Numerical Methods Combat Power and Energy Systems (CPES)

The US Navy has been moving towards Integrated Power Systems (IPS) for Naval ships because they separate the prime movers from the propulsion train, maximize the efficiency, reduce acoustic signatures, improve redundancy, improve survivability, and provide compatibility with the increasing power requirements from advanced weapons, sensors, and radar systems. In electric warship design the ability to rapidly test many architectural concepts by simulating operational activities is critical for successfully completing early stage design activities. Further, integration of IPS design with LEAPS is essential for compatibility with the Navys overall ship design process. Available power system simulation tools require fidelity of information and computational resources that are too high for early stage design activities. The proposed research will address this need and create an Emulator Toolkit for LEAPS. Emulators (i.e. surrogate models) will represent the time varying behavior of components and/or subsystems of an IPS. A mathematical synthesis method will be integrating the emulators for creating a surrogate model for the entire IPS. During Phase I alternative mathematical methods for generating and integrating the emulators will be investigated and documented. A down selection of the most appropriate methods will be completed and an implementation plan compatible with LEAPS will be made.
