A Hybrid Submodular Optimization Approach to Controlled Islanding with Post-Disturbance Stability Guarantees
Luyao Niu, Dinuka Sahanbandu, Andrew Clark +1
Disturbances may create cascading failures in power systems and lead to widespread blackouts. Controlled islanding is an effective approach to mitigate cascading failures by partit…
A Reinforcement Learning Approach for Dynamic Information Flow Tracking Games for Detecting Advanced Persistent Threats
Dinuka Sahabandu, Shana Moothedath, Joey Allen +3
Advanced Persistent Threats (APTs) are stealthy attacks that threaten the security and privacy of sensitive information. Interactions of APTs with victim system introduce informati…
Controlled Islanding via Weak Submodularity
Zhipeng Liu, Andrew Clark, Linda Bushnell +2
Cascading failures typically occur following a large disturbance in power systems, such as tripping of a generating unit or a transmission line. Such failures can propagate and des…
Minimal Input Selection for Robust Control
Zhipeng Liu, Yao Long, Andrew Clark +4
This paper studies the problem of selecting a minimum-size set of input nodes to guarantee stability of a networked system in the presence of uncertainties and time delays. Current…
Input Selection for Performance and Controllability of Structured Linear Descriptor Systems
Andrew Clark, Basel Alomair, Linda Bushnell +1
A common approach to controlling complex networks is to directly control a subset of input nodes, which then controls the remaining nodes via network interactions. While techniques…
