Influence of Controller Tuning on Cascaded Flexibility Provision with Feedback Optimization
Irina Zettl, Florian Klein-Helmkamp, Florian Schmidtke +2
The coordination of a large number of flexibility-providing units across various grid layers requires innovative control concepts. This is needed, e.g., to allow active distributio…
Adaptive Tuning of Online Feedback Optimization for Process Control Applications
Marta Zagorowska, Lukas Ortmann, Giuseppe Belgioioso +1
Online Feedback Optimization leverages properties of optimization algorithms to develop controllers for systems with limited model availability, which is often the case in process…
Tuning a Cascaded Online Feedback Optimization Controller for Provision of Distributed Flexibility
Irina Zettl, Florian Klein-Helmkamp, Florian Schmidtke +2
Coordinating a high number of flexibility providing units (e.g. to provide ancillary services for the transmission system) across various grid layers requires new control concepts.…
Hierarchical Provision of Distribution Grid Flexibility with Online Feedback Optimization
Florian Klein-Helmkamp, Irina Zettl, Florian Schmidtke +2
Utilizing distribution grid flexibility for ancillary services requires the coordination and dispatch of requested active and reactive power to a large number of distributed energy…
Tuning and Testing an Online Feedback Optimization Controller to Provide Curative Distribution Grid Flexibility
Lukas Ortmann, Fabian Böhm, Florian Klein-Helmkamp +3
Due to more volatile generation, flexibility will become more important in transmission grids. One potential source of this flexibility can be distribution grids. A flexibility req…
Tuning of Online Feedback Optimization for setpoint tracking in centrifugal compressors
Marta Zagorowska, Lukas Ortmann, Alisa Rupenyan +2
Online Feedback Optimization (OFO) controllers steer a system to its optimal operating point by treating optimization algorithms as auxiliary dynamic systems. Implementation of OFO…
