Failure prevention and restoration in power systems

In typical power system operations, failures, e.g., caused by degradation, may result in service interruption and loss of power supply. Furthermore, low-occurrence-probability but high-impact extreme events, e.g., natural disasters and cyber-attacks, may also damage the power grid. This thesis aims to develop innovative strategies for handling...

Influence of Measurement Uncertainty on Parameter Estimation and Fault Location for Transmission Lines

Fault location algorithms for transmission lines use the parameters of the transmission line to locate faults after the faults have occurred along the line. Although these parameters can be estimated by the phasor measurement units (PMUs) at the terminal(s) of the transmission line continuously, the uncertainty in the measurements will give...
