The LLEC project develops highly integrated energy supply systems in the sectors of heat, electricity, chemical energy storage and mobility based on adaptive and predictive control strategies. The goal is to create an intelligent energy system that takes equal account of the issues of sustainability, economic efficiency and user comfort. To this end, a real laboratory is being built on campus to test the building blocks and their interaction for the energy system of the future. A project team from a wide range of disciplines has joined forces and will report here on its progress.
