“Advanced modelling of E/UIPV systems from location to load”
Thursday, March 1st, 10:15 am in the PVcomB lecture hall (“Kleine Pause”, building 19.5), Schwarzschildstr. 3., Helmholtz-Zentrum Berlin, WCRC Berlin-Adlershof.
We report on an advanced modelling approach to accurately predict the energy yield of custom environment / urban integrated photovoltaic systems (E/UIPV). Several sub-models are here presented and their mutual interaction discussed. The flexibility of our software platform allows to exhaustively simulate custom horizons in combination with rigid/flexible PV modules and in presence of albedo component. In this respect, a modelling example predicts AC-side yield with < 1% error on annual basis with respect to actual data. In addition, our platform can also deal with coloured / bifacial modules and soiling losses for PV energy yield potential or performance prediction.

“The project PerduS – Improving the forecast and observations of Saharan dust induced reductions on photovoltaic power production in Germany”
Thursday, February 22st, 13:30 Uhr in the EE-IS lecture hall
(room 227, building 12.8), Kekuléstr. 5, Helmholtz-Zentrum Berlin, WCRC Berlin-Adlershof.
Due to illness of the speaker, we have to postpone the 2. seminar presentation (22nd Feb. , 13:30) to another date. This will be announced separately.
Already today Photovoltaic power production contributes with about 7.2% to the total electricity production in Germany. This needs to be constantly increased to achieve Germany's goal to produce 80% of the total electricity supply using renewable energy. The obvious dependency of PV power production on atmospheric conditions, induce a high demand on an accurate weather forecast to insure grid stability also in the future. A driving risk factor in forecasting PV power production in Germany, are Saharan dust clouds transported to Europe. The joint project PerduS which is a collaboration between the German weather service (DWD), the Karlsruhe Institute for Technology (KIT) and Meteocontrol, has its focus on the improvement of weather forecasts during such Saharan dust events. The online coupled NWP model ICON and the ART modules for the treatment of Aerosol and Reactive Trace gases form the base of the project PerduS. To achieve the project goals and to examine in detail, how strong the effect of Saharan dust on PV production is, accurate and extensively measurements of the Saharan dust in the atmosphere and of the ground reaching solar radiation is needed.
An important part of the project is to utilize the ground based measurement network of the DWD to observe dust clouds transported from the Saharan region to Germany. With a newly developed retrieval algorithm we estimate the effective aerosol optical depth (spectral) and aerosol size from ground based broadband measurements. In the NWP evaluation studies the measurements and retrieval results are used to evaluate the predicted Saharan dust AOD from the ICON-ART model. Further we want to close the circle of radiation measurements, the retrieval and the forecast results. Therefore the algorithm will be used under cloudless conditions as a radiative transfer model to calculate the solar radiation at the surface for the predicted atmospheric conditions. With our contribution to the workshop we show the potential of the retrieval algorithm to estimate the effective AOD from broadband measurements. Further we present results and analyses of several Saharan dust events which occurred since the start of the project.
