Modeling and simulation of an electric warship integrated engineering plant for battle damage response

Novel continuity-of-service metrics are applied to perform proof-of-concept simulation-based design of a complex, dynamically interdependent electro-thermal-fluid-spatial-control system subjected to hostile disruptions. The power system models are based on experimentally validated reduced-scale and reduced-complexity testbed models which are representative of U.S. Navy Next Generation Integrated Power Systems. In collaboration with an industry partner, representative thermal and spatial models were incorporated into the layered simulation. This time-domain simulation was used to quantify performance to a specific disruption in terms of a weighted aggregate continuity of service to vital loads. By extension, system vulnerability was quantified using a population of likely threats. Optimization-based early design space exploration was shown to dramatically decrease the notional ship integrated engineering plant vulnerability by improving the performance of a worst-case casualty by a factor of 6. These achievements establish the metrics, methods, and tools to perform quantitative optimization-based early design space exploration for complex, dynamically interdependent systems such as an electric warship.
