Participants could review and adopt complete CUSP course materials in power systems, power electronics, electric drives, and finite-element machine design.

Providing Hands-on Experience in Electric Power Engineering Education

This online workshop demonstrated hands-on laboratories for electric-power education at undergraduate and graduate levels. Faculty presented laboratory platforms for advanced power electronics, electric drives and control, power systems using PSS®E and Python, climate-crisis solutions, and sustainable electricity, followed by discussion of community- and technical-college certificate pathways.

Analysis, Simulation, and Implementation of Vector Control: An Extremely Low-Cost Laboratory

This tutorial provides an overview of vector control for induction motors and PMAC motors, starting with the fundamentals of DC motor operation and closed-loop control. These concepts are then extended to AC drives using dq-transformation. All concepts are validated through numerical simulation using Sciamble Workbench (free-of-cost, ONR-funded) and demonstrated in real time using a low-cost electric drives lab kit developed at the University of Minnesota through ONR support. Participants can remotely implement vector control of AC drives.

Remotely Accessible Hardware Labs for Education and Research in Power Electronics, Power Systems, and Electric Drives

This virtual workshop presented compact, safe-voltage, remotely accessible laboratories developed for education and research in electric drives, power electronics, and power systems. Sessions connected the laboratory platforms to CUSP courses and demonstrated undergraduate, graduate, and pipeline-level experiments using Sciamble Workbench.

Crisis in Power Engineering Education: A National Security Concern

This two-day NSF–NAE workshop convened leaders from government, academia, industry, K–12 education, and community and technical colleges to address the national shortage of power-engineering talent. Participants examined multiple pathways into the field, rewarding careers across the power sector, and freely available CUSP courses and laboratories for workforce development.
