  • Experience curves for wind power

    The objective of this study was to improve the understanding of the use of different experience curves in energy analysis. The study was based on the application of experience curves to wind power systems, but the approach is generic and can be used in other energy technologies. In the study, experience curves for wind power were developed, and it has been demonstrated that different types of ...

  • 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 ...

  • Power curve measured and verified – Case Study

    In 2010 RSE SpA (Energy System Research Inc.) within a Program Agreement with the Italian Ministry of Economic Development started a measurement campaign on a Libellula wind plant installed in Tuscany. The campaign lasted 1 ½ years and during this time RSE measured the turbine’s power curve following the requirements of the relevant IEC Standard ...

  • Animation: How Wind Turbines Work

    The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects. By the end of the 19th century, wind energy took on a whole new meaning as engineers ...

  • Finite element structural study of the VGOT wind turbine

    We analyse the implementation of the finite element method to simulate the structural behaviour of the blade-wagons of variable-geometry oval-trajectory (VGOT) Darrieus wind turbines. The key feature of a VGOT machine is that each blade, instead of rotating around a central vertical axis, slides over rails mounted on a wagon formed by a tubular reticulated structure supported by standard train ...

  • Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica

    Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. An ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • 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 ...

  • The economics of wind energy within the generation mix

    With more than 15,000 plants of different capacity ranges, Germany has become the world's No. 1 in generating electricity from wind power, covering around 4% of the electricity requirements at home. This is due on the one hand to the successful promotion by the Renewable Energy Act (EEG) and, on the other hand, to the tax breaks from loss allocation and depreciation. During low-load periods, load ...

  • What’s the Future of R&D in the Wind Industry?

    When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...

  • Verification of wind energy related measurements with a SODAR system

    Abstract Complex terrain and growing wind energy converters (WEC) in wind parks generate increasing interest in determining wind profiles and turbulence besides the general forecast of annual energy production. Increasing hub heights and growing rotor diameters of advanced WEC make SODAR systems a valuable alternative to meteorological towers. SODAR systems provide wind profiles as well as ...

  • An experimental investigation of a solar/wind 4 kW micro generation system and T–1000 1.2 kW PEM fuel cell

    Hybrid system inclusive of renewable energy may be a key component for the solution of global warming, poor air quality, economic dependence, reducing–dwindling reserves of fossil fuels and also carbon tax in Australia. Firstly, this paper describes the experimental setup of wind/solar 4 kW micro generation system, examines the energy produced and various readings of monthly, weekly, daily and ...

  • Want low-cost clean energy? Bank on innovation

    In the United States, there is a heated debate about how much government should support renewable energy innovation. While you won’t find anyone who says they don’t value ‘innovation’, the U.S. federal investment in energy innovation across both fossil and renewable technology is still anemic, ...

  • Continuous, Centralized Monitoring Drives O&M Optimization

    In a survey conducted by Wind Energy Update this year, 80% of wind turbine owners indicated they take either a predictive or preventative approach to maintenance. Furthermore, 77% indicated that they deploy Condition Monitoring Systems (CMS). “If you can leverage data to increase plant performance by even 1%, you are looking at significant impacts to your revenue”, EDF’s ...

  • Create new jobs & cut emissions by investing in renewable energy efficiency

    At a time when major US companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both ...

  • Betting on the Clean Economy

    British Columbia and three Pacific Coast states in the U.S. are counting on clean energy, clean technology and a 'green' economy to grow prosperity and jobs, political leaders told GLOBE 2012's opening plenary. However, increasing global demand for energy will also drive continued fossil energy development including Alberta's oilsands, which provides huge economic benefits, a ...
