The modelling and three-level control of a hybrid propulsion system for a green ice-capable ship

The decreasing of Arctic sea ice provides opportunities for commercial shipping between Asia and Europe due to its shorter distance. However, the environment is vulnerable pollutants from activities. Therefore, it important consider impacts activities in Northern Sea Route (NSR), especially with a view possibility reducing emissions short-lived pollutants. In this paper, modelling hybrid propulsion system conducted implemented Matlab Simulink. A 3-level control strategy efficiency power sources taken into consideration, applied ensure stability voltage frequency, as well through minimizing fuel consumption. target journey specific loading condition, which related NSR shipping, has been test performance diesel electric system, simulation results three-level research can offer up 22.7% savings compared DC over typical operating cycle. This justifies use more environmentally friendly future ice-capable ships NSR. Finally, sensitivity analysis find main factors, influence
