中文摘要

电网运营商要求可再生能源发电单元(RGU)具备特定的动态特性,以支持电网稳定并抑制新型振荡问题。本文提出了一种新型分析方法,用于设计可再生能源同步发电机(SSG)同步功率控制器(SPC)单元,旨在有效缓解由RGU与电网动态交互引起的低频机电振荡,提升系统稳定性。

English Abstract

Grid operators require grid-connected renewable generation units (RGUs) to provide specific dynamic features. Among those features, the RGUs must support the dynamic performance of the power grid as well as operate in such a way to ward off new issues in the power system. Recently, unfavorable oscillatory modes have appeared through the grid connection of RGUs due to their dynamic interaction with...
