A database of 4,687 points was built and analyzed with multivariate adaptive regression spline modelling, partial dependence plots, and linear regression. The marginal impacts on skill score of ten factors were quantified. The analysis shows the non-linearity and complex interaction between variables in the database. Forecast horizon has a central impact and dominates other factors' impacts. Therefore, the analysis of solar forecasts should be done separately for each horizon. Climate zone variables have statistically significant correlation with skill score. Regarding inputs, historical data and spatial temporal information are highly helpful. For intra-day, sky and satellite images show the most importance. For day-ahead, numerical weather predictions and locally measured meteorological data are very efficient. All forecast models were compared. Ensemble-hybrid models achieve the most accurate forecasts for all horizons. Hybrid models show superiority for intra-hour while image-based methods are the most efficient for intra-day forecasts. More training data can enhance skill score. However, over-fitting is observed when there is too much training data (longer than 2000 days). There has been a substantial improvement in solar forecast accuracy, especially in recent years. More improvement is observed for intra-hour and intra-day than day-ahead forecasts. By controlling for the key differences between forecasts, including location variables, our findings can be applied globally.}, language = {en} } @misc{JalboutGengeMuesgens, author = {Jalbout, Eddy and Genge, Lucien and M{\"u}sgens, Felix}, title = {H2Europe: an analysis of long-term hydrogen import-potentials from the MENA region}, series = {18th International Conference on the European Energy Market (EEM), 13-15 September 2022, Ljubljana, Slovenia}, journal = {18th International Conference on the European Energy Market (EEM), 13-15 September 2022, Ljubljana, Slovenia}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-6654-0896-7}, issn = {2165-4093}, doi = {10.1109/EEM54602.2022.9921055}, pages = {1 -- 7}, abstract = {Our paper assesses the economic viability of green hydrogen exports from the middle east and north Africa to the EU in the long-term (for the year 2050). For this purpose, we simulate a techno-economic hydrogen supply chain based on generation from renewable energy sources. The chain of production, conversion, and transportation costs, in combination with potentials, yields a merit order of hydrogen supply. The paper focuses on one low-cost option for imports from the middle east and north Africa region. In addition, it provides a classification of additional options. We find that due to proximity, retrofitting and potentially even installing new pipelines from Morocco, Algeria and Tunisia could provide nearly half the expected European demand of 60 million tons p.a. by 2050. Based on our assumptions, the costs would be around 2 €/kgH 2 .}, language = {en} } @misc{RiepinSgarciuBerneckeretal., author = {Riepin, Iegor and Sgarciu, Smaranda and Bernecker, Maximilian and M{\"o}bius, Thomas and M{\"u}sgens, Felix}, title = {Grok It and Use It: Teaching Energy Systems Modeling}, series = {SSRN eLibrary}, journal = {SSRN eLibrary}, issn = {1556-5068}, doi = {10.2139/ssrn.4320978}, abstract = {This article details our experience developing and teaching an "Energy Systems Modeling" course, which sought to introduce graduate-level students to operations research, energy economics, and system modeling using the General Algebraic Modeling System (GAMS).

However, uncertainties in supply and demand make such predictions challenging. We propose a hybrid model that combines a techno-economic energy system model with stochastic models to address this challenge. The techno-economic model in our hybrid approach provides a deep understanding of the market. It captures the underlying factors and their impacts on electricity prices, which is impossible with statistical models alone. The statistical models incorporate non-techno-economic aspects, such as the expectations and speculative behaviour of market participants, through the interpretation of prices. The hybrid model generates both conventional point predictions and probabilistic forecasts, providing a comprehensive understanding of the market landscape. Probabilistic forecasts are particularly valuable because they account for market uncertainty, facilitating informed decision-making and risk management. Our model delivers state-of-the-art results, helping market participants to make informed decisions and operate their systems more efficiently.}, language = {en} } @misc{MuesgensOckenfels, author = {M{\"u}sgens, Felix and Ockenfels, Axel}, title = {Design von Informationsfeedback in Regelenergiem{\"a}rkten}, series = {Zeitschrift f{\"u}r Energiewirtschaft}, volume = {35}, journal = {Zeitschrift f{\"u}r Energiewirtschaft}, number = {4}, issn = {1866-2765}, doi = {10.1007/s12398-011-0062-0}, pages = {249 -- 256}, abstract = {Auf vielen kontinentaleurop{\"a}ischen Energiem{\"a}rkten werden derzeit die Regeln f{\"u}r das Feedback auf Regelenergiem{\"a}rkten diskutiert: welche Informationen zu vergangenen Auktionen sollen wann ver{\"o}ffentlicht werden?
