Modeling and Simulation of a Hybrid Electric Propulsion System of a Green Ship

In this work, the hybrid electric propulsion system of a marine vehicle was modeled in MATLAB Simulink and SimPowerSystems. Models of each of the propulsion components were developed and incorporated into a complete system propulsion model. A rule-based supervisory mode controller was constructed which specifies the combination of onboard power sources to be used throughout the mission cycle. The hybrid electric propulsion and control model was simulated on a dSPACE hardware-in-the-loop platform. For each simulation, the energy storage system state of charge, HEV mode, propeller motor drive speed set point, and hotel load were specified. This study forms the foundation for further research in ship hybrid electric propulsion system design and power management.
