensation. The simulation results included prove the performance in robustness and efficiency of the proposed robust FCS-MPC-DEC. {\textcopyright} 2020 Abdiddaim Katkout et al.},

In first place, a modelling of wind turbine and DFIG is presented. Then, the PI controller, the Backstepping approach and a maximum power point tracking (MPPT) strategy used to extract the maximum of power during the conversion are developed. Simulations results show significantly improved performances of the proposed backstepping approach over the Proportional-Integral controller, in terms of dynamic response, disturbance rejection, and robustness against parametric variations.

The control is provided by the linear active disturbances rejection control, (LADRC) controller, which has several benefits over the conventional PI controller such as the estimation and compensation in real time of the internal and external disturbances, which can be summarized in the parameters uncertainties. To ensure the performances and achieve the advantages of the LADRC controller, in case of primary frequency control, the results are compared with the conventional PI by a simulation in MATLAB/Simulink. The results obtained have shown that the LADRC controller is much more efficient compared to a conventional PI controller in terms of control. Finally, the primary frequency control can be better applied with this type of controller which ensures a good dynamic frequency support and a reduction of the frequency variations. {\textcopyright} 2017 Praise Worthy Prize S.r.l. - All rights reserved.},
