International maritime transport organizations are proposing regulatory actions and strategies
aimed at decarbonizing the sector to reduce its greenhouse gas (GHG) emissions, which currently
constitute around 3% of the global total. Hybrid propulsion systems have significant potential in this
respect, as a means of power-saving in ships. This paper describes a high-fidelity benchmark for
hybrid-electric vessels, combining diesel generators and batteries. The benchmark consists of detailed
models, the parameters of which are provided so that the models can be reproduced. The proposed
hybrid-electric ship topology and control system was validated using real-time hardware-in-the-loop
(HIL) simulations on a Typhoon HIL402 platform. The results provide a detailed analysis of the operation
of the different components under varying conditions, which should be useful in prototyping
these kinds of systems. In addition, the response of the system was evaluated with regard to potential
disturbances resulting from the control system’s operation. The results show the system performed
correctly during these transitory events, with no undesirable responses
