Momentum-Accelerated Online Feedback Optimization for Power System Flexibility
Florian Klein-Helmkamp, Matthis Berger, Irina Zettl +1
Flexibility is increasingly gaining importance in modern power system operation. This paper presents a controller framework based on Online Feedback Optimization for real-time coor…
Dynamic Modeling, Analysis, and Validation of Dual-Port Grid-Forming Control for Hybrid AC/DC Systems
Irina Subotić, Dominic Groß, Alexander Winkens +3
This work investigates the transient and dynamical behavior of hybrid AC/DC systems using dual-port grid-forming (GFM) control. A generalized modeling framework for hybrid AC/DC ne…
Partially Observable Residual Reinforcement Learning for PV-Inverter-Based Voltage Control in Distribution Grids
Sarra Bouchkati, Ramil Sabirov, Steffen Kortmann +1
This paper introduces an efficient Residual Reinforcement Learning (RRL) framework for voltage control in active distribution grids. Voltage control remains a critical challenge in…
Stability and Performance of Online Feedback Optimization for Distribution Grid Flexibility
Florian Klein-Helmkamp, Tina Möllemann, Irina Zettl +1
The integration of distributed energy resources (DERs) into sub-transmission systems has enabled new opportunities for flexibility provision in ancillary services such as frequency…
Towards Safety and Security Testing of Cyberphysical Power Systems by Shape Validation
Alexander Geiger, Immanuel Hacker, Ömer Sen +1
The increasing complexity of cyberphysical power systems leads to larger attack surfaces to be exploited by malicious actors and a higher risk of faults through misconfiguration. W…
Graph-based Impact Analysis of Cyber-Attacks on Behind-the-Meter Infrastructure
Immanuel Hacker, Ömer Sen, Florian Klein-Helmkamp +1
Behind-the-Meter assets are getting more interconnected to realise new applications like flexible tariffs. Cyber-attacks on the resulting control infrastructure may impact a large…
Towards a Comprehensive Framework for Cyber-Incident Response Decision Support in Smart Grids
Omer Sen, Yanico Aust, Martin Neumuller +2
The modernization of power grid infrastructures necessitates the incorporation of decision support systems to effectively mitigate cybersecurity threats. This paper presents a comp…
