Diverse fault types, fast reclosures, and complicated transient states after a fault event make
real-time fault location in power grids challenging. Existing localization techniques in this …

This paper focuses on joint cyber and physical attacks on power grids and presents methods
to retrieve the grid state information following such an attack. We consider a model where an …

This paper proposes a data-driven real-time event identification method based on the
measurements of Phasor Measurement Units (PMUs). The central idea is to characterize an …

Motivated by the recent cyber attack on the Ukrainian power grid, we study cyber attacks on
power grids that affect both the physical infrastructure and the data at the control center …

A quickest change detection (QCD) algorithm is proposed to address the problem of
detecting and identifying line outages in a power system. The statistics of electricity demand …

Real-time identification of successive events in power systems is crucial to avoid cascading
failures. Existing identification methods are mainly designed for single events and may not …

We study the problem of line failure detection following a cyber-physical attack. Since such
attacks can result in line trip**s (by remotely activating switches) as well as loss of …

Identifying a potentially large number of simultaneous line outages in power transmission
networks in real time is a computationally hard problem. This is because the number of …

Fast detection of power line outages is critical for maintaining the stable operation of the
power system. The aim of this article is to address the real time detection problem of multiple …

Recent attacks on power grids demonstrated their vulnerability to cyber and physical attacks.
To analyze this vulnerability, we study cyber-physical attacks that affect both the power grid …
