Master Thesis F M X - Deep Learning-Based Cloud-Base Height Retrieval

The Institute of Solar Research develops innovative technologies for the utilisation of solar energy. The focus is on electricity generation and the provision of heat and fuels. The primary goal is to use solar energy to contribute to the heat transition and a reduction in fossil fuels.

What To Expect

You will work on AI-based, spatially resolved short-term solar irradiance forecasts that aim to enable the integration of PV power plants into the balancing energy market. This involves using data from high-resolution all-sky imagers operated by DLR near Oldenburg and in Almería, which capture cloud dynamics that drive PV power variability. Your main focus will be on developing machine-learning methods to improve cloud-base-height estimation, as existing models still show significant errors.

You will be part of a diverse and motivated team working on energy-transition topics and contributing to climate protection. Close collaboration with supervisors and colleagues will support you in exchanging ideas and solving challenges. You will gain hands-on experience in machine learning, software development, automated testing, version control and modern image-processing technologies. A particular highlight of the project is the opportunity to work in Almería, one of the sunniest locations in Europe.
