Quickest change detection with applications to line outage detection
… we focus on applications of quickest change detection (QCD) theory in the problem of line outage detection and identification. We start by discussing fundamental results of sequential hypothesis testing and QCD, and by proposing an algorithm for the QCD setting under transient dynamics. …

Real-time power system topology change detection and identification
This thesis proposes a framework for detection and identification of system topological changes in near real-time that utilizes the statistical properties of electricity generation and demand, which are assumed to be known. Instead of relying on offline models as with traditional methods, the …

Line and Generator Outage Identification using Synchrophasor Measurements
Identification of outages in power systems is crucial to raise situational awareness and prevent cascading failures. As a result of wide adoption of phasor measurement units (PMUs), synchronized measurements with high temporal resolution provide new opportunities for event detection and …

Machine learning-based intrusion detection system in advanced metering infrastructure
… attacks, many authors recommend using Intrusion Detection Systems (IDSs). An IDS use a classifier to distinguish between known and unknown threats. It is challenging to choose the proper IDS category, however, as no single category can accurately identify all types of attacks. A smart grid's …

Measurement-based tools for power system monitoring and operations
… method is proposed to detect and identify line outages using quickest change detection algorithms. The proposed scheme is evaluated by its average detection delay and the probability that the wrong line outage is identified. In order provide support for the tools proposed in this thesis, the …
