Current status of peer to peer microgrid implementation

Current status of peer to peer microgrid implementation | Thermal to electric conversion | Scoop.it

“According to Shahidehpour, what makes the new generation of microgrid applications worth paying attention to is that that the elements of a modern microgrid have themselves gotten smart, to the point where they can easily shift loads based on different needs and desired outcomes. “The customer decides when he wants to use power, how much he wants to use.” In this way, a smart microgrid “empowers smart users.”

New materials for future green tech devices

New materials for future green tech devices | Thermal to electric conversion | Scoop.it

 From your hot car to your warm laptop, every machine and device in your life wastes a lot of energy through the loss of heat. But thermoelectric devices, which convert heat to electricity and vice versa, can harness that wasted heat, and possibly provide the green tech energy efficiency that's needed for a sustainable future.

Now, a new study shows how porous substances can act as thermoelectric materials—pointing the way for engineering the use of such materials in thermoelectric devices of the future.

About 70 percent of all the energy generated in the world is wasted as heat, said Dimitris Niarchos of the National Center for Scientific Research Demokritos in Athens, Greece. He and Roland Tarkhanyan, also of NCSR Demokritos, have published their analysis in the journal APL Materials, from AIP Publishing.

Microgrids and Municipalization: Can You 'Micro-Municipalize' a Utility? - Greentech Media

Microgrids and Municipalization: Can You 'Micro-Municipalize' a Utility? - Greentech Media | Thermal to electric conversion | Scoop.it

Microgrids can aggregate complementary distributed energy resources. Through the matching of supply and demand resources within a given microgrid, it is possible to tailor the performance of that network to provide specific operating or environmental performance characteristics. For instance, individual microgrids can be designed for interruptibility, or efficiency of generating sources and loads, or a specific level of reliability and power quality, or an environmental emissions profile, or even to maximize economic value by selling services to the macrogrid. In this way, microgrids make a fairly commoditized electricity system customizable to the quality needs of an individual customer.

MicroGrids Would Enhance Smart Grids | EnergyBiz

MicroGrids Would Enhance Smart Grids | EnergyBiz | Thermal to electric conversion | Scoop.it

Before there was the grid, there was the microgrid.

 

Electrification in the United States often proceeded from a diesel generator and local distribution in an isolated town to the development of the big utilities and complex grid of generation, transmission and distribution of the 21st century.

 

Now, however, a convergence of smart grid technology, renewable energy development, and an increasing number of weather-related grid outages is sending us back to the future and a new kind of microgrid.

 

"Microgrids are the killer app for smart grids," says Terry Mohn, chief executive of General Microgrids, which designs and builds microgrids around the world.

 

Digital demand management makes it possible to juggle power generated from variable renewable sources like solar and wind, natural gas generation, stored energy and the grid to distribute power and other forms of energy through a local network. 

 

Strategic energy objectives like developing storage capacity, increasing energy efficiency, and using new tools for demand management and prioritizing loads are all served by microgrid development, Mohn says.

 

The notion is beginning to take hold across the country, from a pilot project at the University of California at San Diego to a new initiative by the state of Connecticut as a way to improve power reliability and achieve greater penetration of renewable energy sources.

 

"It is one new element to help power resiliency," says Brad Luyster, who heads ABB's marketing push for microgrid development. "Microgrids are going to explode."

Soon everyone will be an electric company - MarketWatch

Soon everyone will be an electric company - MarketWatch | Thermal to electric conversion | Scoop.it
In the not-too-distant future, everyone could be an electric company, selling power into the grid just like the owners of giant generating plants.
The idea of powering the electric grid from a multitude of sources is called distributed generation.

Via Microgen Concepts
Alain Coetmeur's insight:

The idea is real but the technology is not the one LENR will requires.

LENR distributed electricity will be based on LENR-CHP and migro-generators. Storage won't be needed really, except maybe for some short peak if there is no grid to share them, requiring ultra-capacitors and not classic batteries.

Question about maintenance and repairs will give birth to a huge industry. question between micro-grid between neighbors and no-grid, will either develop smart-grid technology, or backup/tandem technology.

 

Question will appear also for industry, for big buildings, city districts, villages, road infrastructure, which could benefit of large smartgrid, departmental generators, waterfall, road-grid, solar panel... the end of the one size fits all.

 

nearly nothing is anticipated currently. Funny to see how ALL prediction will be broken. As Taleb says, is it worth predicting ? Is it not better to be ready, and wait for any expected or unexpected problem to appear, instead of mixing fear and hope to lead us to the wrong direction.
