  • Wind energy and system security – the grid connection moratorium in Ireland

    This examines the interaction between technical challenges and policy choices that are made regarding wind power, and uses the grid connection moratorium in Ireland as a case study. While total installed wind capacity in Ireland is low compared with Germany, Spain and Denmark, wind power penetration is higher in the Irish system than in either the British, UCTE or NORDEL systems. In December 2003 ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Planning of the grid integration of wind energy in Germany onshore and offshore up to the year 2020

    The ongoing penetration of large amounts of wind power capacities in Germany has strong impacts on the necessary promotion volumes (direct costs of Renewable Energy Source (RES) promotion) but also on necessary grid extensions, the future need for regulating and reserve power capacities, the thermal power plant system and the electricity price for end-consumers (indirect effects). On behalf of ...

  • Harmonic and interharmonic distortion analysis in the grid-connected wind electric generator

    The operation of wind turbines has an impact on the power quality at the connected electric network. The integration of wind electric generators with the power grid becomes a headache for power engineers in several aspects. Harmonic distortion is one of the most important phenomena which affect the grid performance. This paper provides an in-depth discussion on harmonic and interharmonic ...

  • Wind Energy Market in China 2014

    This latest market research report titled Wind Energy Market in China 2014 analyses how the renewable energy sector is gaining importance in China and how wind energy has become an indispensable part of this sector. With the gap in demand and supply of energy increasing at a steady pace, it has become necessary to look beyond conventional sources for generating energy. This has led to a shift in ...


  • Wind energy today and in the 21st century

    Wind energy is the most promising of the new renewable sources of energy. By the end of 1998, the global installed capacity of modern grid connected wind turbines was some 10,000 MW, and the growth rates of installations worldwide are 30%-40% annually. The cost of wind energy was reduced by 30% between 1991 and 1997 and the cost reduction is foreseen to continue. This article reviews the reasons ...

  • Smart Grid: The game

    In his best seller “Outliers,” Malcolm Gladwell shows that it is not equipment failure or storms that typically cause planes to crash, but wrong decision-making. Much the same can be said for the power grid crash that took down a large swath of the Northeast in August 2003. The emerging smart grid is supposed to make our power system more reliable. The bad news is that it also will add complexity ...

  • CSP Thermal Energy Storage vital for utilities and grid operators

    The modern age of CSP can arguably be traced back to the 354MW Solar Energy Generating Systems (SEGS) in the Mojave desert, which now make up the oldest operating plant in the world, as well as one of the largest. However, recent developments in the industry will see SEGS eclipsed by 5 projects that are scheduled to come online in 2013-14, with a combined total of 1312MW. The five plants in ...

  • Smart grid: How big is big?

    A Cisco executive attracted some eye rolling after commenting that smart grid could be “even bigger than the Internet.” But the statement isn’t farfetched when you think about what smart grid encompasses: a convergence of three industry giants: information technology, telecommunications and the electric grid, the world’s biggest machine. A report this week by Greentech Media made clear just how ...

  • Wind Energy Technologies: Technology, Market and Costs

    Technology Overview   These large wind turbines turn Midwestern wind into utility electricity. Wind turbines convert the power in the wind into electricity. By extracting the kinetic energy in the wind, wind turbines generate mechanical power.

  • What the heck is a smart grid anyway?

    You know the old adage, ‘Never talk about politics or religion in polite company’? I’m beginning to think we need to add a third restraint, one against debate over the meaning of smart grid.Okay, it’s not exactly a dinnertime topic. But I’ve discovered in gatherings of energy nerds (I’m one), discussion can become fairly heated over what constitutes “smart grid.”On the one side are the ...

  • Stabilisation of grid connected wind farms using doubly–fed induction generators with FACTS controllers

    The impact of the wind generation on the power systems is no longer negligible if high penetration levels are going to be achieved. It is very important to boost the transfer capability of the transmission system while improving the utilisation of transmission assets to accommodate high penetration of wind power on the network.
