Avoiding blackout – with data
On 8 January 2021, Central Europe was on the verge of a large-scale power blackout. Leonardo Rydin Gorjão from the Institute of Energy and Climate Research (IEK-STE) analyses data that are expected to help prevent such situations.
You have been involved in building a database of worldwide frequency measurements in power grids. What are its benefits?
Small frequency deviations occur in the power grid all the time. Thanks to our database, we can analyse these. This way, risks can be identified and control mechanisms improved in order to prevent excessive frequency interference and, thus, a blackout.
A first analysis of the data is available. What does it reveal?
Frequency interferences in the same grid at widely separated locations such as Istanbul, Karlsruhe and Lisbon influence each other. We have identified how quickly these disturbances subside. The analysis also shows that threatening fluctuations can occur especially in micro and island grids.
Why is it important that your data is publicly accessible?
In socially significant research areas in particular, it is important that all researchers can compare and review data. Open data also facilitates collaboration across disciplines and countries.
