The department “Integrated Energy Systems“ explores the transition of existing energy systems with two research foci: Energy Economics and Energy System Technology.

In the field of Energy Economics, models for the mathematical description of energy systems are developed, and the static and dynamic behaviour of the system is investigated. Optimum designs of future energy systems are identified by the application of optimization methods and agent-based models that take into account technical constraints as well as micro economic, macro economic, and behavioural aspects. From these results we identify recommended actions for the stakeholders, technical designs and recommendations for legislation and market regulations.

Energy System Technology considers the technological aspects of the energy system that mediate between energy generation and energy consumption. These encompass the energy transporting grids for electricity, heat and gas, but also the communication grids that carry the information required for the operation of the energy system. The department’s focus is on the latter, the communication grids. Furthermore, automation of technological components and automation of the business processes are part of the research agenda.

Furthermore, the group "Integrated Energy systems" is a linking part between Universität Kassel and Fraunhofer Institute for Energy Economy and Energy System Technology (IEE). Fraunhofer IEE explores systemic aspects of the transition of the energy sector in Germany and world wide.
