This paper deals with the problems of intermittency of primary source of wind energy and the external disturbances. Subsequently, a power management and a robust control of a standalone energy production unit are presented. This production unit comprising a variable speed wind turbine coupled to a Permanent Magnet Synchronous Generator (PMSG) and a module of Super-Capacitors (SC) that is considered as an Energy Storage System (ESS). This unit feeds a three-phase load by means of an inverter and an RLC filter. In order to assure a control strategy which has a very good performance despite the high nonlinearity of wind systems and an intermittence form of wind power, a second-order sliding mode control based on a super-twisting algorithm is applied to a PMSG. Then, a power management strategy is applied to the SC using a buck-boost converter according to load instructions and wind speed fluctuations. The response of the power algorithm enables to ensure the power flow exchange between the production unit and the power consumers and to protect the ESS against overcharge and excess discharge to ensure safe operation. Finally, using PI controllers, the inverter adjusts the capacitors voltages and currents at the output of the RLC filter with the nominal frequency and voltage. The simulation results show the robustness of the implanted control strategy.

“…SMC has been successfully implemented in DFIG control and tested under unbalanced conditions and harmonics [11,[15][16][17][18]. However, the proposals given in [16,17] require modulation, and the tested faults are moderate since these do not represent a brusque variation in the stator voltage. The SMC presented in [15][16][17][18] works under unbalanced conditions but implementation of the SMC regarding the commutation of the power electronics is not discussed.…”

Doubly-fed induction generator (DFIG) is the most implemented electric machine in wind energy conversion systems (WECSs) due to reduced size converter, active and reactive power control, and economic factors. However, the power electronic stage needs an accurate controller that allows to follow the stator power regulation despite the presence of disturbances. On the other hand, sliding-mode control (SMC) offers a fast-dynamic response and provides insensitivity to matched and bounded disturbance/ uncertainties, and its natural discontinuous control signals can be used for direct switching of power electronic devices. Switching frequency must be maintained inside acceptable values to avoid exceeding the maximum admissible switching frequency of semiconductors. The contribution of this chapter is a stator-flux-oriented SMC with a hysteresis band that limits the switching frequency of power electronic devices to a set value. Furthermore, the proposed SMCs ensure robustness against bounded lowvoltage grid faults. Unlike other nonmodulated techniques like direct torque control (DTC), there is no necessity of modifying the controller structure for withstanding lowdepth voltage dips. The controller injects negative sequence voltage/currents to compensate the unbalanced conditions. The advantages of the proposed SMC control are validated via simulations.

“…This kind of generator has gained more interest due to its advantages over other generators, such as full variable speed operation, power control capability, robustness, and reduced inverter costs [2][3][4]. However, this generator can be affected by different kinds of faults, such as open-phase failure, short circuits, current sensor faults, voltage dips, and speed sensor faults [5][6][7]. These faults can be caused by sensors, actuators, or the system itself [8].…”

Fault-tolerant controller (FTC) designs for doubly fed induction generators (DFIGs) with actuator faults have recently gained considerable attention due to their important role in maintaining the safety and reliability of DFIG-based wind turbines via configured redundancy. The objective of this paper is to propose a novel active fault-tolerant tracking control strategy for a DFIG subject to actuator faults. The proposed strategy consists of first designing a proportional integral observer (PIO) for simultaneous system states and fault estimation and then secondly the FTC, which depends on the estimated states and faults. The objective of such a controller is to drive the state of the system to track a reference state generated by a reference fault-free model (nominal system). In addition, the main results for stability are demonstrated through a quadratic Lyapunov function, formulated in terms of linear matrix inequalities (LMIs) in order to guarantee the stability of the whole closed-loop system and to reduce the actuator fault effects with noise attenuation.Furthermore, the gain matrices of the FTC and the PIO are computed by solving a set of LMIs using the YALMIP toolbox with the SeDuMi solver. Finally, the simulation results under constant and time-varying actuator faults are provided to show the effectiveness of the developed FTC scheme.
