Simulation Methods for Design of Networked Power Electronics and Information Systems

Abstract : This research accomplished four major goals related to tools for design, validation, and operation of future electric ship systems: 1) it developed multi-rate simulation in arbitrary mixed execution environments including tools to optimally configure bi-rate simulation models while considering step size and simulation stability, 2) it developed a new solver that exploits both latency methods and discrete event methods, 3) it developed and demonstrated methods for deeply integrating mature (commercial) simulation software into the VTB framework, and 4) it developed methods to support robust execution of simulations in a distributed computing environment and demonstrated the approach on digital signal processor (DSP) and field programmable gate array (FPGA) systems, and 5) it explored methods to account for the effect on system performance of the coupled networked flows of power and information.
