  • Vector control of current regulated inverter connected to grid for wind energy applications

    Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. The vector control of an inverter connected to the grid is presented. The proposed control technique implies a hysteresis current controller in the inner loop. The complete control system has been developed, analysed, and validated by simulation ...

  • Robust vector control strategy for variable speed wind turbines

    The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a robust control for variable speed wind power generation that incorporates a doubly feed induction generator is described. The electrical systems incorporate a wound rotor induction machine with back–to–back three phase power converter bridges between its rotor and ...

  • Wind power smoothing using rotor inertia aimed at reducing grid susceptibility

    Due to wind speed variations, the output power of wind turbines fluctuates. These power fluctuations make the wind power undispatchable. Furthermore, they can cause frequency deviations and power outage particularly when wind power penetration is significant. This paper presents a novel control method to mitigate the power fluctuations using the rotor inertia as an energy storage component. ...

  • Modelling and control of a variable speed wind turbine driving doubly fed induction generator using three–level PWM converter

    The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two–pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the utilisation of three levels voltage ...

  • A combined electro-mechanical control technique for dynamic voltage regulation of a stand-alone wind turbine generator

    This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load voltage regulation. Speed regulation is achieved by adjusting the pitch angle of the turbine blades. ...

  • Sub and super-synchronous wind turbine-doubly fed induction generator system implemented as an active power filter

    This paper deals with a wind energy conversion system (WECS), based on a doubly fed induction generator (DFIG) and an electromechanical active power filter (APF). The objective is to respond simultaneously to electric energy requirement and power quality concerns. The proposed WECS is able not only to track the maximum power point of the wind energy but also to dampen harmonic currents from the ...

  • Optimal control of matrix converter based WECS for performance and stability enhancement at low wind speeds

    In this paper, optimal control of new wind energy conversion scheme where four-leg improved matrix converter (MC) is used for performance and stability enhancement, particularly for sites where most of the time low wind speeds prevails, has been explained. The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal ...

  • Community Wind Power for Renewable Income

    CONSIDERING its incredible history and environmental benefits, wind power is one of the most underutilized sources of renewable energy. Stretching back as early as 200 BC, communities have been harvesting the wind for power. However, the scale and popularity of wind power is only now starting to reach critical mass as concerns of climate change rise and energy usage continues to soar. While ...

  • Ontario`s Wind Power Sector at a Crossroads

    Despite having Canada's largest population and being home to an energy-intensive manufacturing sector, Ontario was slow to adopt wind power. As recently as 2006, only 10 turbines were spinning in the province. However, the province is currently home to more than 1,750 MW of wind power and plans are in place for this figure to increase to 7,500 MW by 2018. The Policy Environment ...

  • Why the fossil-fuelled reactor fleet in France will not be affected by an evolution of the wind power capacity

    Today's power electronics can confer high-performance adjustment capabilities on any technological object, including the frequency-power and voltage tuning of modern, synchronous-type wind turbines. However, this will not enable such devices to steadily produce electric power from an uncontrolled mechanical energy. Thus they cannot be considered independent generation units: the need to ...
