Overall aim
FLEXDIS aims to enhance grid stability by analysing the impact of high distributed renewable generation on voltage and frequency stability. The project will explore flexibility from demand, thermal energy networks, storage, and EVs to provide additional power reserves. It will propose improvements to grid connection requirements, IBR controls, and TSO-DSO coordination to prevent cascading failures and support system stability.Â
The main objectives of FLEXDIS are as follows:
O1: Evaluating the impact a high amount of integrated distributed renewable generation has on the
transmission and distribution grid in terms of frequency and voltage stability.
O2: Enabling flexible operation from IBRs connected at the distribution grid in order to increase grid
stability and to limit cascading failure events.
O3: Applying machine learning algorithms for classifying consumer/prosumer heating type.
O4: Quantifying the reserve capability from thermal energy and storage in buildings and electric vehicles
at distribution level.
O5: Evaluating the potential of Termonets from local communities to provide ancillary services without
affecting consumer comfort.
O6: Active involvement of citizens, e.g., households, through Termonets and EV charging facilities to
integrate flexibility to power grids
O7: Verification of proposed flexibility solutions from generation and demand side in hardware-in-theloop experiments considering real grid data as well as by test on real living lab buildings.
O8: Dissemination of the project results in the scientific and the CETPartnership Knowledge Community
within the field of active distribution grids.
O9: Improving communication and interactions between transmission and distribution system owners to
achieve robust grid operation.
