Graph neural network-based tail-risk pricing for cyber insurance against cyber-physical attacks in power systems

Abstract Cyber insurance transfers the residual cyber risk that remains after technical controls are installed, yet conventional pricing models rarely condition losses on grid topology, operating state, communication dependencies, and physical consequences. We develop a graph neural network (GNN) framework for pricing...

Conformalized graph neural networks for distribution system state estimation with finite-sample-valid uncertainty quantification

Distribution system state estimation provides the network-wide voltage awareness required to operate active feeders, yet scarce real-time metering forces reliance on uncertain pseudo-measurements. This paper studies how to attach empirically auditable, finite-sample prediction intervals to learned network-wide voltage...
