System Engineering Modelling

The system engineering modelling and analysis of physical processes, energy-technical components and even complex energy systems is a focal point of the work at ZAE Bayern, since in many areas of science numerical simulation has replaced theoretical and analytical considerations.

ZAE Bayern is in a position to incorporate the broad range of expertise available in the core topics - photovoltaics, energy storage and energy-optimised buildings - into its system engineering modelling. This allows us to predict the potential for innovative approaches and to investigate technical and economic feasibility. Simulations are based on a large number of commercial software products (e. g. CFD, TRNSYS, MATLAB/Simulink) and are supplemented by algorithms or customized simulation modules. With these tools, a deeper understanding of the system and an optimal interaction of material, component and system development is achieved. In addition, numerical simulation is used to optimize operating modes and individual processes.

Due to the experimental expertise in the different areas, the programs developed at ZAE Bayern can be validated and finally optimized. The interplay of basic knowledge, knowledge of the actual fields of application, experimental experience and the possibilities of system-technical modelling in an institute offers decisive advantages in the development and commercialisation of new energy technologies.

Fields of research

Energy concepts | municipalities

One focal point of the Energy Systems business area is the development of innovative municipal energy concepts for urban districts or area-wide supply areas. Different supply technologies are compared on the basis of the determined heat and cold demand structures as well as the energy saving potentials including efficient technology and renewable energy sources such as biomass, geothermal energy, solar energy and groundwater use.

Further processing points include future prognoses, technology assessments, the design of supply networks, the optimisation of energy centres as well as the economic and ecological evaluation of the overall system. Municipal energy concepts are drawn up at ZAE Bayern based on geographic information systems (GIS) in order to provide municipalities with a geo-referenced, redundant and updateable database that meets the requirements for data consistency and data integrity.

Projects

Solar local heating supply Speichersdorf

Various energy supply concepts with renewable energies were investigated for the Upper Franconian community of Speichersdorf. The main focus was on wood chips and thermal solar energy as energy sources. The achievable solar coverage rates are between 8 % and 40 %. Based on the energy demand survey carried out, taking into account the development of heat demand over time, eight different variants were developed and compared according to technical, economic and emission-related aspects, as well as a draft for a local heating network. The heat demand was presented on the basis of citizen surveys, photo documentation and specific heat demand variables from the project experience of ZAE and relevant literature. To determine the heat demand distribution, a GIS database was created in which each object was assigned energy and technical key figures. For the estimation of the future development of the energy demand, a reference scenario was created over a period of 30 years and the influences of boundary conditions (e.g. population development, energetic renovation rate) were investigated. The considered supply variants differ mainly in the design and combination of innovative, regenerative technologies such as solar thermal, long-term heat storage and absorption heat pumps.

The establishment of an operating company initiated the start of a regenerative local heat supply system in Speichersdorf.
