  • Published on September 2 2021
The transformation of the energy sector is a major challenge of the 21st century. At the Institute of Energy and Climate Research - Techno-economic Systems Analysis (IEK-3) we use large models to investigate the question, of which technologies energy systems need to be composed in order to become both, cost-efficient and environmnetally friendly.
Become part of our international research group and gain insights into the future of the energy sector. Not only you can use your expertise to create prognoses on the future capacity expansion, but also get an overview of different technologies and their synergies.

We are offering a

PhD Position - Impact of High-Frequency Demand and Supply Fluctuations on Energy System Design and Operation

Your Job:

Large energy system models optimize the size, allocation and operation of components based on simplified assumptions and finite time steps. Most of the models consider an hourly temporal resolution due to limited data availability and computational limitations imposed by the optimization problem. However, due to the coarse temporal resolution, it is not guaranteed that the optimized energy systems as proposed by the model would be operatable in reality. Therefore, the optimized models need to be tested for high-resolution time series, which steadily gain importance due to a growing share of renewable energy sources.

Contribute significantly to the reliability of cutting-edge energy system models by:

  • Collecting data and statistical features for various demand and supply time series and creating a data synthesizer for high-frequency fluctuations for different technologies and locations
  • Evaluating the quality of energy systems optimized based on coarse data by testing their operational feasibility for highly resolved data
  • Investigating the dynamical limitations of system components in the subhourly domain (e.g. ramping, minimum downtime, etc.)
  • Deriving statements on the reliability of current model predictions for future energy systems and quantifying their additional costs for guaranteeing their reliability based on your research findings
Your Profile:

  • A master`s or comparable degree in natural sciences, engineering, economics, mathematics, computer science or a related field of studies.
  • An interest for data science, data (de-)compression and the development of programming algorithms
  • Basic knowledge in computer-aided optimization and simulation
  • Fluent speaking and writing skills in English
  • A high degree of autonomy and commitment
  • A thorough and reliable working style
