A modeling approach of Integrated Electrical-Thermal System for early ship design

Thermal issues should be considered in the power system design and operation of an all-electric ship for system efficiency and survivability improvement. The simulation of Integrated Electrical-Thermal System (IETS) can provide the knowledge of interaction between electrical and thermal systems for the designer, but it is computationally expensive. In this paper, a modular modeling method of IETS is presented to reduce system complexity and effort is made on the reduced-order model of integrated power system including optimal power flow solver for the rapid simulation in ship early-stage design. The proposed model is demonstrated in a case study with different scenarios.
