The parallel gas-electric hybrid system has problems such as serious coupling between components and complex energy control strategies. In order to make the multiple components of the system work together and improve the energy efficiency of the system, the parallel gas-electric hybrid tugboat is used as the research carrier of the propulsion system, and the energy management strategy based on ant colony algorithm is designed to make the multiple components of the system work together by means of simulation modeling. The results show that compared with the rule-based energy management strategy, the speed following of the tugboat under the energy management strategy based on ant colony algorithm is increased by 73%. The average energy efficiency increased by 0.7%; Equivalent gas consumption savings of 8.3%. It realizes the accurate control of hybrid system parameters, improves the energy efficiency of the system, and provides technical support for the large-scale popularization and application of gas-electric hybrid system.
