Abstract
"Time-domain simulation plays a large part in the design and analysis of power systems. Given the expanding needs of circuit system design packages, it is of the utmost importance to have computationally efficient methods of time-domain simulation available. This thesis describes the development and application of the multi-rate numerical integration techniques for the dynamic simulation of power-electronic-based systems (DCZEDS) that are composed of AC power supply, DC power distribution, and propulsion load subsystems with different time scales.
In this project, the multi-rate algorithm is implemented on the DCZEDS power system with two-time scales. Various implementation strategies are discussed to increase the efficiency of the algorithm. These include partitioning strategies for initial adaptive partitioning of the differential variables and extrapolation/interpolation guides to account for the coupling between these two-time scale partitions. The basic multi-rate algorithm is described and several results pertaining to the numerical convergence, stability, and accuracy of the method are presented. The multi-rate algorithm is shown to be computationally efficient when used to simulate systems in which the fast subsystems are a small portion of the system as a whole. The accuracy of the multi-rate algorithm is preserved by choosing integration step sizes according to the local truncation error for the different state variables"--Abstract, page iii.
