Measurement-based tools for power system monitoring and operations
This thesis proposes several online power system monitoring and operations tools that leverage real-time measurements with little or no reliance on models obtained offline. Instead of relying on offline models, which can be grossly inaccurate, as in conventional power system monitoring and …

Placing Monitoring Devices in Electric Power Networks Modeled by Block Graphs.
<p>The problem of monitoring an electric power system by placing as few measurement devices in the system as possible is closely related to the well known vertex covering and dominating set problems in graph theory. A set <em>S</em> of vertices is defined to be a power dominating set of a graphs if …

On-line Calibration of Instrument Transformers Using Synchrophasor Measurements
The world of power systems is ever changing; ever evolving. One such evolution was the advent of Phasor Measurement Units (PMUs). With the introduction of PMUs in the field, power system monitoring and control changed for the better. Innovative and efficient algorithms that used synchrophasors came …
