A Multi-Agent Design for Power Distribution Systems Automation
… isolation and restoration in power distribution systems is presented. In proposed approach, when there is a fault in the Power Distribution System (PDS), MAS quickly isolates the fault and restores the service to fault-free zones. Hierarchical coordination strategy is introduced to manage the …

Fast power network detection of topology change locations using PMU measurements
… (PMUs). This scheme can be applied on reduced systems where parts of the network are not covered by PMU measurements. The scheme was tested during different outage events in the IEEE39-bus system. The obtained results validated the algorithm’s ability to detect and identify line outage events …

Software framework for protection relay testing
A software application is presented in this thesis that was designed to provide the framework for comprehensive automated testing of power system protection relays. This application was implemented using a model protection system that was designed to simulate actual relaying operations performed in …

A mixed-integer linear programming (MILP) model for dynamic coordinated signal optimization along a traffic corridor
In this thesis, we address urban traffic congestion, which imposes substantial economic and environmental costs while traditional infrastructure solutions remain increasingly infeasible due to financial constraints and induced demand. We develop a dynamic Mixed-Integer Linear Programming (MILP) …

Response Criterion Placement Modulates the Effects of Graded Alerting Systems on Human Performance and Learning in a Target Detection Task
Human operators can perform better with the use of an automated diagnostic aid than without the use of an aid in a signal detection task. This experiment aimed to determine whether any differences existed among graded aids—automated diagnostic aids that use a scale of confidence levels reflecting a …
