This study proposes a hybrid marine power system combining dual-fuel generators, a fuel cell, and Vanadium Redox Flow Batteries (VRFB). Rigorous verification and validation of the dynamic modelling and integration of the system are conducted. A case study for the application of the hybrid propulsion system to a passenger ship is conducted to examine its time-variant behaviour. A comprehensive model of the reversible and irreversible capacity degradation of the VRFB stack unit is proposed and validated. The capacity retention of the VRFB stack is simulated by being integrated within the hybrid propulsion system. Reversible degradation of the VRFB stack is precisely predicted and rehabilitated based on the predefined operational schedule, while the irreversible portion is retained until the affected components are replaced. Consequently, the advantages of the VRFB system as an on-board ESS are demonstrated through the application of a hybrid propulsion system for liner shipping with fixed routes.

本研究提出了一种结合双燃料发电机、燃料电池和钒氧化还原液流电池 (VRFB) 的混合船用动力系统。对系统的动态建模和集成进行了严格的验证和验证。对混合动力推进系统应用于客船的案例研究进行了研究，以检查其随时间变化的行为。提出并验证了 VRFB 堆叠单元可逆和不可逆容量退化的综合模型。VRFB 堆栈的容量保持是通过集成在混合推进系统中来模拟的。VRFB 堆栈的可逆退化是根据预定义的操作时间表精确预测和修复的，而不可逆部分将被保留，直到更换受影响的组件。最后，
