The Moses Lab – Power Quality and Resilience Laboratory, is affiliated with the School of Electrical and Computer Engineering (ECE) at the University of Oklahoma
Power quality and resilience are the unifying, intertwining themes of this group. Power quality encompasses a broad spectrum of issues—including electromagnetic transients, disturbances, oscillations, faults, bifurcations, and complex nonlinear and chaotic dynamics—that critically influence the resilience and reliability of power systems. These phenomena span from localized component-level challenges to large-scale system-level interactions. As society increasingly adopts converter-based technologies, the occurrence and complexity of power quality issues are growing, further compounded by natural hazards and disasters that threaten overall grid resilience.
The group’s goal is to carry out cutting-edge research in:
- insulation condition monitoring and diagnostics for electrical apparatus operating in distorted electrical systems
- detection, classification and fault mitigation of power system disturbances considering volatile inverter-based sustainable energy technologies
- enhancing resiliency analytical frameworks for better characterization of high impact grid disruptions
- untangling nonlinear, dynamical and chaotic electromagnetic transient phenomena interacting with electric machinery and switched-mode devices
- understanding the complex interactions and physics in low-inertia energy grids including nano-micro-grids in terrestrial networks and marine vessels
The research conducted by this group targets practical solutions across a range of industries, including utility networks, naval and marine shipbuilding, and other critical sectors. Our contributions have advanced predictive modeling and system protection strategies by accounting for nonlinear dynamics and chaotic behavior in electrical networks. We have also supported the development of next-generation naval shipboard power systems and pioneered new approaches for quantifying power network resiliency.
This group has developed a suite of tools enabling novel experimentation and theoretical studies with close collaboration with industries nationwide. The lab serves as a training ground for equipping undergraduate and graduate students with specialist knowledge in complex electromagnetic disturbance phenomena and dynamical behavior relevant to 21st century power systems. Our vision is to impart unique skills, uncover new understandings and fill knowledge gaps while supporting a much needed sustainable workforce in power engineering industries within the State of Oklahoma and worldwide.
