For solar power stations, the constant alternation of sun and clouds result in a continuous disruption of the balance between power supply and demand. Short-term forecasts are therefore used to restore this balance and ensure a constant electricity supply. In the project WobaS-A, a cloud camera-based forecasting system realised in the previous project WobaS is being improved and prepared for use in various power stations with parabolic fluted reflectors, solar towers and photovoltaics.
In addition, the CSP-FoSyS forecasting system developed by DLR and TSK Flagsol specially for concentrating solar power stations is being expanded for global radiation forecasts, making it usable by photovoltaics installations. The integrating potential of the ultra-short-term and short-term forecasting systems Wobas and FoSyS is being investigated.
The goal of the project is to prepare for the market introduction of the forecasting system in target areas of application by expanding the system and carrying out functional verifications. This should foster increased interest in this next generation of system control technology. The results are initially aimed at individual solar installations but should also be expanded to large-scale power plants.
The work of the researchers at the Institute of Networked Energy Systems is focused on developing methods for expanding the satellite-based forecasting system for larger PV power stations.
