  • European Power Markets in Transition

    With European energy markets in transition, all market participants now face a number of potentially tricky challenges. A combination of EU initiatives, increasingly invasive regulations and a backdrop of falling and less volatile commodity prices, have precipitated an era of change and uncertainty in which there are fewer trading opportunities and profits are harder to come by. Analysis ...

  • 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 ...

  • 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 ...

  • Many hamsters: how the EU can enable private firms to provide renewable energy

    This paper investigates the energy investment needs of the European Union (EU), including renewable energy. Europe currently has little or no economic growth, and interest rates are expected to rise. Given the state of many EU countries' economies, this is a good time to encourage investment because - according to Keynesian economics - extra spending can stimulate economic activity. The current ...

  • 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 ...

  • Smart Grid Deployment Critical for Clean Energy Future

    A new report from the International Energy Agency (IEA) says the widespread deployment of “smart grids” – networks that monitor and manage the transport of electricity from all generation sources to meet the varying electricity demands of end users – is crucial to achieving a more secure and sustainable energy future. With current trends in the supply and use of energy ...

  • Large-scale hydropower system optimization using dynamic programming and object-oriented programming: the case of the Northeast China Power Grid

    This paper examines long-term optimal operation using dynamic programming for a large hydropower system of 10 reservoirs in Northeast China. Besides considering flow and hydraulic head, the optimization explicitly includes time-varying electricity market prices to maximize benefit. Two techniques are used to reduce the ‘curse of dimensionality’ of dynamic programming with many ...

  • Market power monitoring under open access system

    In this paper, an engineering procedure is proposed for complete market power monitoring under open access system. Market power monitoring of any given system or network is done by using market power assessment and market power indices. For any given network, market power assessment is to identify which generation company (GENCO) raised their prices when the demand in the concerned area is ...

  • 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 ...

  • White Paper: MicroGrids Contribution to the Smart Grid

    It is now becoming clear that the fundamental architecture of today’s electricity grid, based on the idea of a top down radial transmission system with unidirectional energy flows from large centralized power plants, is not the most appropriate to meet the needs of the low carbon economy. Micro-generation and micro-grids need to be incorporated into the electrical supply system because ...

  • Spectral analysis of a real power network

    We present a spectral analysis of a significant part of the Italian bulk power system. Spectral analysis applied to graphs is not a new tool, but analyses of the real world, especially of technological networks, currently are lacking. We show the spectral pattern of a high voltage power network, calculate the ratio between the smallest and largest non–zero Laplacian eigenvalue to check its ...

  • 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 ...

  • Is Eaton`s Purchase of Cooper a Bellwether for the Smart Grid Sector?

    Most of the clean technology industry depends heavily on the political climates and the availability of subsidies or incentives to generate demand. As we’ve seen with the solar and wind industries, political squabbles and poor business planning create a logjam in the installed capacity increases of wind power and the rapid technological innovation of solar technologies. While solar and wind ...

  • How do we create an ethical grid?

    So much of what’s discussed in offices these days – and forever really – focuses on this: What’s best for the company? How do we increase profits? That’s totally understandable, given that a primary responsibility of any for-profit enterprise is to benefit its owners and investors. Still, as individuals, and I would argue, as part of the capitalist system, we have ...
