  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • On methodology for modelling wind power impact on power systems

    There is a continuous discussion going on concerning the integration cost of wind power. The integration cost can, for example, be defined as the extra costs in the rest of the system when wind power is introduced, compared with the situation without wind power. The result of the studies depends on both parameters and the method used. The aim of this paper is to structure the methods in order to ...

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • 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 ...

  • Study on environmental impact model of grid-connected wind power generation

    As a clean and renewable energy source, wind power is independent from the traditional external energy change, which makes it one of the most promising ways of clean energy generation. It is well known that wind power has obvious energy saving efficiency. But for long-term consideration, wind power generation still has certain impacts on human life. Therefore, standing in the point of the ...

    This is an Investor Series report which provides the information on: Wind Turbine Design and Characteristics Permits and Licensing Site Selection Criteria Economics and Financial Model Operations and Maintenance Modern Trends in Wind Farms Case Study in Wind Sector Grid Connection ...


  • Estimation of capacity credit for wind power in Libya

    This paper presents the results of a study that evaluated the wind potential at the central region of the Libyan coast and estimated the capacity credit of wind power in the national network. Several sites were investigated to choose the most suitable sites for wind farm establishment. Different sizes of Wind Energy Converter Systems (WECSs) were selected to estimate the wind potential. The sizes ...

  • China Wind Power 2010 - an enlightening exhibition

    China Wind Power is the largest wind energy event in Asia, where some 500 exhibitors displayed their products this October – a 25% increase on 2009. The event was hosted by the major organisations in the wind energy industry in China: Global Wind Energy Council (GWEC) China Renewable Energy Industries Association (CREIA) Chinese Wind Energy Association (CWEA) ...

  • Wind modelling based on wind input data conditions using Weibull distribution

    Weibull distribution can be used to model the wind speed distribution at a particular site and hence, it can help in wind resource assessment (WRA) of a site. By calculating the shape (k) and scale (c) parameters for Weibull distribution, the wind speed frequency curve for a site can be made. Once this wind speed distribution for site is determined, it can be convolved with the power curve for a ...

  • Dynamic validated model of a DFIG wind turbine

    This paper presents the development and qualitative validation of a doubly-fed induction generator (DFIG) wind turbine model that is represented in terms of behaviour equations of each of the subsystems, mainly the turbine rotor, the drive train, the induction generator, the power converters and associated control systems and a protection system. Simulation results obtained from the models are ...

  • Development of linear models of Static Var Compensators suitable for enhancing performance of power systems including wind farms

    In this work, the design of fixed-gain Proportional?Integral?Derivative (PID) controllers with multiple stage lead-lag compensators are investigated for improving further the dynamic impact of Static Var Compensators (SVCs). The analysis is based on the linearisation of the power system under study and the proper shift of critical eigenvalues, associated with the SVC and electric network, to the ...

  • Design of simulator for modelling of wind turbine and transfer of maximum power using buck-boost converter

    A small wind turbine simulator based on a separately excited DC motor-permanent magnet synchronous generator (PMSG) set has been proposed to evaluate the performance of the small wind turbine model. A DC shunt motor is used to produce varying aerodynamic power by varying field current with the help of an IGBT switch. The simulator is an equivalent gearless wind turbine model that fluctuate ...

  • ADMS 5 Buildings Validation Lee Power Plant Wind Tunnel Study

    1 Introduction The Lee Power Plant wind tunnel study1 [1] featured releases from steam boiler stacks with a common height of 64.8 m affected by a building tier with a height of 42.6 m. The world's largest fluid modelling study chamber at Monash University in Australia was used for these experiments (see plan view in Figure 1). Stable meteorological conditions were simulated by ...

  • Using a DFIG–based wind farm for grid node reactive power compensation

    Grid nodes voltages are not allowed to deviate excessively from nominal value. Appropriate measures should be taken to prevent such a deviation. The voltage difference between two nodes is strongly affected by reactive power flow. In contrast to frequency control, node voltage control must be achieved locally. This article investigates the use of a wind farm based on a doubly fed induction ...

  • Maximum power point tracking for wind energy conversion systems based on fuzzy modelling and control

    Wind energy conversion systems (WECS) have merits as environmentally friendly and renewable sources of energy. Because of its stochastic variations, power management concepts are essential to extract as much power as possible from the wind when it becomes available. The purpose of this paper is to present a TSK fuzzy model, which represents the turbine characteristic for maximum power point ...
