Efficient power grids are an essential prerequisite for a successful conversion of the energy system. In order to support work on the power grids of the future, the Federal Ministry of Education and Research (BMBF) is extending the funding of an interdisciplinary research project by three years, in which seven institutes, including the Frankfurt Institute for Advanced Studies with Professor Stefan Schramm, are involved. The joint project is funded by the BMBF with a total of 2.5 million euros.
