Forecasting day-ahead electricity prices: A comparison of time series and neural network models taking external regressors into account
No full textThe amount of renewable energies in electricity production has increased significantly in the last decade, resulting in more variability of the day-ahead electricity spot price. The Electricity Price Forecast (EPF) has to adapt to the new situation by applying flexible models. However, the numerous available forecasting methods differ widely, with no distinct candidate offering the best solution. Against this background, we conduct a comparative study of four different approaches to forecasting the German day-ahead electricity spot price. In addition to the prominent Seasonal Integrated Auto-Regressive Moving Average model ((S)ARIMA(X)) and the Long-Short Term Memory (LSTM) neural network models, we employ a Convolutional Neural Network LSTM (CNN-LSTM) and an extended two-stage multivariate Vector Auto-Regressive model (VAR) approach as hybrid models. For better performance, we include common external influences such as the consumer load, fuel and CO2 emission prices, average solar radiation and wind speed in our analysis. We analyse hourly data for twelve samples from October 2017 to September 2018. Each model is implemented to deliver price forecasts at three horizons, i.e., one day, seven days and thirty days ahead. While the LSTM model achieves the best forecasting performance on average, the two-stage VAR follows closely behind and performs exceedingly well for shorter prediction horizons. Further, we provide evidence that a combination of both forecasting methods outperforms each of the single models. This indicates that combining advanced methods could lead to further improvements in electricity spot price forecasts.10

Fabian lernt "schwimmen"
No full textMit der Absicht, eine Brücke zwischen deutschsprachiger Literatur und Humanistischer Psychologie zu konstruieren, geht die vorliegende Arbeit der Frage nach, ob es möglich ist, eine fiktive Person, die vor dem Hintergrund der Weltwirtschaftskrise von 1929 im Verlauf einer Romanhandlung arbeitslos geworden ist, durch Anwendung einer humanistischen Therapieform wieder in die Arbeitswelt zu integrieren. Die fiktive Person ist Jakob Fabian aus Erich Kästners neusachlichem Zeitroman Fabian. Die Geschichte eines Moralisten, erschienen 1931, und bei der humanistischen Therapieform handelt es sich um den „Klientenzentrierten Ansatz“ nach Carl Rogers. Die zentrale Forschungsfrage wird in zwei großen Schritten beantwortet: Im ersten Schritt werden themenrelevante Aspekte hinsichtlich Roman, Autor sowie Protagonist erläutert und analysiert, bis die Romanfigur Jakob Fabian zum Klienten Jakob Fabian wird und ein Anamnesebericht über diesen vorliegt. Basierend darauf, werden mit dem Ergebnis der beruflichen Rehabilitation im zweiten Schritt klientenzentriert-orientierte Therapiegespräche in einem realen Setting durchgeführt und transkribiert. Das Konzept dieser Arbeit kann als Modell auf weitere Arbeitslosenromane der Weimarer Republik angewendet werden. Zusätzlich besteht auch die Möglichkeit, das Setting an Beratungssituationen anzupassen.With the intention of constructing a bridge between German literature and “Humanistic Psychology”, the present thesis analyses the question, whether it is possible to reintegrate a fictitious man into the working environment by applying a humanistic type of therapy, who, against the background of the world economic crisis of 1929, in the course of a novel's plot has lost his job. Jakob Fabian is the fictional character in Erich Kästner’s new objectivity period novel Fabian. The story of a moralist, pub-lished in 1931, and the humanistic therapeutic method is the Rogerian Client-centered approach. The core issue is answered in two major steps: In the first step, issue-specific aspects regarding novel, author and protagonist are explained and analysed until the fictional character Jakob Fabian turns into the client Jakob Fabian and until an anamnesis report is available. Based on this, with the outcome of vocational rehabilitation in the second step, client-centred-oriented therapy sessions are conducted in a real setting and transcribed. The concept of this work can also be used as a model for other novels about unemployment during the Weimar Republic. In addition, it is also possible to adjust the setting of advisory situations
