“…If Ωt is the rotor speed, the velocity specific ratio λ is defined as : The six coefficients c1.c6 depend on the turbine studied as show in Table 1. In the case of the E-40 turbine, proposed by the German manufacturer ENERCON, these coefficients are [12][13]. Figure 4 shows the variations of the power coefficient Cp as a function of the ratio specific velocity λ, parameterized as a function of the setting angle β.…”

In this work, we presents a control scheme of the interface of a grid connected Variable Speed Wind Energy Generation System based on Doubly Fed Induction Generator (DFIG). The vectorial strategy for oriented stator flux GADA has been developed To extract the maximum power MPPT from the wind turbine. It uses a second order sliding mode controller and Kalman observer, using the super twisting algorithm. The simulation describes the effectiveness of the control strategy adopted.For A step and random profiles of the wind speed, reveals better tracking and perfect convergence of electromagnetic torque and concellation of reactive power to the stator. This control limits the mechanical stress on the tansmission shaft, improves the quality of the currents generated on the grid and optimizes the efficiency of the conversion chain.

In this document are revised different control techniques applied to distributed generation systems, including control of active-reactive power, load-frequency control and the identification and control of island mode operation of the generation units, which are the main themes identified. The different control strategies identified are PID, robust, predictive and fuzzy, with applications in the aforementioned subjects. Particularly, applications for the interconnection of generation units and the control of the electric power conversion system DC-AC (inverter) are observed.

This paper proposes an adaptive gain second-order sliding mode control strategy to track optimal electromagnetic torque and regulate reactive power of doubly fed wind turbine system. Firstly, wind turbine aerodynamic characteristics and doubly fed induction generator (DFIG) modeling are presented. Then, electromagnetic torque error and reactive power error are chosen as sliding variables, and fixed gain super-twisting sliding mode control scheme is designed. Considering that uncertainty upper bound is unknown and is hard to be estimated in actual doubly fed wind turbine system, a gain scheduled law is proposed to compel control parameters variation according to uncertainty upper bound real-time. Adaptive gain second-order sliding mode rotor voltage control method is constructed in detail and finite time stability of doubly fed wind turbine control system is strictly proved. The superiority and robustness of the proposed control scheme are finally evaluated on a 1.5 MW DFIG wind turbine system.
