摘要
该文从锂电池和燃料电池的混合储能特性出发,针对已有文献的拓扑结构,对比选取适用于功率分配的混合储能拓扑模型和建模方法,并在组合过程中通过分析选取最合适的变换方式组成混合储能模型,最后通过仿真验证所提模型可在进行功率分配的前提下提高储能系统荷电状态偏移,延长储能系统寿命.
Abstract
Starting from the hybrid energy storage characteristics of lithium batteries and fuel cells,this paper compares and selects hybrid energy storage topology models and modeling methods suitable for power distribution according to the topology structures of existing literature,and selects the most suitable hybrid energy storage topology model through analysis and selection during the combination process.A hybrid energy storage model is formed by appropriate transformation methods.Finally,it is verified by simulation that the proposed model can improve the state of charge offset of the energy storage system and prolong the life of the energy storage system under the premise of power distribution.
