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 ...

Sainsbury’s to cut energy costs with new intelligent building
Retail giant will start using a smart-grid system at Kent store on Wednesday as part of another green initiative to cut carbon emissions. Sainsbury’s will start testing a smart-grid system at its new Hythe store in Kent on Wednesday, in an attempt to cut its carbon emissions and reliance on the grid at times of peak demand. The company said the smart grid system technology was a ...

Hybrid tower
Using the Torque Wind Turbine in combination with solar and a battery pack could give the opportunity to build a smart grid. This way houses, companies, farms and small villages could become self-supporting in energy and create a smart grid using Internet of Things applications and 5G telecom options directly from the Torque Wind Turbine tower. Also the battery of electric cars for electricity ...

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 ...

Design and implementation of a bidirectional isolated DAB–based DC/DC converter for battery system
A home area network (HAN) incorporating a high–power high–efficiency charging/discharging battery system is capable of executing energy saving strategies in the smart grid, such as TOU or DR. This paper presents a bidirectional isolated DAB–based DC/DC converter for a Li+Fe battery system in the HAN. Battery energy is controlled by the phase angle between the primary bridge and the secondary ...

A sociotechnical systems model for smart-grid adoption in mid-sized urban environments
In this paper, we present a quantified system dynamics model simulating the adoption of smart grid technologies such as electric vehicles, PV systems and smart meters in a mid-sized urban system and the resulting impact on the CO 2 emissions. We also analyse the impact of different subsidies on the adoption and calculate the effectiveness regarding public and private spending on these ...

Smart Grids – The Governmental Approach
Scott Blake Harris is the General Council for the US Department of Energy, and has recently spoken out at the NGU US summit (hosted by GDS International). He was nominated in the position by President Barack Obama in March 2009, and was confirmed by the United States Senate in May 2009. He focused his address on the $4 billion investment into smart grids and renewables across the US. Scott ...

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 ...

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 ...

Video Reveals the Truth About Smart Grid
We don’t think about energy until something goes wrong, and this week things went wrong on an historic level. As a result, the public and pundits are again focusing on the fragility of big electric grids. Ten percent of the world’s population – more than 600 million people – lost their power in India on July 31, marking the largest blackout in history. India’s grid ...

GE, Glen Dimplex to team on smart grid in Europe
General Electric Co. (GE) and Glen Dimplex, a European home heating and appliance company, have signed a joint development agreement under which the two companies will make smart grid technologies available to European homeowners. Under the agreement, Glen Dimplex and GE will develop ways to integrate GE’s Brillion home energy management technologies into Glen Dimplex’s home heating ...

A new time–frequency approach for hybrid differential and impedance protection of transmission lines
A new current differential protection of transmission lines is presented in this paper using an S–transform variant having very fast computational speed suitable for real–time applications. The conventional S–transform used earlier for transmission line protection has large computational overhead and thus is not suitable for generating decisions regarding the occurrence of a fault and its type on ...

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 ...

State of the Smart Grid Business in 2013
Smart Grid sales across the world in the last 3 years at installed prices have grown by CAGR of approx. 35% and climbed to $36.5 billion in 2012. Given the general global economic demise during this period these figures are remarkable. However they include a steady flow of refurbishment business that has for more than 10 years incrementally improved and smartened up the control and reliability of ...

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 market is, well, golden. ...

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 ...

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 ...
