Engineering Trustworthy Agentic AI for Critical Systems

Omar Al-Refai, Ibrahim Shahbaz, Adam Ali Husseinat, Michael Mandulak, Jaewon Kim, Eman Hammad

Agentic artificial intelligence systems, capable of autonomous perception, planning, tool use, and multi-step action, are increasingly proposed for critical engineering domains where decisions carry physical, operational, or economic consequences. This survey addresses a gap in c…

Causal--Structural Dynamic Graph Learning for Online Transient Stability Trajectory Prediction in Power Systems

Ibrahim Shahbaz, Omar Al-Refai, Isaac Lagoy, Ahmad Al-Khateeb, Sathvik Sankaranarayanan, Eman Hammad

Power systems consist of dynamically coupled generators, motivating the use of Graph Neural Networks (GNNs) for online transient stability prediction. Traditional GNN frameworks are often constrained by fixed admittance-based topologies that fail to capture state-dependent coupli…

Inertia-Informed Federated Learning Control Framework for Distributed Smart Grid Resilience

Ibrahim Shahbaz, Omar Al-Refai, Eman Hammad

Resilient-by-design smart grid control demands frameworks capable of maintaining stability under physical disturbances and communication failures, without reliance on centralized coordination. While Centralized Training Decentralized Execution (CTDE) enables a learning-based cont…

Federated Physics-Grounded Reinforcement Learning for Distributed Stability Control in Smart Grids

Omar Al-Refai, Ibrahim Shahbaz, Adam Ali Husseinat, Eman Hammad

Transient stability control in smart grids requires rapid post-fault damping of generator frequency and rotor angle deviations to prevent cascading failures. This paper proposes FedPPO-PG, a Federated Multi-Agent Proximal Policy Optimization framework with Physics-Grounded neighb…
