Modeling and Design of Parallel Load Distribution Control System
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.
