The models of the multi-zone electric ship are important to developing the ship's operational capability and performance. However, there is not one best model type that can fit all the needs of the engineering process. High-fidelity models are needed as a digital twin to the system hardware for testing and validation purposes. However, a highly detailed digital model of an electric ship does not enable insight and development of analytical control and optimization algorithms. This paper presents a reduced order model (ROM) of a notional four-zone medium voltage AC ship. The advantage of this model is that it is written in a closed-form analytical expression that is appropriate for analysis and high-level supervisory control synthesis. This analysis and development with the ROM is an important first step in the process toward effective and innovative ship designs.
