post sandy, u.s. pushes microgrids for backup power - storage battery systems

From the army to the main street, the United States is trying to avoid the Sandy storm.
Like a power outage, by developing more backup power supplies in the form of a micro-grid, many of these small networks produce power on site and store it for an emergency.
They operate independently of the State Grid, which distributes electricity from coal, natural gas or nuclear power plants, so they can keep the lights on when the storm destroys the grid.
Just a year after Sandy turned off the No. 8 light.
5 million of Americans are increasingly combining generators, fuel cells, solar panels paired with batteries, and thermal and power technologies.
These different micro-grids are designed to make the main grid more "flexible"
2013 buzzwords of energy.
"Sandy changed the rules of the game," said Tom Leiden, CEO of solar grid storage, which developed a battery system to store solar energy, which fluctuates throughout the day.
He said the big storm
With the decline in the price of solar energy, the improvement of batteries and the increasing problem of climate change,
The need to store renewable energy has expanded, and this has begun to transform the utilities industry. On Oct.
California became the first AmericanS.
The state requires utilities to maintain a certain amount of energy storage.
On July, the Federal Energy Regulatory Commission issued an order urging utilities to pay higher prices to the micro-grid for backup power, which they can quickly provide the main grid.
Phyllis Cuttino, director of clean energy projects at Pew Charity Trust, said: "There is more concern about grid reliability . " He added that Sandy has also shown for decades
Old technologies such as thermal power (CHP)
Can save a day.
After Sandy, New York University and South Oak Hospital on Long Island did not get dark because of their health protection system --
Also known as co-generation —
Do not extract electricity from the grid, but generate electricity on site by reusing the energy that is usually wasted during the power generation process.
Although most of them are tied to the grid and can improve their efficiency, some microgrids operate completely independently. Off-
A grid house with rooftop solar panels, or a grid house with a backup generator, is essentially a "nano" grid. Microgrids —
Used mainly by universities and hospitals.
With the development of the US economy, it is now expanding into other facilities. S.
The Ministry of Defense, businesses and local governments are working to avoid the risks posed by extreme weather, which is expected to intensify with climate change
Related power risks. More than 50 U. S.
According to Article 4, military bases are now operating, planning, or are testing the Microgrid
The 2013 quarter data released by the research team navigation consulting company responsible for preparing the microgrid database.
Peter Asmus, chief research analyst at Navigant, said: "So far, the United States is the world leader in the micro-grid field . ".
He said that there are now nearly two in this country.
Thirty or 62% of the global planned or operated microgrid capacity.
He said the number of global microgrids has increased from about 400 at the beginning of last year to about 600 now, nearly half of which are in the United States. S.
Asmus said Sandy and other recent extreme weather events have exposed the increasing unreliability of the National Aging and "balkanized" grid, which is affected by different statesby-
State regulations.
Affected by Hurricane Irene's power outage in 2011, kangzhou passed a law last year to launch the first statewide micro-grid project to ensure continuous power supply to urban centres and other key facilities.
"In our efforts to modernize and harden our infrastructure to withstand bad weather, the micro-grid has played an important role," said the Democratic governor of Connecticut.
Dannell mallolay announced nine pilot projects in eight cities in July.
The project will use cogeneration systems, natural gas turbines, fuel cells and solar panels.
Some combinations.
Last month alone, the governors of New York and New Jersey also announced additional funding for their state's micro-grid projects, both hit by Sandy.
In August, the US Department of Energy said it would work with New Jersey to develop the first micro-grid for the US. S. transit system.
They call it "NJ TransitGrid" and have gained expertise in the Department of Energy Sandia National Laboratory, which has designed advanced micro-grids in more than 20 USS. military bases.
"I think this will be a model for this country . "J. GOP Gov.
Chris Christie said at the announcement event of N. Secaucus. J.
The meeting was attended by Energy Minister Ernest Moniz.
S. Department of Defense and Energy are trying to standardize micro-grid technology, and they are working with SAIC, Lockheed Martin and General Electric.
San Diego, August-
San Diego-based Power Analytics has announced that it will install its software at a naval facility in San Diego County, which manages the micro-grid by determining how the storm can temporarily best use the backup Power supply.
The private sector is also adopting micro-grids.
Earlier this month, Mr. bafflin said he would install the Bloom Energy fuel cell at a data center in Irvine, California.
To generate enough power to protect critical loads from downtime.
On September, Maryland developer Konterra installed a solar micro-grid project at its headquarters in Laurel, Maryland.
Although the micro-grid has been greatly promoted, obstacles still exist.
Some states, including New York, do not specify what they are, so their legal status is unclear.
In addition, the federal tax benefits for some of the ideal micro-grid technologies, including CHP, will expire at the end of 2016.
"Any shift will take time," Leyden said of the bumps on the road . ".
"That's what we're going through.
