Reference number: 2021D-051


In order to address the climate change and achieve the internationally set climate targets, the energy supply will have to undergo major changes in the coming decades. What will the energy mix look like after the phasing out of nuclear power and coal, and the expansion of renewable energies? Which technologies will have to be introduced or further developed? What consequences will result from the change in transportation? What could a climate-neutral energy supply look like that makes economic sense and at the same time offers sufficient security of supply?
In order to be able to answer these and other questions scientifically, numerous models are being developed at the Institute of Energy and Climate Research - Techno-economic Systems Analysis (IEK-3), in the research field of energy system analysis, with which energy systems can be represented and examined. Energy system analysis faces the challenge that a large number of complex models have been developed in the past, which are very heterogeneous in their objectives, methods and level of detail. It is therefore becoming increasingly difficult to identify the models best suited to answer a specific research ques-tion and to understand their respective differences and specificities.

We are offering a

PhD position - Automated orchestration of distributed energy system model workflows

Your Job:

First, you will design a semantic framework for the description and categorization of energy system models and their underlying methods. Based on this framework, you will describe the characteristics of selected models in the context of a method and soft-ware catalog. To ensure the sustainability and continuous extensibility of this catalog, it will be embedded in the digital structures of the Open Research Knowledge Graph (ORKG).
On the basis of ontology-based interface descriptions, you will identify suitable model workflows resulting from model combinations in this context in addition to individual models. In order to support the selection of a workflow, you will develop technical and content-related comparison criteria as well as methods for their measurement. Finally, the orchestration and computation of cross-platform and distributed workflows will be automated as far as possible.

  • Conception of a semantic framework for the description and categorization of energy system models and their underlying methods
  • Development of a method and software catalog within the ORKG
  • Use of ontologies to identify models and methods suitable for answering scientific questions
  • Definition of content-related and technical criteria for the comparison of models and methods and development of procedures for their measurement
  • Automation of model workflows using state-of-the-art software container technologies

Your Profile:

  • Masters degree in computer science, information systems, engineering, mathematics or a comparable course of study, which you have completed with very good results
  • Interest in energy technology and energy management issues
  • Experience in modeling, simulation and optimization desirable
  • Experience with ontologies, knowledge graphs or the Semantic Web desirable
  • Good programming skills (preferably in Python)
  • Independent and analytical working style within a project team

Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change!

We offer ideal conditions for you to complete your doctoral degree:

  • Excellent scientific and technical infrastructure - optimal conditions for a success-ful and timely doctorate
  • A highly motivated and international working group within one of the largest re-search institutions in Europe
  • Participation in high-ranking organizations such as the International Energy Agen-cy
  • Participation in project meetings and international conferences
  • Further development of your personal strengths, e.g. through an extensive range of training courses and participation in interdisciplinary seminars including a certifi-cate
  • Continuous professional supervision by your scientific supervisor
  • Flexible working hours and the possibility to work from home
  • Special support for international employees, e.g. through our International Advisory


  • Usually a contract for a period of 3 years in the context of a PhD at the RWTH Aachen under support of Dr. Patrick Kuckertz
  • Remuneration analogous to pay group 13 (75%) of the public sector collective agreement (TVöD-Bund) and additionally 60 % of a monthly salary as special payment („Christmas bonus“).
