Integrating high temperature heat pumps in paper drying processes as a step towards decarbonization

Afsaneh Norouzian, Sebastian Dickler, Isabel Kuperjans

This study evaluates industrial heat recovery by electrifying the paper drying process with high temperature heat pumps. A thermodynamic analysis is performed to evaluate key performance metrics, including coefficient of performance and energy consumption, for four configurations using different refrigerants. Additionally, a …

Towards high resolution, validated and open global wind power assessments

Edgar Ubaldo Peña-Sánchez, Philipp Dunkel, Heidi Heinrichs, Fritz B. Prinz et autres

Wind power is widely recognized as a key component of future net-zero energy systems. However, substantial variability among current wind resource and power simulations used for wind farm deployment limits the reliability of siting and system integration decisions. Therefore, we present a …

Regulation-aware optimization for bi-valent industrial processes

Jonathan Sejdija, Ralf Schemm, Marco Lauricella, Florian Maurer et autres

Abstract Industrial demand-side flexibility is essential for power systems with high shares of variable renewables, yet static grid fees and full load hours incentives can suppress flexible electrification by penalizing peaks and rewarding uniform consumption. This paper introduces an open, extensible, regulation-aware …

Model-Based Bikeability Indexing for Inter-City Comparisons to Evaluate Infrastructure and Level of Service for Cyclists

Jan Kellershohn, Sebastian Dickler, Christian Jungbluth

“Bikeability” is a measure of a city’s suitability for a bicycle-based lifestyle. Cities are striving to increase the number of cyclists in their traffic to decrease congestion and increase sustainability. Bikeability is therefore a relevant metric to measure a city’s progress towards …

Evaluating the Economic Impact of Local Power Purchase Agreements on Industrial Energy Costs: A Case Study of German Industries

Jonathan Sejdija, Florian Maurer, Ralf Schemm, Sebastian Dickler et autres

Power purchase agreements (PPAs) are increasingly adopted by industries to secure renewable energy while mitigating market price risks. This study evaluates the spatial and sectoral impacts of PPAs in Germany, focusing on wind energy. A scenario-based approach compares a market-based energy procurement …

Windenergieanlagen-Regelung: Ein Modell für die Zukunft

Sebastian Dickler, Thorben Wintermeyer‐Kallen, Thomas Konrad, Dirk Abel

Modellbasierte Prädiktive Regelungen bieten durch die zugrundeliegende Echtzeit-Optimierung Vorteile für moderne Windenergieanlagen, um gegenläufige Regelziele, wie etwa Leistungsmaximierung und Lastreduktion, unter der Berücksichtigung vorgegebener Betriebsgrenzen optimal zu erreichen. Der vorliegende Beitrag diskutiert die grundlegenden Herausforderungen der Windenergieanlagen-Regelung sowie die dazu genutzten Konzepte …

Full-scale field test of a model predictive control system for a 3 MW wind turbine

Sebastian Dickler, Thorben Wintermeyer‐Kallen, János Zierath, Reik Bockhahn et autres

Abstract Model predictive control (MPC) is a strong candidate for modern wind turbine control. While the design of model predictive wind turbine controllers in simulations has been extensively investigated in academic studies, the application of these controllers to real wind turbines reveals …

Weight-scheduling for linear time-variant model predictive wind turbine control toward field testing

Thorben Wintermeyer‐Kallen, Sebastian Dickler, János Zierath, Thomas Konrad et autres

Abstract Modern multi-megawatt wind turbines require powerful control algorithms which consider several control objectives at the same time and respect process constraints. Model predictive control (MPC) is a promising control method and has been a research topic for years. So far, very …

Repetitive Individual Pitch Control for Load Alleviation at Variable Rotor Speed

János Zierath, Sebastian Dickler, Thomas Konrad, Uwe Jassmann et autres

Abstract In recent years, wind turbines have been growing in size and became more lightweight and thus more flexible. Spatial variation in the wind speed results in asymmetrical blade loads, which include a periodic component increasing with growing wind turbine size. Asymmetrical …
