"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

Your mission:

Nowcasting systems based on upwards-facing all-sky imagers can provide spatially resolved DNI maps. Classification schemes are used to analyse the shadow patterns as well as irradiance intensity and categorize the current conditions into temporal and spatial variability classes. It has been proven through the in-house dynamic solar field simulation tool, the Virtual Solar Field, that solar field controllers can be tuned to increase the energy yield of the power plants during transient processes. The nowcasting systems also offer short-term forecasts for the solar irradiance maps of up-to 15 minutes. Using this additional information the operators have more potential to further increase their yield by providing proactive control actions to optimize the operation.

Within the scope of the proposed thesis, model-predictive control strategies will be developed to use solar irradiance forecasts. The controllers will be able to take the uncertainties within the forecasts into consideration when deciding the control actions. The new controllers are to be implemented within the in-house developed simulation software for line-focus systems, the Virtual Solar Field.

Your qualifications:

  • solid knowledge in simulation techniques and control engineering
  • solid knowledge of Matlab and C++ programming
  • preferably good knowledge in fluid dynamics and thermodynamics
  • knowledge in concentrating solar power is advantageous

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy puts great value on a healthy work-life balance as well as equal opportunities for men and women. Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
