Large, immediate changes in electrical loading cause stresses in power systems. In large power systems, such as the grid used in residential, commercial and industrial applications, the typical change in electrical loading is a very small percentage of the power ratings of the electrical generators. As such, abrupt changes in electrical loading will cause relatively little stress to the power system. In naval applications, however, the distribution systems have a much lower power rating, so the stresses from load changes are much more significant. This thesis presents a novel solution to reduce the undesired effects of these load changes. Through the use of an energy storage system (ESS), switch-mode DC power converter, and an engineered control scheme, the undesired effects of large pulsed loads may be mitigated.
A physics-based model of the system was constructed to provide a proof of concept of the solution, and is verified utilizing a laboratory prototype. The simulated and experimental measurements are compared against the specified constraints provided in MIL-STD-1399.Outstanding ThesisLieutenant, United States NavyApproved for public release.
