Derivation of Power System Module Metamodels for Early Shipboard Design Explorations

Future highly electrified ship designs must incorporate emerging technologies for high power energy conversion to enable smaller, highly electrified ship. Smart Ship System Design addresses this challenge by allowing design space explorations across a range of architectural implementations. Scalable models for power conversion and distribution equipment are needed that will predict size, weight, losses, cost and reliability vs. such design space variables as voltage, frequency and power levels, technology insertion, topological choices, etc. This paper proposes a methodology for producing metamodels from a virtual prototyping process optimized over a range of objectives. The approach is demonstrated for a modular multi-level converter-based MVac to MVdc active rectifier.
