Determining Intra-hour Solar Irradiance Variability with a Low-cost Solar Logger Network
2014 (English)In: Proceedings of 4th International Workshop on Integration of Solar Power into Power Systems, 2014Conference paper (Other academic)
The study of solar irradiance is of vital importance in order to quantify the fluctuation that the transmission system needs to handle in case of large scale solar power integration. In this paper, early results from a low-cost solar irradiance logger network are presented. The main advantages of the solar logger are its low cost (~$50) and mobility. Our results confirm previous models of the station pair correlation of clear sky index step changes, with the modification that the isotropic correlation appears to decrease exponentially as a function of Δt-1/2 rather than Δt-1 as has been proposed earlier.
