Three-Phase Linear State Estimation with Phasor Measurements
… Unit (PMU) to directly measure the system state and the increasing implementation of PMUs across the electric power industry, a natural expansion of state estimation techniques would be one that employed the exclusive use of PMU data. Dominion Virginia Power and the Department of Energy …

The optimal placement of phasor measurement units and their effects on state estimation
… full observability, 2. conventional, hybrid and linear state estimation techniques to incorporate and utilize PMU measurement data to perform state estimation and to study the effects that differing PMU placement positions have on the accuracy of the resultant state estimator solution.

Synchrophasor-Only Dynamic State Estimation & Data Conditioning
… the quality of the data stream which leaves the linear estimator is crucial to establishing it as the front end of an EMS system and network applications which employ synchrophasor data. This can be accomplished using a two-fold solution: the pre-processing of phasor data before it arrives at the …

State feedback control with time delay
… and active schemes. We introduce the problem of state feedback control and provide the classical solution in the form of Ackermann formula. We then identify the limitations of the classical approach and present the more elegant solution of partial pole assignment without spillover. We highlight …

PMU-Based Applications for Improved Monitoring and Protection of Power Systems
… system operation can be realized. A PMU-only linear state estimator is intrinsically superior to its predecessors with respect to performance and reliability. However, ensuring quality of the data stream that leaves this estimator is crucial. A methodology for performing synchrophasor data …

Nonlinear Observers for Aircraft Maneuvering in Wind
… operational limits. This motivates indirect wind estimation methods that infer wind from aircraft motion. However, typical model-based estimators lack rigorous stability guarantees across the full flight envelope --- a major limitation for safety-critical aerospace applications. This dissertation …
