Abstract: The advantages of hybrid ships in energy conservation and emission reduction are increasingly prominent in the context of countries around the world paying increasing attention to such matters. Energy management is the key to achieving energy conservation and emission reduction on the premise of ensuring power performance. This paper summarizes the research progress and status of hybrid ship energy management. First, the energy management objectives are summarized in the three aspects of reliability objectives, economy objectives and environmental protection objectives. Second, the energy management strategies are compared and analyzed from the perspectives of rules and optimization, and the advantages, disadvantages and application conditions of the existing energy management strategies are summarized and analyzed deeply and comprehensively. Finally, according to the gaps in the existing research, the future research directions of hybrid ship energy management are predicted.
