Initial design considerations of shipboard power distribution grids require a priori load dynamics assumptions for size assessment, power/energy requirements, and system stability considerations. For the analysis of dc micro-grids, power processing units and dynamic loads are often assumed destabilizing constant power loads for simplified stability studies. The constant power load is shown to be valid...
A shipboard power system is self contained, tightly coupled, and small enough to allow nearly real time state estimation, given the right equivalent circuit representations. Redirecting power flow is the preeminent task of reconfiguration. This redirection should be accomplished in less than two cycles, while never compromising system stability or power delivery to critical loads. These performance...
The goal of an automatically reconfigurable shipboard power system is to prevent self-inflicted damage and to generate and utilize power in an efficient and reliable manner. To achieve this objective, the system must balance response time with decision accuracy. Speed of calculation is achieved by (1) utilizing a more efficient method of calculating optimization parameters and (2) monitoring indicating...
