Professor Peter W. Sauer holds the W. W. Grainger Chair in Electrical Engineering in the Department of Electrical & Computer Engineering at the University of Illinois. He is working on projects related to power system operational reliability. These include the modeling and simulation of loads, generators, and smart grid components. They also include the challenge of dynamic modeling of renewable resources such as wind turbines and solar arrays. Issues such as low inertia generation are being examined to determine their impact on contingency analysis, system recovery following disturbances, and automatic generation control. Sauer is a co-founder and Site Director of the NSF-sponsored Power Systems Engineering Research Center. He served as the program director for power systems at the National Science Foundation from September 1991 to August 1992. He was a cofounder and chairman of the Board of Directors of PowerWorld Corporation from 1996 to 2001. He served in the U.S. Air Force as a facilities design engineer from 1969 to 1973 (Langley AFB, VA) and 1982 to 1998 (Chanute AFB and Scott AFB, IL). He is a registered professional engineer in Virginia and Illinois, a Fellow of the IEEE, and a member of the U.S. National Academy of Engineering.
