Short description
Prof. Dr.-Ing. Ilja Tuschy was appointed Professor of Power Engineering in Mechanical Engineering at Flensburg UAS, now Flensburg University of Applied Sciences, in 2006. For more than 20 years, he has been involved in industry and science with the development, design and analysis of plants for the supply of electricity and heat. His work focuses on energy system analyses of power plant and other coupling processes as well as energy supply systems with storage components, such as compressed air storage power plants, CHP and power-to-heat plants, and heat grids with solar and geothermal elements and heat storage systems. Their operation is simulated on a component basis, evaluated techno-economically in the context of the surrounding energy supply system and optimized numerically. Ilja Tuschy is a founding member of the Center for Sustainable Energy Systems ZNES of the two Flensburg universities and heads the Thermal Energy Systems department there.
