Exposing the Invisible: Detecting Stealthy Parameter-Based Cyber-Attacks on Inverter Synchronization Loops
Zaint A. Alexakis, Michal M. Drewniak, Charalambos Konstantinou
The increasing integration of Internet-of-Things (IoT) technologies for monitoring and control of inverter-based resources (IBRs) has expanded the attack surface, enabling stealthy…
The Cheap Hours Don't Stay Cheap: Price-Chasing Data Centers Reshape Grids and Markets
Shijie Pan, Zaint A. Alexakis, Charalambos Konstantinou
Data centers unsettle the paradigm of location-bound electricity demand: computing workloads can migrate across sites and hours, whereas facilities and grid connections remain fixe…
A Cyber Insurance Policy for Hedging Against Load-Altering Attacks and Extreme Load Variations in Distribution Grids
Shijie Pan, Zaint A. Alexakis, S Subhash Lakshminarayana +1
Uncertainties in renewable energy resources (RES) and load variations can lead to elevated system operational costs. Moreover, the emergence of large-scale distributed threats, suc…
Smooth Rate Limiter Model for Power System Stability Analysis and Control
Zaint A. Alexakis, Panos C. Papageorgiou, Antonio T. Alexandridis +2
The letter proposes a smooth Rate Limiter (RL) model for power system stability analysis and control. The proposed model enables the effects of derivative bounds to be incorporated…
