Dr. Roger Dougal

Professor
Thomas Gregory Professorship

Prof. Dougal is the director of the Virtual Test Bed project, which focuses on interdisciplinary simulation and visualization of modern power distribution systems, especially isolated or mobile power systems. Other research programs explore the integration of electrochemical converters and storage devices into hybrid systems that meet the demanding requirements for continuous and peak power in mobile platforms. In the past, Prof. Dougal has had interests in pulsed power systems, especially plasma-based switching devices, and electron beam generation and applications, and laser systems and electro-optics. Current projects:

• Virtual Test Bed: The Virtual Test Bed project is a multi-disciplinary, multi-university effort to develop a comprehensive simulation and virtual prototyping environment for advanced electric power systems. The VTB is unique in allowing simulation of multi-technical systems by importing models from discipline specific source languages to a common workspace. In addition to the main project to develop the VTB, a current version of the software supports a half-dozen multidisciplinary research programs within the college of engineering and serves as the integrating element for work on advanced electrochemical energy sources, power electronics, distributed power systems, and control systems.
• Fuel-cell Power Systems have complex dynamics. Plant optimization is inherently a multidisciplinary issue. The aim of this project is to create a full dynamic model of a fuel cell power plant that operates within the context of a real load environment, then to assess the dynamic performance of that system with an eye towards optimizing its functionality.
• Hybrid Advanced Power Systems focuses on the optimal integration of (primarily) electrochemical energy resources in portable power systems. The focus is on optimizing the size, weight, and cost of electric power sources that include elements such as fuel cells, advanced batteries, ultracapacitors, and power electronics for applications ranging from satellite power systems to hybrid electric vehicles and personal electronics.
