  • 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 ...

  • Carnedd Wen Wind Farm

    In 2005 npower renewables began investigating the possibility of building one of the largest wind farms in Wales. The farm would consist of 65 turbines standing up to 137 metres high on around 2,600 hectares (ha) of hillside near Llanbrynmair in Powys. To help enhance the impact of the wind farm, npower renewables propose an extensive habitat restoration scheme following clearance of over ...

  • Reactive capability limits of wind farms

    Wind Energy Conversion Systems (WECS) technology can be classified into two main types: fixed speed and variable speed. Fixed speed WECS use an induction generator connected directly to the grid while variable speed WECS use a power converter to connect the generator to the grid. Fixed speed WECS require shunt capacitors for reactive power compensation, while variable speed WECS have reactive ...

  • Powering Renewable Programs: The Utility Perspective

    When considering how to build out a renewable energy portfolio, there are a lot of factors and many points of view to consider. For purposes of this narrative, we will take the point of view of the electric utility itself. Your electricity providers are quite familiar with the concept of a “smart grid.” According to the Department of Energy (DOE), a smart grid “generally refers ...

  • An introduction to reactive power compensation for wind farms

    The paper summarises the refereed contributions of seven articles reviewed for publication in the IJETP – Special Issue on "Reactive compensation for wind farms". The main goal of the special issue is to provide a forum to exchange information on the reactive power compensation requirements for wind farms and introducing possible price mechanisms for today's deregulated power industry. ...

  • Dispatching of wind farms using battery energy storage

    In this paper, a STATCOM interfaced battery energy storage system (BESS) is considered for smoothing intermittent power output of a large wind farm so that it can be dispatched. The main advantage of the system is that it can inject both real power (by charging/discharging the BESS) and the reactive power to the system. The paper investigates the main design issues related to BESS – the control ...

  • Iberdrola to build nine wind farms in Brazil

    Spain’s Iberdrola Renovables and its Brazilian partner, energy company Neoenergia, have received a contract from Brazil’s Agencia Nacional de Energia Electrica (Aneel) to deliver the electric output of nine wind farms—a deal characterized as a major step in allowing the Iberdrola-Neoenergia consortium to move ahead with construction of the facilities. The nine wind ...

  • Sustainability in India through wind: a case study of Muppandal Wind Farm in India

    Sustainable development is closely associated with energy availability. It requires a continuous and efficient energy supply. Therefore renewable energy sources such as wind energy are vital for the Indian economy not only from supply side considerations but also for their environmental and social benefits. The current paper undertakes an empirical study of investments made at the Muppandal Wind ...

  • Proposed offshore wind farm consents process in the UK: some considerations

    The objectives of the study were to define the full details of the consenting process for offshore wind farms in territorial waters (in England and Wales) and to develop guidance aimed primarily at developers outlining the consenting process in its entirety. Conclusions included: the formalisation of available routes to consents for developers; the formalisation of the requirement for a DTI ...

  • Sempra Generation invests in 250 MW Colorado wind farm

    Sempra Generation, a subsidiary of Sempra Energy (San Diego, CA), has made an investment in the Cedar Creek II Wind Farm in Colorado that will make Sempra an equal partner with BP Wind Energy in the development of the project. The Cedar Creek II project is a 250 MW facility located near New Raymer, in the high prairie about 90 miles northeast of Fort Collins. The project’s entire ...

  • Vattenfall to invest over €1 billion in North Sea wind farm

    Swedish power giant Vattenfall announced that it will invest more than €1 billion (about $1.4 billion U.S.) in the DanTysk project, a 280 megawatt (MW) offshore wind farm to be located in North Sea waters between Germany and Denmark. Vattenfall has formed a joint venture with Stadtwerke München GmbH (SWM; Munich, Germany) to develop the DanTysk facility, with Vattenfall holding a 51% ...

  • Maintenance Manager to control operation and maintenance of offshore wind farms

    Maintenance of wind farms is of increasing importance. Especially in remote areas, where logistics and accessibility are restricted, costs of preventive as well as corrective maintenance form a substantial part of the costs of electricity. The importance of a tool that assists in feedback to the design, failure logging, configuration control and maintenance planning is evident. This paper ...

  • 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 ...

  • Renewable, clean energy: the petroleum footprint - wind farms under analysis

    This paper presents a methodology to assess projects for the generation of clean, renewable energy. Such methodology is applied here to estimate the consumption of fossil fuels (referred to as 'oil'), required for the construction, operation and maintenance of a wind farm consisting of 97 turbines of 3 MW each. Results show that such consumption represents a conservative 8–9% of the total energy ...
