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 with high precision and high resolution. While power generation from renewable sources by decentralized producers is increasing, the EDR will provide deeper insight into real systems processes in the future. The data measured will enhance the quality of simulations and enable reliable control of future smart grids.


Electrical power supply is changing: The more the energy transition advances, the more power from volatile renewable sources, such as sun and wind, is fed into the grid, often by decentralized producers. As a consequence, the power grid has to balance locally varying production and load situations in order to maintain reliable supply. To this end, smart grids will interconnect producers, storage systems, and consumers via information and communication technologies and adjust them to each other in the future.
