This article presents a sliding mode control (SMC) with artificial neural network (ANN) regulator for the doubly fed induction generator (DFIG) using two-level neural pulse width modulation (NPWM) technique. The proposed control scheme of the DFIG-based wind turbine system (WTS) combines the advantages of SMC control and ANN regulator. The reaching conditions, robustness and stability of the sy...

This paper presents a vector control direct (FOC) of double fed induction generator intended to control the generated stator powers. This device is intended to be implemented in a variable-speed wind-energy conversion system connected to the grid. In order to control the active and reactive power exchanged between the machine stator and the grid, the rotor is fed by a bi-directional converter. ...

As the grid codes of wind turbines note, doubly fed induction generator (DFIG)-based energy conversion system (WECS) should maintain uninterrupted operation during certain voltage faults. To meet codes, a novel configuration DFIG-based WECS is proposed in which superconducting magnetic storage (SMES) and series transformer are incorporated. The control strategies redesigned to smooth output pow...

This paper presents the simulation results of a grid-connected wind driven doubly fed induction machine (DFIM) together with some real machine performance results. The modeling of the machine considers operating conditions below and above synchronous speed, which are actually achieved by means of a double-sided PWM converter joining the machine rotor to the grid. In order to decouple the active...

In this paper, particle swarm optimization (PSO) is proposed to generate an On-Off Controller. On-Off Control scheme based maximum power point tracking is proposed to control the rotor side converter of wind turbine equipped with doubly fed induction generator connected to the grid with battery storage. The Grid Side Converter (GSC) is controlled in such a way to guarantee a smooth DC voltage a...

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, ...

The paper presents an optimum design procedure for the controller used in the frequency converter of a variable speed wind turbine (VSWT) driven doubly fed asynchronous generator (DFAG) by using Proportional-Integral (PI) controller. The cascaded control is frequently used in the control of the frequency converter using the proportional PI controllers. The setting of the parameters of the PI co...

In this paper, a generalized predictive control scheme for wind energy conversion systems that consists of turbine and doubly-fed induction generator is proposed. The design created by using the maximum power point tracking theory to maximize extracted power, even when uncertain or speed varies abruptly. suggested controller guarantees compliance with current constraints applying them in regula...
