以内蒙古某一实际分布式风电-电池储能系统的设计和运行效果为基础,对影响其可用性的关键因素进行了分析。结果显示:能量管理系统的设计需要考虑功率补偿控制以抵消储能系统内部功率损耗;功率转换系统(power conversion system,PCS)的响应时间对系统性能具有重要影响,控制算法的功率指令周期需与PCS响应时间匹配;储能系统的结构和布局也对储能系统的环境适应性有着重要影响。风电-电池储能系统可用性对其实际推广应用具有重要影响,该文对影响风电-电池储能系统应用过程中出现的问题提出了相应的解决方法,为风储系统的推广与应用提供参考。

Availability of Distributed Wind Power-Battery Energy Storage System

Based on the design and operation of a real wind power-battery energy storage system, this paper analyzes the key factors that affect its availability. The results show that: the design of energy management system should consider the power compensation control to offset the internal power loss of the energy storage system;the response time of power conversion system (PCS) has the important influence on the system performance, so the power instruction cycle of control algorithm should be designed according to the response time of PCS;the structure and layout of the energy storage system have important influence on its environmental adaptability. The availability of wind power-battery energy storage system has important influence on its practical application. This paper proposes the corresponding solutions for the application of wind power-battery energy storage system, which can provide reference for the popularization and application of wind storage system.
