摘　　要：锂离子电池作为目前主要的新型储能技术,得到了高度重视和发展,单个电池储能电站的装机规模越来越大。由于大型储能电站往往由众多小容量、标准化的储能系统单元聚集而成,如何实现多储能单元集群的高效控制与管理,是储能电站整体性能的重要保证。针对大型储能电站的集控技术进行研究,在系统功能需求分析的基础上,提出了基于EtherCAT的集控架构和网络分层方法,对集控管理层、单元控制层和受控设备层进行了优化设计,并对通信能力进行了计算。最后搭建了实验平台验证了所提架构和设计的有效性,为大型储能电站参与电力系统多种运行的快速性和可靠性提供了技术参考。Lithium-ion batteries,the leading new energy storage technology,have been highly valued and developed.The installed capacity of single-battery energy-storage plants(BESP)continues to grow.Given that a BESP is often composed of many small-capacity standardized energy storage system units,achieving efficient control and management of multiple energy storage unit clusters is an essential guarantee for optimizing the overall performance of energy storage power plants.Cluster control technologies of the BESP were investigated in this study.Based on the BESP control functional requirements analysis,a control architecture and network-layering method based on EtherCAT were proposed.Optimizations were made for the cluster control and management,unit control,and controlled equipment layers,and the communication capability of the BESP control system was calculated.Finally,an experimental platform was set up to verify the effectiveness of the proposed architecture and design process.This provides a technical reference for large-scale BESP to contribute to the rapid and reliable operation of various power systems.
