In this paper, we present a nonlinear robust control of active and reactive power by the use the PI regulators control (FOC) a Double-Fed Asynchronous Generator (DFIG) system incorporated in a windturbine. The power transfer between the stator and the network grid is carried out by acting on the rotor via a bidirectional signal converter. Initially, a control strategy of the MPPT-DFIG is presen...

This paper discuss the configuration, operation and power flow control strategies of a doubly fed induction generator (DFIG) with back-to-back PWM converter for variable speed wind turbines. The mathematical model of the DFIG is taken as appropriate d-q reference frame and their performances are in terms of stator currents references tracking. In order to control the power flow of the network, ...

In this paper, a grid connected wind power generation scheme using a doubly fed induction generator ( DFIG) is studied. The aims of this paper are: The modelling and simulation of the operating in two quadrants (torque-speed ) of a DFIG, the analysis employs a stator flux vector control algorithm to control rotor current, the system enables optimal speed tracking for maximum energy capture from...

The impact of fixed speed squirrel cage type as well as variable speed doubly fed induction generators (DFIG) on dynamic performance of a multimachine power system has been investigated. Detailed models of the various components have been presented and the integration of asynchronous and synchronous generators has been carried out through a rotor angle based transform. Simulation studies carrie...

In the recent years, many wind turbine generation systems (WTGS) have been installed in many countries. However the electric power obtained from wind generators is not constant due to wind speed variations. The generated electric power and the loss in WTGS change corresponding to the wind speed variations, and consequently the efficiency and the capacity factor of the system also change. In thi...

The wind turbine based on the doubly-fed induction generator (DFIG) plays an increasingly important role in power generation. This is thanks to the benefits of these generators compared to other machines. In this paper, we present a new control strategy that limits variations and the transient overshoots in the DC bus voltage, which cause problems and sometimes leads to destruction of converter...

wind energy today, has attracted widespread interest from among a variety of sources of renewable energy in the world. owing to the increasing demand for production of electrical energy for electricity networks by using wind power, it is essential that wind power plants are actively incorporated in the network’s performance using an appropriate control system. in general, these wind power plant...

This paper proposes a parallel-resonance bridge type fault current limiter (PRBFCL) to augment the transient stability of a hybrid power system consisting of a photovoltaic (PV) power generation source, a doubly-fed induction generator (DFIG)-based wind energy system, and a synchronous generator (SG). The PRBFCL is designed such a way that it can provide sufficient damping characteristics to th...

In this paper, a wind power system based on a doubly-fed induction generator (DFIG) is modeled and simulated. To guarantee high-performance control of the powers injected into the grid by the wind turbine, five intelligent super-twisting sliding mode controllers (STSMC) are used to eliminate the active power and current ripples of the DFIG. The STSMC controller is a high-order sliding mode cont...

Because wind generators (WGs) in a wind power plant (WPP) produce different active powers due to wake effects, the reactive power capability of each WG is different. This paper proposes a hierarchical voltage control scheme for a WPP that uses a WPP controller and WG controller. In the proposed scheme, the WPP controller determines a voltage error signal by using a PI controller and sends it to...
