By 2030, the EU has a binding target that the share of electricity produced by renewables must grow to 50 %. The EU-funded FLEXIGRID project is developing solutions that will protect the security and reliability of the electricity grid as it incorporates growing amounts of renewable energy. It aims to make the distribution grid operation more flexible and cost efficient through the development of four hardware and four software solutions. A single, open-source platform will integrate the different solutions and make them interoperable with the IT systems used by energy stakeholders. The project has defined eight use cases that will be demonstrated in four countries. The demonstration sites will be operated by three distribution system operators and two large companies.
