In the face of increasing natural disasters and an aging grid, utilities need to optimally
choose investments to the existing infrastructure to promote resiliency. This paper presents a …

The ground truth for cascading failure in power system can only be obtained through a
detailed dynamic model involving nonlinear differential and algebraic equations whose …

A challenging problem facing AC-Quasi-Steady-State (AC-QSS) cascading failure models of
power system is the divergence issue primarily stemming from voltage collapse phenomena …

We propose a two-stage scenario-based stochastic optimization problem to determine
investments that enhance power system resilience. The proposed optimization problem …

The goal of this work is to identify critical nodes in a bulk electric system for grid resilience to
a specified threat. We present a cascading outage framework and an analytical framework …

Cascading failure in the power system is a low-probability-high-risk event. It has significantly
negative impact on the economy and society in general. Therefore, it is necessary to …
