“…To ensure the accurate integration of the WEC-System with the utility grid, the regulation of active and reactive powers is needed as well as the synchronization of voltage and frequency. In this context numerous publications are found in literature as, in [3], the authors proposed an indirect vector control of a Squirrel Cage Induction Generator wind turbine where the objective is to control the DC-bus voltage and the reactive power by using the classical Proportional Integrator (PI) controller, authors in [4] used the Sliding Mode Control to drive the WEC-System based on a SCI-Generator, authors in [5] proposed a Fuzzy Logic Control of a variable speed cage machine wind generation system, and, in [6], the authors have used the Backstepping technique, Furthermore, additional types of controllers were also considered for squirrel cage-based WEC-Systems as cited in [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Nevertheless, another controller appeared in the last 10 years and it is used for the control applications in several area; this controller is known as the Active Disturbance Rejection Controller (ADRC); it is proposed by Jingqing Han [10].…”

“…Nevertheless, another controller appeared in the last 10 years and it is used for the control applications in several area; this controller is known as the Active Disturbance Rejection Controller (ADRC); it is proposed by Jingqing Han [10]. However, to the authors' best knowledge, very few publications are available in the literature that address the issue of controlling Wind Energy Conversion systems, where in [11] the authors proposed the control of a wind system based on a DFIG by the ADRC technique and in [12] the authors discussed the control of a direct driven wind turbine based on Permanent Magnetic Synchronous Generator by ADRC, but for the WEC SCI-Generator the application of this control cannot be found. The main advantage of this controller lies in the real time rejection of internal and external disturbances based on an extended state observer (ESO).…”

This paper aims at contributing to the modeling and control of a variable speed Wind Energy Conversion System (WEC-System) based on a Squirrel Cage Induction Generator (SCI-Generator). The connection between the SCI-Generator and the main utility grid is achieved by back-to-back three phase power converters (Generator and Grid Side Converters). A new control strategy named the Active Disturbance Rejection Control (ADRC) is proposed and utilized to control the Wind Energy Conversion (WEC) system based on the SCI-Generator. The objective is to control both the generator and the grid side converters in order to operate the system and to ensure the connection with the power grid. The first converter is used to control the SCI-Generator speed and field to extract the available maximum power from the wind turbine by using a Maximum Power Point Tracking (MPPT) technique and, also, to ensure that the extracted power does not exceed its rated value in case of strong wind speeds; in this case a pitch actuator system is used to control the blades pitch angle of the wind turbine. The second converter is used to control the active and reactive powers injected into the utility grid as well as to regulate the DC-Link Voltage. This control takes into account the rejection of internal disturbances as the variation of electrical parameters (the resistance, the inductance…) and the external disturbances as voltage dips and frequency droops in the main grid. To test and validate the performances of the proposed controller, a series of simulations were developed under MATLAB/Simulink environment, and the results have demonstrated the effectiveness of the proposed control under different case of simulations.

“…Among the most used techniques to control the grid-side converter, we can find the voltage oriented control (VOC) or the direct power control (DPC) techniques. However, as described in [3,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], the VOC is considered to be more efficient due to lower energy losses and lower current distortion compared to direct power control (DPC). Hence, v gd � 0 and v gq � v g .…”

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’ 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.

Summary Low voltage ride‐through is considered as one of the key technologies for the operation of grid‐connected photovoltaic power generation systems. At present, the most used control methods are based mainly on PI controllers, and their robustness results are still unsatisfactory. In contrast, this article introduces a new robust control strategy that uses the compensation effect of “total disturbance” before affecting the system; this control strategy is called Active Disturbance Rejection Control (ADRC) method. In addition, most of the controllers use the standard SRF PLL to achieve the phase lock and grid synchronization. However, when the grid voltage is distorted or other unbalanced, it is necessary to use the positive sequence voltage component of the fundamental wave as a reference, but the component of the negative sequence cannot be effectively filtered because of its narrow bandwidth, and then, accurate phase lock cannot be achieved, which may cause a failure. In this purpose, a Double Second Order Generalized Integrator based Frequency Locked Loop (DSOGI‐FLL) is proposed and used to improve the system operating performance and non‐off‐line capability. In order to confirm the robustness of the proposed control strategies, a multiple simulations tests were done by utilizing the Matlab/Simulink software. The results have demonstrated the superiority of the proposed methods and their robustness to symmetrical and unsymmetrical faults.
