  • Googlifying the electric grid

    If you showed Alexander Graham Bell cell phone towers, he’d be stumped. But if you let Thomas Edison tinker with our electricity grid, he’d know just what to do — not because of his genius, but because electric transmission has changed little since Edison’s day. Telephone technology advanced; electricity did not. So says the Department of Energy. ...

  • 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, ...

  • 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 ...

  • 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 ...

  • Agents controlling the electric power infrastructure

    The electric power grid is evolving from a centrally controlled grid with only a handful of regulated monopolies to an open, liberalised electricity market. In addition, more and more small-scale dispersed generators are deployed in distribution nets. This puts extra stress on the power grid, in an era when electricity is one of the most important commodities for economic, industrial and everyday ...

  • 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 ...

  • Artificial neural network based models for forecasting electricity generation of grid connected solar PV power plant

    This paper presents an artificial neural network (ANN) approach for forecasting the performance of electric energy generated output from a working 25-kWp grid connected solar PV system and a 100-kWp grid connected PV system installed at Minicoy Island of Union Territory of Lakshadweep Islands. The ANN interpolates among the solar PV generation output and relevant parameters such as solar ...

  • Study: Climate change could overwhelm U.S. electrical grid

    Climbing temperatures associated with global warming could wreak havoc on the U.S. electrical grid, according to a new study on the economic and social costs of climate change. Published last week in the scientific journal Proceedings by researchers at the University of California-Berkeley, Stanford, and University of Michigan, the study says the country will need to spend at least $180 billion ...

  • Smarter grids, appliances, and consumers

    More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system. Existing electricity grids are typically a patchwork of local grids that are simultaneously inefficient, wasteful, and dysfunctional in that they often are unable, for example, to move electricity surpluses to areas ...

  • Grid integration of renewables in Egypt

    Integration of large Amounts of Renewable Electricity in the Egyptian Energy Grid - Capacity Building for Management and Engineer-Technical Level (Egypt-RE-Grid). The electricity sector of the Arab Republic of Egypt produces large amounts of electricity through thermal and hydroelectric power stations. Egypt has diminishing proven oil reserves and declining production. Natural gas production is ...

  • The Grid vs. Rooftop Solar

    The development of solar micro-grids and mini-grids in the remotest parts of Australia seems to be a rational step in the right direction economically. However, network operators all over the world are still in doubt when it comes to the vast population in urban areas adopting similar methods. The question lies with the homeowner choosing to buy the necessary power generating equipment ...

  • The Economics of Grid defection

    Distributed electricity generation, especially solar PV, is rapidly spreading and getting much cheaper. Distributed electricity storage is doing the same, thanks largely to mass production of batteries for electric vehicles. Solar power is already starting to erode some utilities' sales and revenues. But what happens when solar and batteries join forces? Together they can make the electric grid ...

  • Electric vehicles powering communities through natural disasters

    Mass power outages and blackouts have always been of great concern during and after natural disasters. In addition to the devastation that can occur from flooding, collapsed buildings, and disruptions to basic infrastructure, the absence of electricity can shut down basic communications systems, adding to the anxieties of those most critically affected. While much discussion revolves around what ...

  • A perspective overview of topological approaches for vulnerability analysis of power transmission grids

    Vulnerability analysis is a key issue in power systems since power transmission grids play a crucial role as a critical infrastructure. The power grid structure (number of nodes and lines, their connections, and their physical properties and operational constraints) is one of the main factors to assure power system security. Complex network theory as a promising topological approach for the ...

  • Correlating empirical data and extended topological measures in power grid networks

    Power grids are considered complex networks. Their structure and dynamics have been thoroughly studied and many topological measures have been used to classify them, evaluate their behaviour or model their response to malfunctions. Results have been theoretical and correlations between real dynamical behaviour (i.e., major events) and structural measures have not yet been found. New electrically ...

  • Ships that harvest electrical power from ocean waves

    Electrical power generation from ocean waves is possible from ships that harvests wave energy through daily trips to offshore locations and that return back to port for the delivery of energy to the grid. Energy is stored locally on the vessel during harvesting phase and placed on the grid during periods of high demand (normally mid-day). Unlike conventional wave-power devices, the ships ...

  • Reciprocally altruistic agents for the mitigation of cascading failures in power grids

    Cascading failures in electrical power networks often come with disastrous consequences. A variety of schemes for mitigating cascading failures exist, but the vast majority depend upon centralised control architectures. Centralised designs are frequently more susceptible to communications latency and bandwidth limitations and can be vulnerable to random failures and directed attacks. This paper ...
