摘要

在当前电池组建模中

往往忽略内部参数差异

将其简化为单体进行仿真。但是

对于电池储能系统

其规模较大

内部单体参数往往差异明显

需要考虑不一致性建模。通过对电池单体和电池组进行循环寿命测试

研究电池老化过程中参数的变化规律。在此基础上

搭建了适合于储能电站优化设计、控制策略参考的考虑不一致性的电池储能系统的详细模型

并将该模型应用于储能系统平抑风电波动的仿真。仿真结果显示

详细模型能够比简化模型提供更优的控制参考。

Abstract

The battery energy storage system(BESS)is considered an effective method for wind power stabilization. The inconsistency of BESS is always ignored in current simulations with the whole BESS simplified as a battery cell. However

in practice

because of the large scale of batteries

the cell to cell variation is quite common in BESS. In the circumstances

the simplified model would cause overcharge or discharge

which significantly shortens the lifetime of batteries. This paper discusses the deterioration of battery pack and develops a detailed Thevenin model for BESS with distinct inconsistency. The presented model is suitable for power electronic design and offers useful information for control strategy. The proposed model is applied to fluctuation stabilization of wind power to show its advantage over the simplified model.
