| 摘 要： | 为提高梯次利用电池可重构储能系统的安全性,提出一种梯次利用电池可重构储能系统电池的多级在线安全评估方法。该方法采用可重构储能系统中电池单体、模组的电压、温度等实时监测数据,建立电池及模组的安全评估模型,通过熵权-TOPSIS法对电池电热安全进行量化评估。安全评估方法可在线量化采用不同厂家、批次、种类退役动力电池可重构储能系统的安全状态,依据评估结果实现模组和单体的二级安全预警,完成模组级和单体级的安全风险定位。依据在线安全评估结果,可对梯次利用电池储能系统及时进行拓扑重构、能量调度和温度管理,有效提升系统的安全性,促进梯次利用电池在储能系统中的规模化应用,符合梯次利用储能系统大规模推广建设的现实需要。

| Abstract: | In order to improve the safety of secondary batteries reconfigurable energy storage system, a corresponding multi-level online safety evaluation method is proposed. Based on the voltage and temperature data of the battery monomer and module monitored in real time, this method establishes the safety evaluation model of the battery and module, and quantitatively evaluates the battery electrothermal safety by the entropy weight TOPSIS method. The safety evaluation method can quantify the safety status of the reconfigurable energy storage system using retired power batteries from different manufacturers, batches or types online, so that it can realize the secondary safety early warning of modules and monomers according to the evaluation results, and complete the safety risk positioning of modules and monomers. According to the online safety evaluation results, the topology reconstruction, energy scheduling and temperature management of the secondary batteries energy storage system can operate in time. Hence, this proposed method can effectively improve the safety of the system, promoting the large-scale application of secondary batteries and the large-scale construction of the secondary batteries energy storage system with the practical needs. |
