  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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) ...

  • Feasibility Study of Wind Power in India - 2014

    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 ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Exergy analysis of a wind turbine

    The present paper deals with a developed and improved approach for exergy analysis of the wind. Based on this model, a typical wind turbine model (Bergey Excel-S) is assumed to be installed in two cities in Iran. The results show that, with regard to the annual average wind data, if the wind turbine is installed in Tehran, by varying the cut in, rated and furling speeds from 3.1, 13.8 and 15.6 ...

  • Wind Surpasses Nuclear in China

    Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive growth of 80 percent per year. ...

  • Regional electricity price differences due to intermittent wind power in Germany: impact of extended transmission and storage capacities

    A fast growth of installed wind power capacity has been experienced in several European countries. In Germany, notably high wind power capacities are planned in the North. If the existing transmission capacities between individual regions become insufficient, the electricity prices will differ considerably and the system operation can become unstable. It is supposed that the extension of ...
