This paper proposes a model of a hybrid fuel cell-battery propulsion system for a Crew Transfer Vessel (CTV). A multi-scheme energy management strategy is also applied to the EMS block to optimize energy flow. A fuel cell-battery hybrid system was developed by integrating PEM fuel cells with Li-ion batteries to provide electricity to the propeller propulsion system, and hotel load. Accordingly, a hybrid battery/fuel cell propulsion system with the capability of both charging the battery at both stations and bunkering the fuel tanks will be proposed. During cruising, docking, stopping, accelerating, and loitering phases of a ship journey, power distribution will be carried out, and energy requirements will be investigated at different EMS strategies with the objective of maximising system efficiency. A simulation using MATLAB/Simulink software is conducted using operational profiles at different power load conditions. Simulation is conducted using four EMS schemes: state-based, equivalent fuel consumption minimization strategy (ECMS), a charge-depleting and charge-sustaining strategy (CDCS), and classical proportional-integral (PI) controller-based, which are all selected based on power mode and battery SOC. Results show proposed multi-scheme strategy can lead to significant energy and cost savings, with a maximum of 4% and 12% respectively.

摘要

This paper proposes a model of a hybrid fuel cell-battery propulsion system for a Crew Transfer Vessel (CTV). A multi-scheme energy management strategy is also applied to the EMS block to optimize energy flow. A fuel cell-battery hybrid system was developed by integrating PEM fuel cells with Li-ion batteries to provide electricity to the propeller propulsion system, and hotel load. Accordingly, a hybrid battery/fuel cell propulsion system with the capability of both charging the battery at both stations and bunkering the fuel tanks will be proposed. During cruising, docking, stopping, accelerating, and loitering phases of a ship journey, power distribution will be carried out, and energy requirements will be investigated at different EMS strategies with the objective of maximising system efficiency. A simulation using MATLAB/Simulink software is conducted using operational profiles at different power load conditions. Simulation is conducted using four EMS schemes: state-based, equivalent fuel consumption minimization strategy (ECMS), a charge-depleting and charge-sustaining strategy (CDCS), and classical proportional-integral (PI) controller-based, which are all selected based on power mode and battery SOC. Results show proposed multi-scheme strategy can lead to significant energy and cost savings, with a maximum of 4% and 12% respectively.
