Development trend and hotspot analysis of ship energy management

With the continuous promotion of energy saving and emission reduction policies, the development of highly efficient and low emission green ships is the priority for the industry. Hybrid (or all-electric) ships that consider multiple forms of energy storage and clean energy have the potential of energy saving which have been widely studied. Energy management as a key technology for coordinating the efficient working of all energy sources on board ships has become a focus of research. Firstly, this paper visualises and analyses the literature in this field by CiteSpace to clarify the development trend of ship energy management. The research hotspots in energy management are summarised by keywords and clustering: optimal design of ship power (propulsion) systems, control of microgrids, efficient energy management strategies (EMS) and its test verification. Subsequently, the structure or classification, research focus and key technologies of these four contents are analysed in detail. Finally, the persisting problems were summarised, and corresponding solutions were proposed. The results show that ship energy management is a systematic problem, which needs to be comprehensively considered from multiple perspectives such as design selection, energy transmission, operation management, and performance evaluation. Thereinto, power quality control, multi-objective collaborative optimisation, algorithm fusion and test verification are key to the research.
