Kick-off for Redispatch 3.0 research project with emsys grid services

Together with fifteen partners, including the German transmission system operators and numerous distribution system operators, emsys grid services GmbH is part of the Redispatch 3.0 research project launched in January 2022. The project aims to improve the integration of low-voltage systems and the cooperation and exchange of information between the various grid operators. The goal is to further develop the concepts gained from the recently introduced German Redispatch 2.0 regulation and to implement, test and evaluate the resulting approaches on a pilot basis.

Congestion management in electricity grids was previously the sole responsibility of transmission system operators. Due to the increasing decentralisation of the electricity supply and the need to integrate volatile energy producers, the regulatory framework and the previous procedure for grid operation have been adapted: in the amendment to the Grid Expansion Acceleration Act (NABEG 2.0). So-called redispatch measures aim to avoid grid bottlenecks across all voltage levels and thus make the electricity grid more efficient, economical and resilient. Under Redispatch 2.0, renewable energies and CHP plants from 100 kW and controllable loads of more than 30 kW can be remotely controlled by grid operators. However, the potential of prosumers at the low-voltage level so far has not been utilized. In the future, the transmission and distribution grid operators will forecast corresponding redispatch potential and requirements in order to increase transparency and flexibility potential at all voltage levels.

The joint project is funded by the Federal Ministry for Economic Affairs and Climate Protection. It is being coordinated by the OFFIS research institute, an affiliated institute of the Carl von Ossietzky University of Oldenburg, and is being carried out with partners including PSI GridConnect, KISTERS, EWE Netz, MVV Netze, the Fraunhofer Institute, TenneT TSO, 50Hertz and TransnetBW.
