摘要
介绍了电流检测方法和级联型储能装置电流控制策略,基于仿真平台验证了级联型储能装置用于改善电网无功、谐波和负序电流的效果,分析了几种控制模式对电池侧电流造成的影响,指出了级联型储能装置用于电能质量综合治理时在设计和控制中应注意的相关问题。
In this paper,the method of target current detection and the control strategy of cascaded battery energy storage system（BESS）are introduced. Based on the simulation platform,the effects of cascaded BESS to improve the reactive power,harmonics and negative sequence current of the grid are verified,and the influences of several control modes on the battery current are analyzed. Besides,this paper points out the related problems that should be paid attention to in the design and control of cascaded BESS for comprehensive control of power quality.
