  • GIVS: integrity validation for grid security

    In recent years, grid computing has been recognised as the next step in the evolution of distributed systems. However, only limited efforts have been made to address the security issues involved in these architectures. Questions like 'What happens if a user of the grid is interested in making the overall computation fail?' are still unanswered. In this paper, we address the problem of granting ...

  • Integration of embedded generation in local grid using STATCOM

    The renewable sources of energy are being connected to the local distribution system/local grid leading to embedded generation. As these sources are intermittent in nature, they impose technical challenges in the power system operation which include power quality related problems of local grid. The performance of the system has to be evaluated while connecting these sources to the local ...

  • 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 ...

  • Wanted: GOLD for smart grid

    As John McDonald tells it, smart grid needs GOLD. And he’s not talking money. GOLD stands for Graduates of the Last Decade, the technology savvy, risk-taking engineers and technicians who may be among the greatest benefactors of the new smart grid movement. While most recent college graduates face dismal employment prospects, for the GOLD kids, the job ...

  • 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 ...

  • 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 ...

  • Integration of wind-generating units into the Corsican electrical grid: determination of the maximal integration rate from a reliability analysis based on a stochastic process

    This paper investigates the potentiality of Wind Electric Conversion Systems (WECS) integrated into the islander electrical grid of Corsica. Probabilistic models for WECS and their use in the reliability studies of combined wind electric and conventional generation systems are discussed. The method, based on the evaluation of the Loss of Load Probability (LOLP), uses a Markov model applied to the ...

  • A comparative study on the grid integrated wind energy conversion systems (WECS) using different generator models

    A huge number of wind generators are going to be connected with the existing network in the near future. Therefore, it is necessary to analyse various models of wind energy conversion systems (WECS) for the purpose of studying the impacts upon grid. This paper presents comparative study on grid connected WECS having two different wind turbine generator systems (WTGS): model 1 [WTGS having doubly ...

  • Economics of large-scale intermittent RES-E integration into the European grids: analyses based on the simulation software GreenNet

    Market integration of Renewable Energy Technologies for Electricity (RES-E) generation is one of the core topics in the energy policy agenda of the European Commission (EC). However, legislation in this context still faces a variety of lacks (e.g. ignoring unbundling principles) in almost all countries of the European Union (EU). The recently finished EC-Project GreenNet addresses these existing ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Looking forward to the day smart grid dies

    The title of this blog might strike you as kind of weird, especially this week. After all, the Electric Power Research Institute made the news with a study showing that smart grid is going to be far bigger than we first thought. Smart grid in simplest terms brings to the electrical grid the digital intelligence of computers and the Internet. Just seven years ago EPRI expected smartening the grid ...

  • 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, ...

  • Community-coupled microgrids for the implementation of a smart grid in Tunisia

    Smart grids are based on the use of ICT in order to optimise the quality and the cost of electricity generation, transport and distribution. Developing countries try to upgrade their electric grids to meet the evolving needs of the end consumers and face the energy challenge. The study of smart grid instauration in such countries must consider the disparity in terms of ICT infrastructures across ...
