In recent years,with the increasing shortage of energy,the ship power system is transitioning towards new energy upgrading. However,the uncertainty of new energy output has also brought new challenges to the economic and safe operation of the system. Therefore,traditional ship energy management is no longer applicable,and there is an urgent need for a comprehensive energy management system suitable for modern ships. In response to the above situation,a comprehensive energy management strategy using energy optimization scheduling was proposed,coordinated control at the upper level,and a combination of intelligent algorithms. A new energy ship microgrid system model was constructed,and four different operating conditions of the ship on the corresponding simulation platform were simulated,including accelerating navigation,normal navigation,decelerating navigation,and berthing. Finally, simulation models of various parts of the system on the Matlab/Simulink platform were built,and the simulation results verify that the strategy proposed can achieve an efficient balance of power supply and demand on both sides while maintaining the DC side bus voltage and system stability.
