Cross-platform validation of notional baseline architecture models of naval electric ship power systems

Abstract

Abstract-To support efforts in assessing the relative merit of alternative power system architectures for future naval combatants, the Electric Ship Research and Development Consortium (ESRDC) has developed notional baseline models for each of the primary candidate architectures currently considered, medium-voltage DC (MVDC), conventional 60 Hz medium-voltage (MVAC), and high-frequency medium-voltage (HFAC). Initial efforts have focused on the development of a consistent set of component models, of which the system models can be comprised, and the basic definition of the system models. The broader objectives of the consortium, however, go beyond the definition of the baseline models. The focus is on the process by which the models are implemented in software and validated, the process by which the performance of the disparate system models are objectively and quantitatively assessed and compared, and, ultimately, the process by which the relative merits of the architectures may be assessed. This paper focuses specifically on cross-platform component validation.

All-Electric Ship Design: From Electrical Propulsion to Integrated Electrical and Electronic Power Systems

“…Moreover, in complex systems the overall optimal design solution is rarely the composition of the optimal solutions of the subdesign processes, making it necessary to develop a design methodology that is able to balance the IEPS design with the other subsystems. Several design methodologies can be found in the literature [15]- [21], but the most relevant three are the design spiral, the collaborative concurrent design, and the design space exploration. Among these, the simplest one is the former, which implies performing sequentially all the design activities moving from the most general detail level (achieved during concept design) to more detailed design levels (Fig.…”
