“…Multiple versions of wind turbine model have recently been designed and can be obtained throughout the literary works [2,18,22,23]. Due to the fact that the electric response of the system is our bottom line, the observed model in Figure 1 is therfore presumed: The self-excited induction generator design established in this paper is expressed in  reference frame as preseented in Figure 2.…”

“…However, the terminal voltage stability of the Induction Generator (IG) cannot be guaranteed with only a shunt connection to a fixed capacitor bank. Thus, several voltage regulation schemes have been proposed by researchers using mechanically switched capacitors, synchronous condensers and Flexible AC transmission (FACT) devices such as the Static Var Compensator (SVC) or more recently the Static Synchronous Compensator (STATCOM) [1,2].…”

<span lang="EN-US">In the literature, it is well known that reactive power management is the greatest challenge in wind turbine based on a three-phase self-excited induction generator. Any variation of wind speed or load causes a variation on the needed reactive power and thus a voltage fluctuation. Flexible AC transmission device such as STATCOM become then a necessity to prevent voltage instability and hence voltage collapse at the point of common coupling. This paper proposes so a new control strategy for voltage regulation of an asynchronous wind turbine based on a combination of a single input fuzzy logic regulator and a sliding mode controller. Compared to the classical control strategy with PI regulators, the performance of the proposed compensator has been significantly improved when it is controlled by the new approach and the system have shown more robustness and stability regarding external disturbances. The present document traits so the modelling of the power system, the simulation results and the controller’s scheme and design.</span>

The distribution static compensator (D-STATCOM) is a power quality compensator, which can be utilized for improving the power quality of the distribution power grid by managing the flow of reactive power and unbalanced caused by variable and unbalanced loads. This paper develops the concept of regulating the D-STATCOM scheme to improve the dynamic proficiency of the power distribution network during electrical network defects, such as voltage drops and voltage swells. Furthermore, the methodology adopted in this research paper is established to utilize the sliding mode control (SMC) for the proper working of D-STATCOM. The simulation of the suggested SMC methodology has been carried out by employing the MATALB/Simulink software and compared the results with traditional proportional integrator regulator. The results show that the suggested approach controlling the D-STATCOM achieves sinusoidal and symmetrical grid current with less harmonics; moreover, it can efficiently eliminate the oscillations produced in active and reactive power. Hence, the proposed strategy is helpful in mitigating the voltage flicker and improving the overall efficiency of the distribution grid.

“…Thanks to these research activities, the latest generations of wind turbines operate at variable speed to extract the maximum electrical power depending on the wind speed [1][2][3][4][5][6][7][8]. The development of power electronics control techniques has introduced intelligent controls [9][10][11][12][13][14]. In the case of the use of wind turbines dedicated to isolated sites, various electrical machines are used such as the DC machine, synchronous machine and asynchronous machine.…”

<p>This paper focuses on the study of the asynchronous generator self-excited during operation in isolated mode. It concerns the analysis of a robust control of the asynchronous machine in order to improve the quality of the electrical energy produced in different environmental circumstances, and to promote the use of renewable energies in rural areas to improve education, the supply of drinking water, livestock and agriculture, access to information and communication. The present work concerns the description and modeling of the various mechanical parts of the wind turbine. It also tackles the steady-state and transient modeling of the asynchronous generator under self-excitation conditions. The practical results and the simulation ones have shown the influence of the self-excitation capacity on the output quantities of the wind system (voltage, current and torque) in vacuum and under charge (resistive and inductive). In the case where the asynchronous wind turbine is connected to a network, it imposes amplitude, waveform and frequency. But in the case of isolated sites, the asynchronous machine has a low power factor, what means it requires reactive energy. To correct this irregularity, we can improve the power factor by using variable capacitors. The excitation current (reactive power) must be permanently supplied according to the load connected. This requires an intelligent system that regulates the electrical energy produced. </p>
