Abstract The increase in the use of Converter-Interfaced Generation (CIG) in the power system will require these generators to not only feed the power but also establish the voltage and maintain the grid stability. Virtual Synchronous Generator (VSG) control of the CIG is proposed to fulfill this requirement since it mimics the dynamics of synchronous generation. This paper takes the all-Island Irish transmission system as an example to investigate the frequency stability of the system as it migrates towards 100% CIG under VSG control and quantifies the minimum conditions for frequency support to sustain the system under 100% CIG. Simulations are carried out considering the worst contingency in the Irish grid which is the loss of largest infeed, namely, the disconnection of the HVDC interconnector to the UK. The results are compared and discussed considering other scenarios that include primary frequency control of conventional power plants.

使用虚拟同步发电机控制的 100% 转换器接口发电：基于爱尔兰系统的案例研究

摘要 随着电力系统中转换器接口发电（CIG）使用的增加，这些发电机不仅需要供电，还需要建立电压并维持电网稳定。建议 CIG 的虚拟同步发电机 (VSG) 控制来满足这一要求，因为它模仿了同步发电的动态。本文以爱尔兰全岛传输系统为例，研究了系统在 VSG 控制下向 100% CIG 迁移时系统的频率稳定性，并量化了频率支持以维持系统在 100% CIG 下的最低条件。进行模拟时考虑了爱尔兰电网中最糟糕的突发事件，即最大馈电损失，即与英国的 HVDC 互连器断开连接。
