应用于风力发电的分散式集装箱储能系统设计

Design of Distributed Container Energy Storage System for Wind Power Generation

针对风力发电弃风利用、平滑输出、跟踪出力、参与电网调频的业务需求,设计一个可以满足当前风电企业需求,能实现与风电机组联合运行的分散式储能集装箱系统.该系统综合集成了磷酸铁锂电池组、电池管理系统(BMS)、双向变流系统(PCS)以及能量管理系统(EMS),辅助以集装箱、消防、照明、通风灯系统,并通过专用通信系统接入风电场控制系统,具备与风力发电机组的联合运行能力.经试验测试和现场试运行,该系统具有功率输出精度高、响应速度快、性能稳定、可控性好、管理维护方便等优点,能满足"电网友好型"风电场对储能系统的应用需求.

In view of the business requirements of wind power generation,such as wind abandonment,smooth output,tracking output and participating in grid frequency modulation,a decentralized energy storage container system is designed to meet the needs of current wind power enterprises,which can realize the joint operation with wind turbines.The system integrates the lithium iron phosphate battery pack,battery management system(BMS),two-way converter system(PCS)to And energy management system(EMS),auxiliary to container,fire fighting,lighting,ventilation light system,and access to the wind farm control system through the special communication system,with joint operation ability with wind turbine.The system has the advantages of high power output accuracy,fast response speed,stable performance,good controllability,convenient management and maintenance,and can meet the application requirements of“grid friendly”wind farm for energy storage system.
