Abstract/Summary:

---

Grid operators have to apply upscaling techniques to estimate the total power feed-in by PV systems in their control areas. In order to improve the real-time upscaling of PV power production in the control area of the German transmission system operator TransnetBW we set up a network of 40 solar irradiance measurement stations in the TransnetBW control area in Southern Germany. The measurement stations consist of a pyranometer, measuring global horizontal irradiance, and three silicon cells oriented east, south, and west with tilt angles of 25°. They measure irradiance in minute resolution and transfer the data in near real time. In order to ensure a good quality of our data we have developed a new quality control scheme exploiting the sensors with different orientations. Here we focus on our approaches for detection of horizons profiles and orientations by learning from measurements.
