Development of a Multicore Power System Simulator for Ship Systems

An important impediment to using widely available software to simulate the behavior of advanced power systems for electric ships is that the simulation time is too long to be practical. Consequently, the Center for Electromechanics at the University of Texas at Austin (UT-CEM) is developing a multicore power system solver to simulate large shipboard power systems. In its first year of development, the focus is on testing CEM’s solver (CEMS) for accuracy.

The paper, “Development of a Multicore Power System Simulator for Ship Systems,” coauthored by Fabian Uriarte and Bob Hebner and presented at the 2011 IEEE Electric Ship Technologies Symposium (ESTS), April 10-13, 2011 in Arlington, Virginia, provides an overview of the major traits of CEMS, and compares its simulation results to the well-known commercial power system simulator SimPowerSystems. Preliminary results show that accuracy is maintained and improved in specific test cases.
