Building hybrid grids for a resilient and sustainable energy future in Europe
Europe’s energy system faces major challenges: rising energy demand, climate change impacts, and the need for greater integration of renewable energy sources. THEUS seeks to revolutionize European grids by advancing on resilient, interoperable AC/DC hybrid systems, incorporating advanced planning and design methodologies, innovative operational grid technologies, and robust protection systems. By pioneering new tools and technologies, THEUS paves the way for a reliable, carbon-neutral, and interconnected European energy network.
About THEUS
The proliferation of DC grids is considered a promising solution due to their numerous benefits regarding the integration, transport, and distribution of renewable energies.
