Topology and distribution of synchronous condensers and grid-following inverters

Investigate how network topology and the spatial placement and capacity sizing of synchronous condensers and grid-following inverters influence the interactive dynamics they manifest in large-scale power systems, with the aim of improving understanding of these interactions.

Background

The paper analyzes how synchronous condensers can enhance angular stability, frequency response, and voltage stability in systems with high penetrations of grid-following inverters, emphasizing that synchronous condensers are not grid-forming assets but can strengthen dynamic performance.

Simulation studies reveal that stability outcomes depend sensitively on where and how synchronous condensers are deployed, including their capacity, inertia constants, and the heterogeneity of multiple units. These findings motivate broader, system-level investigation into how network topology and the spatial and capacity distribution of synchronous condensers and grid-following inverters collectively shape interactive dynamics in large-scale grids.

Beyond the scope of this research, there remain major questions about network topology and spatial and capacity distribution of SynCos and GFLs to better understand the interactive dynamics they may manifest in large-scale systems.
