  • Off-grid CPV in Latin America

    As company project pipelines for the Latin American market increase CPV’s biggest customer may not be the utility companies of America and Europe but instead industrial and commercial uses may provide the biggest opportunity for CPV in Latin America. London, February 13th 2013 Tecate, Mexico will be the site for the biggest CPV plant in the world. Using a ...

  • Take Your Bedroom Off the Grid

    In recent years there has been a growing interest in renewable energy. The problem is that many people cannot afford to implement a complete renewable energy system all at once. As interest grows and renewable energy equipment prices fall, people will not be ready to take advantage unless the industry and non-profits undertake serious public education. Redwood Alliance, an environmental ...

  • How to reduce Triad energy charges

    The winter Triad season is, once again, upon us and affecting business electricity bills.  It is important for organisations to carefully manage electricity consumption through the Triad season, which can help to dramatically decrease electricity costs. What are 'Triads' and what is the 'Triad' season? ...

  • Solar Energy – Groundbreaking Technology to Simplify Off-the-Grid Living

    The sun is one of the most reliable, free sources of unlimited renewable energy. If it is successfully tapped, it can light up the future of off-the-grid living. One day of the sun’s energy on the earth can power the energy needs of the entire world for more than a year! What Makes Solar Energy So Important? The fact that the sun shines equally on every part of the earth is ...

    Newly minted MIT PhD selected for two-year social entrepreneurship fellowship. Written by Nathan Birnbaum.You can read the original new in MIT NewsMatthew Orosz MEng '03, SM '06, PhD '12 had a lot to be proud of on June 7. Not only was he invested with ...

  • Avoiding the Power Grid with Renewable Energy

    For approximately one hundred years, thriving countries have been dependent on only one form of distributing power; electricity sent over large transmission grids from plants generating electricity, to customers in businesses, homes, and factories.  Generators extract energy from rooftop solar panels, garbage, and sewage, which replace or assist coal, nuclear, and natural gas plants. A ...

  • Ocean Power connects wave energy system to grid

    Ocean Power Technologies, Inc. (Pennington, NJ) announced that it has achieved what it claims to be the first-ever connection of a wave-energy system to the power grid in the United States. Ocean Power’s PB40 Powerbuoy system is now delivering power to the grid at the U.S. Marine Corps Base Hawaii on the island of Oahu. The Powerbuoy unit, which was installed in December 2009 at a ...

  • Knowing power grids and understanding complexity science

    Complex networks theory has been well established as a useful framework for studying and analysing structure, dynamics and evolution of many complex systems. Infrastructural and man–made systems like power grids, gas and water networks and the internet, have been also included in this network framework, albeit sometimes ignoring the huge historical body of knowledge surrounding them. Although ...

  • `Sahara Power` needs pan-European grid operator

    A consortium of leading European – mostly German – companies plans to invest €400 billion in a megaproject to generate solar power in the Sahara desert. “Desertec”, as the project is called, could cover 15 percent of European electricity demand. The problem is, how do you transport this power to Paris and Berlin? ‘It will not work without a pan-European grid operator.’ The figures for the ...

  • As renewable electricity is added to the grid, are power markets misfiring?

    When increasing megawatt-hours of variable solar and wind energy began coursing through the grid, the initial concern was an operational one—could grid reliability be maintained. But it turns out those megawatt-hours are creating market challenges, as well. What needs to be done to right the markets? Travis Kavulla, vice chairman of the Montana Public Service Commission, and Albert Cheung, ...

  • Grid Connection An open letter to those on grid considering pursuing hydro power

    Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our customers are off-grid and there are reasons for this. The question is then more like: ’Can I put in a small hydro system or should I spend ...

  • Cascade failures and distributed generation in power grids

    Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

  • Developing power

    The invention of a long-lasting incandescent light bulb in the 19th century spurred on the second wave of the industrial revolution, illuminating homes, extending leisure time and bringing us to the point today where many millions of people use a whole range of devices from mood lighting to audiovisual media centers, microwave ovens to fast-freeze ice makers, and allergy-reducing vacuum cleaners ...

  • 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. ...

  • What will it take to integrate renewables into the power grid? Ask a bicyclist.

    When it comes to fitting into the current system, bike commuters and electrons have a lot in common. There’s nothing quite like biking down clogged city streets, weaving in and out of traffic. For short distances, it’s faster than driving. It’s liberating. It’s fun. It also makes it painfully clear that most roads ...

  • Improvement of power supply to rural customers through grid-interactive distributed generation

    The integration of Distributed Generation (DG) into distribution grid systems introduces problems in network operation, control and protection. Key issues associated with DG inclusion are voltage or current control, cost-effective operation, protection coordination and network transients. Better understanding of these issues and finding solutions to these problems are important to power ...

  • 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 ...
