摘要
多个储能装置并联时,如何提高储能装置剩余容量的利用率,完成每个储能装置能量按需分配,并保证系统平稳安全运行的问题受到研究人员的关注.对多个储能装置并联系统的能量管理策略进行研究,基于输出电流和储能装置的剩余容量引出负荷系数的概念,并提出了中间负荷系数控制模式,同时基于此控制模式进行了建模和三环控制系统传递函数的推导.通过3个储能装置并联系统进行仿真和实验,验证了所提负荷分配控制策略的稳定性与合理性,避免了储能装置因过度放电或过度充电提前退出运行,并达到了按照剩余容量进行负荷分配的目标.
Abstract
When multiple energy storage devices are connected in parallel,how to improve the utilization rate of the remaining capacity of the energy storage device,complete the distribution of each energy storage device as required,and ensure the smooth and safe operation of the system has attracted the attention of researchers.This paper derives the concept of load factor based on output current and residual capac-ity,and proposes an intermediate load factor control mode.At the same time,based on this control mode,the modeling and the derivation of the transfer function of three-loop control system are carried out.The stability and rationality of the load distribution control strategy are verified by simulation and experiment of three parallel systems of energy storage devices,and the goal of load distribution according to the residual capacity is achieved.
