About the project
FLEXDIS aims to enhance power system stability and flexibility in the face of high distributed renewable integration. Its objectives include assessing frequency and voltage impacts on grids, enabling flexible operation of inverter-based resources, and classifying heating types via machine learning. The project quantifies flexibility from thermal storage, buildings, and EVs, and studies Termonets’ potential to provide ancillary services without reducing comfort. It promotes citizen involvement through EV charging and community networks, verifies solutions through hardware-in-the-loop and living labs, and strengthens TSO-DSO coordination for robust operation.
FLEXDIS will deliver concrete solutions to enable high penetration of distributed renewables while safeguarding grid stability. Expected results include improved fault ride-through controls for inverter-based resources, reducing disconnections and cascading failures, thus enhancing security of supply and lowering costs. Active loads such as EVs, heat pumps, and Termonets will provide fast reserves without affecting comfort, creating a new flexibility source validated in living labs. The project will define new specifications and standards for IBR controls, ensuring voltage and frequency support at distribution level, and provide recommendations for harmonized practices. Finally, stronger TSO–DSO communication protocols will be established to improve coordination, market integration, and contingency management, reinforcing overall system resilience.
