In order to further improve the energy-saving and voltage stabilizing effect of the stationary energy storage system (ESS), this article tries to adopt the battery-supercapacitor (SC) hybrid ESS (HESS) as stationary ESS. The advantages of stationary HESS are verified by an example. An adaptive energy management framework for stationary HESS is proposed. A power distribution strategy is proposed to solve the adaptability of two energy storage media to the load variation of rail transportation power system, and to a certain extent, the battery degradation is delayed. The proposed strategy can not only realize the reasonable power-sharing between battery and SC considering the influence of headway on regenerative braking energy but also can keep the battery’s charge and discharge capacity for a long time by using fuzzy logic control (FLC). A simulation is carried out to illustrate the advantages of the proposed energy management strategy (PEMS). Finally, the PEMS is compared with two conventional strategies by the hardware-in-the-loop experiment platform, where it is shown to provide better performance (inferred through increases of 1.1% and 5.7% in energy conservation rate, 0.82% and 6.4% in voltage stabilization rate, and reduction of 2.26 and 0.36 A in the root-mean-square value of battery current at different headway).

固定式混合储能系统的自适应能量管理策略


为了进一步提高固定式储能系统（ESS）的节能和稳压效果，本文尝试采用电池-超级电容器（SC）混合ESS（HESS）作为固定式ESS。通过算例验证了固定式HESS的优点。提出了一种固定式 HESS 的自适应能源管理框架。提出一种功率分配策略，解决两种储能介质对轨道交通电力系统负荷变化的适应性，并在一定程度上延缓电池的退化。该策略不仅可以考虑车头时距对再生制动能量的影响，实现电池和SC之间的合理功率共享，而且可以利用模糊逻辑控制（FLC）长期保持电池的充放电能力。通过仿真来说明所提出的能源管理策略（PEMS）的优点。最后，通过硬件在环实验平台将PEMS与两种传统策略进行比较，结果显示PEMS具有更好的性能（节能率分别提高了1.1%和5.7%，节能率提高了0.82%和6.4%）电压稳定率降低，不同车距下电池电流均方根值降低2.26和0.36A）。
