A control strategy for hydrogen fuel cell ship hybrid powertrain based on closed-loop simulation

This paper proposes a control strategy for hydrogen fuel cell ship hybrid powertrain, taking into account the equivalent hydrogen consumption. First, the simulation model of hydrogen fuel cell ship was built based on the mechanistic models. Next, employing heuristic algorithms to iteratively select empirical parameters until the error between simulation results and experimental data meets the required precision. Finally, a control strategy is adopted to concurrently minimize fuel expenditure. Results show that this hybrid powertrain control strategy can reduce equivalent hydrogen consumption by 0.61g while meeting the power demand of the ship.
