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 these two kinds of failures in power grids. In particular, we develop preventive maintenance strategies, a pre-disaster electrical vehicle charging control strategy, an accurate fault location algorithm, and an unmanned aerial vehicles routing strategy for post-disaster distribution networks....
