Ghana suffers from frequent power outages, which can be compensated by off-grid energy solutions. Photovoltaic-hybrid systems become more and important for rural electrification due to their potential offer a clean cost-effective supply. However, uncertainties related the prediction of electrical loads solar irradiance result in inefficient system control lead an unstable electricity supply, is vital high reliability required applications within health sector. Model predictive (MPC)...
Abstract. This work proposes a novel approach for probabilistic end-to-end all-sky imager-based nowcasting with horizons of up to 30 min using an ImageNet pre-trained deep neural network. The method involves two-stage approach. First, backbone model is trained estimate the irradiance from imager (ASI) images. then extended and retrained on image parameter sequences forecasting. An open access data set used training evaluation. We investigated impact simultaneously considering global...

<p>The accurate forecasting of solar radiation plays an important role for predictive control applications energy systems with a high share photovoltaic (PV) energy. Especially off-grid microgrid using can benefit from forecasts temporal resolution to address sudden fluctuations PV-power. However, cloud formation processes and movements are subject ongoing research. For now-casting applications, all-sky-imagers (ASI) used offer appropriate aforementioned application. Recent...
In diesem Paper wird ein Modell eines Photovoltaik(PV)-Diesel-Hybrid-Systems aufgebaut. Dieses System besitzt neben einer PV-Anlage einen Batteriespeicher und ist an das offentliche Stromnetz angeschlossen. Bei einem Ausfall aller drei Energiequellen stellt Dieselgenerator die Stromversorgung sicher. Mit Hilfe des erstellten Modells der Einfluss unterschiedlichen Jahreszeiten Wetterbedingungen auf den PV-Ertrag gesamte im Zeitraum von Februar 2016 bis 2017 untersucht. Die Messdaten dafur...
