- Daniel Selvaratnam, Post-doc, Division of Decision and Control Systems
- Kamil Hassan, PhD student, Division of Decision and Control Systems
The AIT host group was comprised of:
- Thomas Strasser (ERIGrid2.0 Co-ordinator)
- Filip Pröstl-Andrén (Technical Coordination)
- Diego Cifelli
- Denis Vettoretti
- Elisabeth Mrakotsky-Kolm (Administration)
In this work, the voltage regulation problem for inverter-interfaced power distribution networks was considered under the framework of ‘resilience’. To make things clear, the formal definition of a resilient system can be seen as a system which fully responds to durability and recoverability.
The group investigated the voltage regulation problem for inverter-interfaced power distribution networks under adversarial power injection attacks. Furthermore, the problem was explored under the framework of resilience, where, in addition to voltage stability under nominal conditions, formal guarantees of finite-time recovery from unbounded adversary events were also pursued for the given power inverter network. To that end, a finite-time robust control barrier function (FRCBF)-based resilient control design paradigm was proposed. Then, to test the theoretical claims for the proposed resilient controller, hardware-in-the-loop (HIL) simulation case studies were conducted under the ‘worst-case’ power injection attack scenar-io. The simulation results showcased the efficacy of the proposed resilient control approach and the voltage regulation problem for the considered power inverter network was addressed to satisfaction. For future work, it is aimed to investigate the effectiveness of the proposed resilient controller for larger networks, to test its scalability, and also consider additional fault/attack scenarios that are more commonly encountered.
