摘　　要：本文提出了一种基于超级电容及锂电池的复合储能系统控制策略,用以优化船舶电网中高频负荷突加突卸带来的系统电压波动影响。文中根据不同储能介质的充放电特性,优化不同储能介质功率分配策略,并开展了优化前后控制策略在高频阶跃型负荷系统中的响应特性分析。最后通过复合储能的样机系统,验证优化后功率分配策略的可行性,证明了所提优化控制策略在船舶电网可执行性。This article proposes a control strategy for a hybrid energy storage system based on super capacitor and lithium battery to optimize the impact of system voltage fluctuations caused by sudden loading and unloading of high-frequency load in ship power grid.Based on the charging and discharging characteristics of different energy storage media,the paper optimises the power allocation strategy of the DC converter connected to the grid,and analyses the response characteristics of the control strategy before and after optimization in the high-frequency step load system.Finally,the feasibility of the optimized control strategy has been verified through a prototype system of hybrid energy storage,which proves the feasibility of the proposed optimized control strategy in ship power grid.
