Sustainable Energy Systems

The Sustainable Energy Systems research group seeks ways to increase the flexibility, efficiency, sustainability, reliability and social acceptance of increasingly complex and dynamic energy systems, which will be mainly powered by renewable energy sources such as solar energy, wind power or bioenergy.

It aims to bridge the gap between existing technologies and globally optimized, smart solutions for the future. In this way, the research team is focused on developing ground-breaking solutions for the challenges of future energy systems, allowing for the larger integration of renewable energy, energy storage, demand response and electric mobility including energy communities, resilient networks and efficient intelligent buildings, without forgetting system security assessment and model/data interoperability.

The research group will also work towards providing solutions to new and existing challenges in markets (local and global), including developing mathematical models to analyse market operations and proposing new market designs.
