摘要针对混合储能系统基于SOC的功率分配方法,参照滤波器时间常数的概念,定义“等效时间常数”,将其作为功率分配效果的评判指标,并通过仿真证明了定义的合理性。在仿真分析等效时间常数影响因素的基础上,比较基于SOC和滤波的两类功率分配方法对应时间常数可能的取值范围;进而以时间常数作为分配效果的表征参数,解释了基于SOC的功率分配方法优于滤波法的原因。

Abstract：For the hybrid energy storage system (HESS) power sharing strategy based on the state of charge (SOC), the definition of equivalent time constant is proposed for its similarity to the time constant of low-pass filter. Attempting to make a general evaluation for different sharing strategies, the time constant is used as an indicator of power sharing results in this paper. Simulation results are presented to verify this indicator and its influencing factors. For two power sharing strategies of HESS, based on SOC or filtering, the advantage of the former is explained by comparing value ranges of the equivalent time constant and the time constant of the filter.

Key words： Hybrid energy storage, power sharing, state of charge, equivalent time constant
