构网型控制下电池储能系统的次同步阻尼

Subsynchronous Damping by Battery Storage System in Grid-Forming Control

语言:

中文摘要

风电场因网侧变流器与弱电网阻抗交互易产生次同步振荡(SSO)。本文探讨了利用电池储能系统(BESS)通过构网型(GFM)控制技术来抑制SSO,并兼顾电网辅助服务功能。研究分析了BESS在公共连接点(PCC)或直流侧接入对系统稳定性的影响。

English Abstract

Wind farms are susceptible to subsynchronous oscillation (SSO) issues due to the interaction between the grid-side converter (GSC) and the weak-grid impedance. Integration of battery energy storage system (BESS) to damp SSO became popular due to its ability to also provide various grid services. Generally, BESS can be externally integrated at the PCC or internally integrated at the dc link of the ...
