In the renewable energies era, grid frequency will be an increasingly important indicator of stability of power supply. Under the direction of the Helmholtz Association, an interdisciplinary research consortium has analyzed frequency fluctuations in twelve synchronous grid areas on three continents. For data recording, scientists of Karlsruhe Institute of Technology (KIT) have developed a portable, GPS-synchronized recorder based on a new measurement technology. First results have now been published in

Researchers have created a database of measurements from existing global power grid systems that will help develop new power systems capable of meeting changing demands, such as the move towards renewable energy sources.
The study, published in
Nature Communications, is the first step towards a more collaborative approach to energy research. It is hoped the publicly available data can be used worldwide to design and test new energy concepts in response to current and future challenges.
For the study, the researchers collected power grid data from 17 locations across three continents and covering 12 synchronous areas - regions containing different power plants and consumers that are connected and operate under the same frequency.
