Research on control strategy of hybrid electric ship based on minimum equivalent fuel consumption

In order to improve the economy of the hybrid electric-electric ship, the parallel hybrid electric ship is taken as the research object, and an energy control strategy of the electric-electric hybrid ship based on the minimum equivalent fuel consumption is proposed. The efficiency factor and its correction function are used to maintain the balance of battery power, and the target optimization function is adjusted to control the power consumption rate of the power battery, thereby realizing the optimization of the control strategy for the traveling ship. Finally, Matlab/Simulink is used for simulation. The experimental results show that when the control strategy with the minimum equivalent fuel consumption is used, the fuel consumption is 1.95L less than the CD-CS-based strategy, and the fuel saving rate is 31.2%. At the same time, the engine and motor work Efficiency is greatly improved.
