On September 11, 2016, the Energy Campus Nuremberg presented research projects and their applications at the “Open on AEG” event. The Chair of Computer Science 7 gave interested citizens an insight into the current research in the field of smart energy systems. With efficient simulation tools, energy systems are modeled from a single household to residential areas, distributed battery systems, industrial processes up to the entire electrical power supply. The efficiency potential for the use of renewable energy sources as well as of storage systems is determined and as a result an economic design is made possible.
