Sustainable energy systems for urban quarters and cities

The “Sonnenschiff” is the service centre for the solar settlement in Freiburg – and the first commercial premises to be designed as a plus-energy building.

System Integration - Electricity, Heat, Gas

Our Fields of Work comprise:

Operation Management and Optimization of Energy Supply Systems

Smart Energy Cities, District Concepts and Heat Grids

Power Distribution Grids and Operating Equipment

The transformation of our energy system into a carbon-free energy supply presents us with a great challenge. By combining the electricity, gas and the heat sector, different storage systems (thermal, electric, hydrogen / gas) can be used to compensate for fluctuations in the supply. In this business area, technical questions on the systems level are investigated, e.g., the integration of PV battery systems, the power production from electric-heat driven CHP systems or also the thermal conversion of surplus electricity.

Operation management plays a central role here, since predictive management is of primary importance for storage systems. Spot market prices and weather forecasts are also considered for the proactive management. System integration is also a central focus for urban quarters and Smart Energy Cities, which require a comprehensive optimization of the supply structure and the mobility concept in the urban space. By modeling and simulating energy systems and grids, the energy flows can be analyzed. Questions about the integration of new decentralized grid technologies can be answered.

Our service units related to the topic of System Integration - Electricity, Heat, Gas:

  • Power quality measurements and grid monitoring:
    Measure grid utilization, voltages and harmonics as well as evaluate according to Standards EN 50 160 or EN61000 Series
  • Controller validations:
    Laboratory and field validations of reactive and active power controllers, test of parameter settings on the grid operator side
  • Creation visualizations of web based status
    Visualizations of  transformer load, voltage, current and power measurements integrated into a schematic grid topology or GIS data
  • Service Lab Smart Energy
    The Service Lab Smart Energy at Fraunhofer ISE is a highly modern test laboratory. It has a full range of equipment which includes renewable and efficient suppliers and storage (both electric and thermal) ready for single and multiple-family homes of the future. By visualizing and interconnecting the thermal and electric energy flows, we offer our clients a platform for the analysis, evaluation and development of Smart Homes and Smart Grid technologies on the distribution grid level
