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.enPhotovoltaikPhotovoltaische Module und KraftwerkeSolare Einstrahlungs- und Leistungsprognosenmonitoringpyranometercontrolradiationshading621697conference paper
