Hybrid Energy Systems

In the context of AIT’s Center for Energy, co-simulation has been identified as the most ap-propriate method to facilitate the detailed analysis of integrated energy systems. For this purpose, a combination of co-simulation-based approaches with hardware (controller-in-the-loop, hardware-in-the-loop) is utilised. These methods and technologies will support the development of energy management systems with exploitations streams in the industry, building and traffic sector.


Concept development

  • Design and operation of multi-carrier energy systems, with a focus on hybrid thermal-electrical networks
  • Integration of 4th generation district heating and cooling with electrical infrastructure

Methods development

  • Methodologies and workflows are required for the holistic assessment of hybrid energy systems, addressing both technical and economic aspects

Tool development

  • New tools for modeling, simulating, assessing and optimizing hybrid energy systems


Energy system integration and sector coupling

  • Addresses techno-economic aspects with focus on design and operation on system level
  • Has been identified as central strategic element in several research roadmaps (SET-Plan, „Grundsatzpapier zur Energie- und Klimapolitik“ of the Federation of Austrian Industries, etc.)
  • Becomes a new focus for R&D platforms (ETIP SNET, EERA JP ESI, etc.)

Transition towards hybrid energy systems poses practical challenges

  • Establishing AIT as a leader in supporting stakeholders from the public and the private sector
  • Services offered: transformation strategies, technology assessment, operational optimization, business model development

Complex energy systems

  • Tool development for the technical assessment of multi-domain energy systems (co-simulation)
  • Methods development for holistic assessment of integrated energy systems

District heating and cooling

  • Design and operation of 4th generation district heating networks
  • Assessment and planning of low-temperature networks (anergy grids)
  • Integration of renewable energy sources, waste heat and storages
