Abstract
With the increasing complexity and enhanced integration of distributed energy resources in the power system, situational awareness and decision support for power grid operators have become a significant challenge. Time-synchronized measurements at a high reporting rate by transmission Phasor Measurement Units (PMU) and distribution PMUs (also known as microPMU), opens up the possibility to develop data-driven applications for system reliability and resiliency.
In this dissertation, synchrophasor technology is analyzed, from metrology, communication, and applications perspective. The distribution system is known to be noisier than the transmission system and may have more harmonic content. A novel algorithm and architecture for DPMUs (Micro-PMUs) have been proposed in this dissertation including prototype implementation.
Due to the complex infrastructure associated with the syncrophasors, its measurements are prone to data quality issues. Therefore, data quality assessment at the point of use of the synchrophasor data has been studied and ensemble-based methods utilizing statistical and clustering techniques have been proposed to detect anomalies and optionally mitigate them. This dissertation develops the quality-aware monitoring and control applications utilizing the synchrophasor measurement. The quality-aware monitoring applications analyzed in this work include event detection, parameter estimation, oscillation monitoring, and failure diagnosis in the transmission protection system.
A quality-aware proactive control application to enhance the resiliency of the distribution grid has been developed. The algorithm has been tested and validated for the IEEE 123-node system and a real isolated microgrid system of a small town in Alaska. Results indicate a more resilient system under pro-active control schemes.
