Flexigrid is an innovation project funded by EU´s largest research and innovation program Horizon 2020. The project will create an enabling architecture for small and medium Distribution System Operators (DSOs) to unlock flexibility resources. Through a cross sectoral integration and optimizing of resources, especially those existing in the coupling between different energy vectors, as well as demand response using charging schemes of electric vehicles (EVs) or storage, DSOs will be able to meet the forthcoming capacity shortage with flexibility and updating old systems with smart technology. In Flexigrid organizations from all over Europe cooperate to leverage digital and smart grid technologies at the grid edges. The project will deliver IoT platforms, peer-to-peer and peer-to-pool marketplaces, vehicles-to-grid, power-to-heat and power-to-gas solutions, as well as innovative business models. Flexigrid will equip DSOs with advanced tools to enhance observability and controllability of distribution networks, while demonstrating both pool-based and peer-to-peer market mechanisms. From these market implementations further development will demonstrate a flexible DSO-Customers coordination platform for efficient real-time trading of energy and grid services between market actors. This project has received funding from the European Union's Horizon 2020 research and innovation programme under the grant agreement No 864048.
