Better power grid synchronization may enable smart grids to self-recover from failures
Wind turbines operate under great turbulence, with consequences for grid stability
Electric vehicles could stabilize large disturbances in power grid
Power grid upgrades may cause blackouts, warns Braess's paradox
Satellite proposed to send solar power to Earth
Big solar storm smacks Earth, may allow more to see auroras
A severe solar storm slammed Earth on Monday afternoon, increasing the chances of fluctuations in the power grid and GPS. It also pushes shimmering polar auroras to places where more people can possibly see ...
The sun also flips: 11-year solar cycle wimpy, but peaking
(Phys.org) —In a 3-meter diameter hollow aluminum sphere, Cary Forest, a UW-Madison physics professor, is stirring and heating plasmas to 500,000 degrees Fahrenheit to experimentally mimic the magnetic ...
New battery design could help solar and wind power the grid
(Phys.org) —Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind ...
Engineers craft new material for high-performing 'supercapacitors'
Taking a significant step toward improving the power delivery of systems ranging from urban electrical grids to regenerative braking in hybrid vehicles, researchers at the UCLA Henry Samueli School of Engineering ...
Physicists suggest electrical networks more at risk of cascading failure than thought
Privacy group gets NSA files on utility research
Tiny bubbles snap carbon nanotubes like twigs
What's 100 times stronger than steel, weighs one-sixth as much and can be snapped like a twig by a tiny air bubble? The answer is a carbon nanotube -- and a new study by Rice University scientists details ...
Some suggest it's time to rethink which direction we point our solar panels
Engineer says 'smart grid' needed for shift to alternative energy
(Phys.org) —Electrical grids are balky beasts, and nobody knows that better than Stanford Assistant Professor of Civil and Environmental Engineering Ram Rajagopal. He grew up in Brazil, where no one took ...
