船舶多时间尺度能源管理系统研究

Research on Ship Multi Time Scale Energy Management System

近年来随着能源日益短缺,船舶动力系统正向新能源化升级转型,但新能源出力的不确定性也为系统的经济、安全运行带来了新的挑战。因此传统船舶能源管理已不再适用,亟需适用于现代船舶的综合能源管理系统。针对以上情况,提出了一种上层采用能源优化调度、底层协调控制以及与智能算法相结合的综合能源管理策略,构建了新能源船舶微电网系统模型,并在相应的仿真平台上模拟了船舶处于加速航行、正常航行、减速航行以及停泊等四种不同运行工况。最后,在Matlab/Simulink平台上搭建了系统各部分的仿真模型,通过仿真结果,验证了所提出的策略能够在维持直流侧母线电压和系统稳定的前提下,实现供需双侧功率的高效平衡。

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brought new challenges to the economic and safe operation of the system.Therefore,traditional ship energy management is no longer applicable,and there is an urgent need for a comprehensive energy management system suitable for modern ships.In response to the above situation,a comprehensive energy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.
