“…Wind electric generation is one of the best alternative electric energy sources because of its economic benefits and usefulness for power systems in diverse areas . For a variable speed wind turbine (WT), there are many reasons to use a DFIG, such as noise reduction, effort reductions on the WT shaft, reduced cost inverters, and the possibility for stator active and reactive powers control .…”

“…The DFIG rotor is coupled to the grid via power electronic converters (rectifier, filter, and inverter), while the DFIG stator is linked directly to the grid; this configuration allows decoupling the grid frequency from the DFIG rotational speed . In fact, a rectifier can be directly linked to the grid or via the step‐up transformer terminals, which provides a stable DC voltage in the output of grid‐side converter (GSC) . The DC‐link voltage is used as the voltage source for rotor‐side converter (RSC), which is directly coupled to the rotor winding terminals …”

Summary Wind energy has many advantages because it does not pollute and is an endless source of energy. The most used electric machines for horizontal axis wind turbine is the doubly fed induction generator (DFIG). In this paper, the authors propose a real‐time field‐oriented control based on sliding mode (FOC‐SM) for a DFIG prototype connected to the grid via a 3‐phase transmission line. To track the desired DC voltage reference at the output of the DC link and to maintain constant the electric power factor at the step‐up transformer terminals controlled by grid‐side converter, a vector‐oriented control combined with sliding mode is introduced; and to force independently the rotor currents to track a specified reference defined from the required stator active and reactive powers, controlled by rotor‐side converter, an FOC‐SM control scheme is proposed. The DFIG rotor is coupled to the grid via a back to back power electronic converter, whereas the stator is directly linked to the grid. The proposed control scheme is experimentally validated on a 1/4 HP DFIG prototype and tested under constant and variable wind speed, maximum power extraction, and fault grid conditions. The real‐time results show that the proposed controllers achieve a high performance under ideal and no‐ideal grid conditions. Moreover, the proposed scheme is robust in presence of uncertainties, which usually exist in the real system.

“…Investigations to determine the best nonlinear control technique that can be used to improve the performance of DFIG-based WEC systems are still ongoing [29]. The control of both the grid side converter (GSC) and the rotor side converter (RCS) in one control loop was reported in [30].…”

Feedback Linearization Controller for a Wind Energy Power System

This paper deals with the control of a doubly-fed induction generator (DFIG)-based variable speed wind turbine power system. A system of eight ordinary differential equations is used to model the wind energy conversion system. The generator has a wound rotor type with back-to-back three-phase power converter bridges between its rotor and the grid; it is modeled using the direct-quadrature rotating reference frame with aligned stator flux. An input-state feedback linearization controller is proposed for the wind energy power system. The controller guarantees that the states of the system track the desired states. Simulation results are presented to validate the proposed control scheme. Moreover, further simulation results are shown to investigate the robustness of the proposed control scheme to changes in some of the parameters of the system.

“…The converter's capacity is relatively small and largely influenced by the status of the grid. Therefore, higher requirements are desired if DFIGs are to be constructed on a large scale and operated in grid-connected mode [6][7][8][9]. Though the PI regulator based vector control is commonly used and can ensure stable operation of DFIGs within certain range, it is not intrinsically robust, and it can be rather difficult to realize the overall stability of the system.…”

According to the theory of passivity-based control (PBC), this paper establishes a port-controlled Hamiltonian system with dissipation (PCHD) model for a doubly fed induction generator (DFIG) system under unbalanced grid voltage conditions and proposes a method of interconnection and damping assignment passivity-based control (IDA-PBC) of the system under such conditions. By using this method, the rotor-side converter and grid-side converter can be controlled simultaneously in order to improve fault ride-through capability of the DFIG system. Simulation results indicate that this IDA-PBC strategy effectively suppresses fluctuations of output current and power in the DFIG system during unbalanced grid voltage sag/swell, enhances dynamic performance, and improves the robustness of the system.
