The Institute for Solar Research develops innovative technologies for the use of solar energy. The focus is on electricity generation and the provision of heat and fuels. The primary goal is to contribute to the energy and heat transition and to a reduction in fossil fuels with the help of solar energy.
The Solar Energy Meteorology Working Group develops methods for deriving measurements and very short‑term forecasts of solar radiation from image information provided by cloud cameras, thereby supporting the efficient and grid‑friendly operation of photovoltaic power plants.
This thesis aims to further develop a method for determining diffuse solar radiation, which uses the image from a cloud camera and the measurement from a pyranometer (global radiation) as input data. The measurement uses a radiometric camera model and a multimodal machine learning model based on image and tabular data. Currently, images with low dynamic range are to be ...
