Failures in power grids: Dynamically induced cascades

A reliable functioning of technical infrastructure networks is essential for our modern, high-tech society. Cascading failures, i.e. chain reactions of failures of different infrastructures, are the cause of many failures ...

Live, precise recording of grid voltage and load currents

Researchers of Karlsruhe Institute of Technology (KIT) have developed a novel monitoring and analysis tool for electrical power grids: The EDR – Electrical Data Recorder continuously scans grid voltage and load currents ...

Symmetry is essential for power network synchronization

A joint research team from Tokyo Institute of Technology (Tokyo Tech) and North Carolina State University has clarified the fundamental principles for achieving the synchronization of power generator groups in power networks, ...

Simple grid increases fuel cell efficiency by over 30 percent

TurbuGrid is the name of a small plastic grid approximately 16 x 16 cm that can markedly increase the efficiency of an air-cooled fuel cell stack. Tests by AAU researchers show an increase in efficiency of at least 33.5 percent, ...

Intelligent components for the power grid of the future

Fast charging of electric cars requires a lot of energy in a short period of time. These peak loads lead to bottlenecks in the power grid, and are one of the problems facing the expansion of electric mobility. The many challenges ...

Buzz feed—bringing renewables to the power grid

Renewable energy is on the rise in Europe as the economy develops away from the use of fossil fuels such as coal and oil, but an ageing electricity grid is struggling to keep up with the rapid pace of developments.

Space weather threatens high-tech life

Shortly after 4 a.m. on a crisp, cloudless September morning in 1859, the sky above what is currently Colorado erupted in bright red and green colors. Fooled by the brightness into thinking it was an early dawn, gold-rush ...

Mastering the future power grid
