“…It includes the simultaneous activation of the PAC and the rotor speed control. To attenuate the steep and large volatile dynamics during turbine switching between low and high wind speed mode, a modified algorithm was proposed in [22]. This algorithm modifies the generator torque control law in the low wind speed mode to reduce the steep change of turbine power and torque.…”

Wind energy is an alternative to meet the growing energy demand. Control of wind turbines should help the reliability and stable operation of the power grid. Furthermore, they should respect the technical requirements according to the grid codes to inject the wind energy into the grid. In this paper, a well-known field-oriented control (FOC) method and a new control method based on the flatness properties (FBC) are presented and compared. These control methods are applied to a wind energy conversion system (WECS), which connects a variable-speed wind turbine (WT) based on a permanent magnet synchronous generator (PMSG) to the grid via a back-to-back converter. The main aim of both control methods is to extract the maximum power from the wind. For this purpose, the mathematical model of each subsystem, i.e., WT, PMSG, and electrical grid, is presented. To evaluate and to compare the dynamic behavior of the high-power wind energy conversion system, it is modeled and the control strategies are developed using SimPowerSystems Toolbox in MATLAB. The simulation results obtained in the time domain show that the FBC performs better at managing the energy in the studied system. Indeed, the proposed FBC is a high bandwidth control method with only one closed-loop control, which leads to a high dynamic performance. Therefore, that strategy can be used to provide ancillary services such as frequency control and spinning reserves according to the grid codes.

Esta investigación propone una metodología de control aplicada a una técnica en Sistemas de Generación de Energía Eólica (WEGS) para el Seguimiento del Punto de Máxima Potencia (MPPT) basada en un observador Fuzzy y complementada con un controlador PI mediante el método de Control Directo de Velocidad (DSC). Este enfoque permite controlar la corriente de referencia del lado del rotor a través de las variaciones de par y potencia eléctrica en un modelo de Generador de Inducción Doblemente Alimentado (DFIG). En consecuencia, la velocidad del generador se controla para obtener una respuesta rápida del máximo Coeficiente de Potencia (). La construcción de esta estrategia comienza con mediciones directas de las variables eléctricas y mecánicas utilizando herramientas computacionales como FAST y Matlab-Simulink para las simulaciones del modelo del aerogenerador. Esta estrategia DSC presenta un rápido desempeño en el seguimiento del considerando la dinámica de un aerogenerador de 1,5MW; esta estrategia ha sido comparada con un controlador PI tradicional mejorando la extracción de la potencia de salida.

In the present work, a control strategy for Maximum Power Point Tracking (MPPT) of a wind turbine based on a Doubly Fed Induction Generator (DFIG) is described. This strategy is developed according to the theory of Di-rect Speed Control (DSC) which includes a state observer. This strategy con-siders the Low Shaft Speed (LSS) as an input and the Iqr reference current as the output. This control mechanism allows monitoring the MPPT; thus, changing the Power coefficient (Cp) to its optimal value during the operation of the wind turbine. The controller, among its main features, is configured to work with the incorporation of different wind inputs; fact that permits evaluating the system response to disturbances and variations. For simulations tests, a 1,5 MW wind turbine has been modeled in Matlab and Fatigue, Aero-dynamics, and Structures and Turbulence FAST software. The strategy has been compared to a PI MPPT controller and has demonstrated improvements in terms of speed and output power extraction.
