摘要 受DC-DC模块和电池管理系统成本及其容量的限制,传统储能系统在直流配电网中的应用受限。本文提出一种基于退役电池搭建的直挂母线式储能系统,该储能系统可以随着直流配电网电压波动,以投退不同电池组模块的方式来调节储能电池的出口电压,实现储能电池充放电的目的。最后,利用Matlab/Simulink仿真和搭建的直挂母线式储能系统验证了直流配电网系统电压突变时,储能电池组可以通过投退各电池组模块的方式实现储能电池组的充放电功能。

Abstract:Due to the capacity and cost of DC-DC module and battery management system (BMS), the application of traditional energy storage system in DC distribution network is limited. Thus, a scheme of energy storage system without DC-DC and BMS is proposed to reduce the cost of energy storage. The output voltage of the energy storage system changes as the fluctuation of DC distribution network voltage. By controlling the state of battery module switch, the output voltage of the energy storage battery could be adjusted to charge or discharge the energy storage battery. Furthermore, the automatic regulation function of DC distribution network voltage is realized by controlling the state of battery module switch. Finally, Matlab/Simulink simulation and experiment show that when the DC distribution network voltage changes suddenly, the energy storage battery system can realize the charging and discharging function.
