Abstract

Future shipboard power systems are likely to look and operate much differently than they do today. The changes stem from the need to operate a much wider array of loads, many of which will demand high power in a transient manner. Architectures employing distributed power generation sources and energy storage are attractive, especially when the hooks are built in to rapidly control as many facets of the sources and loads as possible. This however is not always possible as more flexibility comes with increased complexity and costs that are not always easy to implement. As control strategies are developed, testbeds are needed to validate simulations and performance when real hardware is involved. Here a low and medium voltage AC/DC testbed at the University of Texas at Arlington (UTA) is being used to study robust control algorithms that are being developed and modeled by Clarkson University (CU). The testbed emulates one zone of a multi-zone power system and CU has developed algorithms intended for optimized shedding of loads and the ramp rate support of a generator supplying transient loads. Multiple levels of control have been introduced to study the impact each has on maintaining power system operability. The testbed and its integration with these control strategies will be presented along with experimental results collected to date. • Work was financially supported by ONR through grants N00014-18-1-2714, N00014-21-1-2124, and N00014-21-1-2239.
