With the rapid development of shipbuilding technology, the number of large tonnage ships at home and abroad has increased dramatically. In order to reduce the pollution caused by diesel generators in the port industry, promoting the use of shore power by ships is one of the key tasks of energy conservation and emission reduction in major ports. However, the uncertainty caused by waves and other factors in the operation at sea makes the stability of the interconnection of ship-shore cables decrease. While considering how to improve the stability of shore connection, we should also explore how to maintain the power supply of ship power system when the shore connection is disconnected. Therefore, this paper uses Matlab/Simulink simulation software to simulate and analyze the marine electrochemical energy storage system under ship-shore connected cable faults. Once the cable connection failure, diesel generator or battery energy storage system could be used as a standby power supply to serve as the emergency power supply. By analyzing the advantages and disadvantages of the two standby power sources, the priority application status of the battery energy storage system in the fault scenario of ship-shore connection is first established because of the fast response ability of electrochemical energy storage system. Secondly, compared with diesel generators, the simulation results proved that the energy storage system can not only quickly make up for the power supply gap, but also save electricity costs, improve resource utilization, and reduce noise and environmental pollution when the cable fault occurs in the ship.
