Realistic data needed to evolve the 21st century power grid

Say you have a great new theory or technology to improve the nation's energy backbone—the electric grid. Wouldn't it be great to test it against a model complete with details that would tell you how your ideas would work? ...

Charging an electric car as fast as filling a tank of gas

Electric cars will only be truly competitive when it doesn't take longer to charge them than it does to fill a gas tank. The storage capacity of batteries is improving exponentially, but the power grid is the weak link: how ...

Extreme weather poses increasing threat to US power grid

When Hurricane Katrina's punishing storm surge plowed ashore, it swamped seven of Coast Electric Power Association's substations, vital to powering thousands of Mississippi homes and businesses. The facilities have long since ...

Smart Grid can help with prime-time charging of EVs

Norway leads the world in new car sales of electric vehicles, but how will charging all those EVs affect the Norwegian energy supply? Researchers at the Norwegian University of Science and Technology are helping to develop ...

Investigation: US power grid vulnerable to foreign hacks

Security researcher Brian Wallace was on the trail of hackers who had snatched a California university's housing files when he stumbled into a larger nightmare: Cyberattackers had opened a pathway into the networks running ...

Railways: Ensuring readiness in case of space weather events

The JRC has been looking into the risks of space weather impact on critical infrastructures. A new report explores the rail sector's vulnerability and the potential impacts, in particular through interdependencies with other ...

Enlisting distributed energy devices to balance the power grid

The electric grid has to balance power supply and demand nearly in real-time, requiring power plants to be adjusted on a second-by-second basis. This instantaneous balance is made significantly more complex by renewable energy ...

Toward a more resilient and flexible power grid

"The biggest and most complex machine ever built by humankind." That is how University of Wisconsin–Madison doctoral student of electrical engineering Philip Hart describes the nation's power grid.

Three new technologies to make energy cleaner, more efficient

Three technologies - a computational tool to improve power grid planning, a process to create biofuel from kelp and a hybrid device that makes hydrogen and stores energy - are being developed by Pacific Northwest National ...

How solar panels are making waves

If you think of electrical current flowing like water from the grid to your home, you can start to imagine the waves your rooftop solar panels create when they try feeding current in the opposite direction.
