  • Lightning protection optimization for large wind turbines

    Electro-magnetic fields adjacent to the lightning current path in wind turbine generators are analyzed. The method of moments is used to analytically describe the transient distributed electro-magnetic field caused by a lightning strike. A simulation tool using the method of moments is presented. The electromagnetic field distribution during a lightning strike in a wind turbine hub is analyzed in ...


  • Reducing avian collisions with wind turbines

    Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical ...

  • Optimal Power Flow under Variable Wind Generation

    In this paper Optimal Power Flow (OPF) problem is solved for a power system, which includes wind power as an additional generation input under variable load conditions. The fixed-speed Wind Turbine Generator (WTG) option is considered in this study: simulations have been performed for various sizes of wind farm attached to the IEEE 30-bus systems using the DIgSILENT Power Factory simulation ...

  • 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 ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • 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 ...

  • Pumped hydro storage softens blow of wind imbalance penalties

    Quarry Battery is developer of the £160 million ($249.2 million) Glyn Rhonwy pumped hydro facility in Wales which will be the UK’s first grid-scale electricity storage facility for decades. The facility will produce nearly 50 MW of electricity using pumped hydro technology. As more fossil fuel-fired generation is taken offline and wind capacity grows, grid operators will ask wind ...

  • Official market forecast for South Africa’s Wind Energy Industry released

    2015’s official Wind Energy Forecast for the South African market was released today detailing the key market trends in 2015 for wind energy in in the country.  Leading experts from Vestas, Siemens, Barclays, and Green Cape discussed key questions facing this year’s wind energy market inside the 8 page report.  This January, experts ...

  • Reducing costs of emerging renewable energy technologies – an analysis of the dynamic development with wind power as case study

    Renewable energy is considered important to improve environmental performance and the long-term security of energy supply. As most renewable energy technologies are not competitive in conventional power markets, they need public support in order to become so. The purpose of this paper is to discuss and understand the dynamic structure in development of renewable energy technologies in connection ...

  • Performance estimation of HAWT blade using NACA airfoils

    Wind energy is one of the developing resources of renewable energy. In order to increase the use of wind energy, development of wind turbine blade with higher power coefficient plays a vital role. The work being presented here is to give new design of blade for VESTAS V82–1.65MW (HAWT). In this work, NACA airfoils are used for the determination of aerodynamic performance characteristics of ...

  • Spares storage can halve downtimes, cut purchase prices

    The advanced purchase and storage of spare-parts can halve the number of downtime days for a typical wind farm and costs can be controlled by buying in bulk and sourcing from a wider market base including refurbished products, Derck van Ommeren, head of sales for the Dutch spares provider WindTurbineSpareParts.com, told Wind Energy Update. It may not be cost effective to keep a full set of spare ...

  • Monopiles to remain Dominant Offshore Foundation in Europe: Consultant

    Monopiles will be Europe’s dominant offshore wind foundation for the next five years despite increasing turbine capacity, Tim Fischer, Head of Wind at German consultancy Ramboll, said. Monopile projects have dominated the offshore wind market but windfarms are moving towards larger turbines requiring larger foundations. While many proponents are promoting ...

  • Is marine energy about to go mainstream?

    Why the costs of wave and tidal power could soon plummet - viewpoint from Dr Stephen Wyatt, Head of Technology Acceleration, Carbon Trust As the marine industry gathers in London for its annual get together one thing is clear; the sector is growing up fast.  So fast that it looks like it will soon be defying its critics and getting its feet seriously wet after many years of ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...
