Fraunhofer Institute for Wind Energy Systems - Fraunhofer IWES (Coordinator)

The Fraunhofer Institute for Wind Energy Systems IWES conducts application-oriented research for a sustainable future. The focus topics of the Fraunhofer IWES are offshore, hydrogen, test infrastructure and digitalization. The research work in these future-oriented key technologies plays a central role in the innovation process and strengthens the business location for the benefit of our society by transferring the research results to industry. More than 400 employees at nine locations are developing innovative methods to accelerate the expansion of the wind energy and hydrogen economy, minimize risks, and increase cost efficiency. The team Integration of Local Energy Systems (ILES) participating in TenSyGrid, has a special focus in developing new modelling and control techniques to enable the integration of local energy systems to the grid.

Universitat Politècnica de Catalunya · Barcelona Tech - UPC

The Polytechnic University of Catalonia (UPC) is a public institution of research and higher education in the fields of engineering, architecture, sciences and technology, and one of the leading technical universities in Europe. The AC/DC grids and electric power conversion group of the research and technology transfer center CITCEA-UPC (co-led by Eduardo Prieto-Araujo) has wide experience in the analysis of modern power systems dominated by renewable generation and power electronics, which they acquired through their participation in several competitive and industrial projects.

eRoots Analytics - eRoots

eRoots is a spinoff company of CITCEA-UPC whose aim is to bring the ideas developed there to the market in the form of products. eRoots specializes in performing electrical studies for modern power grids, especially those with numerous converters. One of the other core activities of eRoots is the development of software for grid operators, that is, tools that are both useful for steady-state and dynamic analysis.

Hamburg University of Applied Sciences - HAW

The Hamburg University of Applied Sciences (HAW Hamburg) is a higher education and applied research institution located in Hamburg, Germany. The expertise of Gerwald Lichtenberg’s team at the HAW Hamburg in multilinear modelling is unique in Europe, particularly for applications like controller design and fault diagnosis. Furthermore, they have developed a toolbox for multilinear time-invariant system modelling and controller design (MTI Toolbox). Up to now, the HAW has applied multilinear modelling techniques to small or medium size HVAC systems in various projects. Today, the HAW focuses on extending the multilinear modelling framework to large-scale systems as well as deeper analysis methods.

University of Malta- UM

University of Malta (UM) is the leading higher education institution in Malta fostering academic research and a higher education setting in the arts, sciences and the humanities as required for Malta’s economic, social and cultural development. The UM TenSyGrid team lead by John Licari is actively involved in state‐of‐the‐art research in power systems, microgrids and smart grids, power electronic converters, renewable energy systems for grid integration, and energy storage and electric transportation.
