Communal Energy Supply Systems "KESS“

In the interdisciplinary project KESS, technologies and concepts for flexible power production, distribu-tion and storage in interconnected, peripheral systems are investigated. The project’s objective is to provide an energy supply system, which is adapted to local circumstances, such that local energy needs and regionally available sources of energy can be integrated. This is shown in the figure below by the example of Campus Melaten.

The involved researchers from the departments for electrical engineering, mechanical engineering, informatics, philosophy, economic sciences and communication science determine the necessary fun-damentals for a regional, flexible and reliable energy supply system. As part of this project, a demon-strator power plant will be built and operated to validate the technological developments.

The CWD’s contribution to KESS is the design of a wind park that covers the communal energy demand of an average annual consumption. An optimization tool for the placement of the turbine is developed, such that the annual energy output can be maximized while lowering the cost of energy. Furthermore, a flywheel energy storage is designed and simulated to enable an improvement of the power quality by smoothing of the power output of the wind park.

Integrated, available and peripheral energy supply systems based on conventional and renewable primary energies

The promoted ‘energy-transition’ causes a steadily rising percentage of renewable energies. Such a transition leads to a restructuring of the supply network, from a centralized power plants towards pe-ripheral energy supply units. These units allow to dimension the capacity with respect to local circum-stances. A challenge of this restructuring is the combination of existing systems and renewable sources, which are of volatile nature. In the future power grid an integrated solution of combined re-newable technologies and conventional, are a key requirement. Such a network structure combines the advantages of peripheral, renewable power supply with the predictability of entirely conventional energy supply systems. For this reason, renewable power conversion technologies, efficient energy storage, the supply of conventional residual power and a smart grid distribution are of particular im-portance for communal energy supply systems.
