摘要

提出了一种三相电池储能系统(BESS)，该系统可在微网并网和孤岛模式下运行。当连接到MG时，一个增强的频率控制器，覆盖主要的两个频率控制水平，即主频率和次频率，控制BESS有功功率。当MG电能质量下降到一定水平以下时，系统可以切换到孤岛模式，为本地负载供电。只有当BESS电压与MG电压顺利重新同步后，才能完成重连接。通过计算机仿真，对三相BESS的控制方案进行了评估。

An enhanced three-phase battery energy storage system for frequency control in microgrids

This paper presents a three-phase battery energy storage system (BESS) operating in both microgrid (MG) connected and islanded modes. When connected to the MG, an enhanced frequency controller, covering the main two frequency control levels, i.e. primary and secondary, governs the BESS active power. If the MG power quality worsens below a certain level, the system is able to switch in island mode and to supply the local loads. The reconnection is accomplished only after the BESS voltage is smoothly resynchronized with the MG voltage. The proposed control solution for a three-phase BESS is assessed by means of computer simulations.
