Abstract

This research contributes to the understanding of small signal stability in low-inertia systems and provides a foundation for future studies on large-scale grids, enhancing the boundaries of small signal stability analysis. Various grid models incorporating grid-following and grid-forming converters with droop control are developed, simulated, and analyzed. The study highlights the advantages of eigenvalue-based small signal stability analysis in assessing system stability and mode contributions, while also identifying limitations in handling control discontinuities and the computational burden of large-scale inverter-dominated grids. Results prove that participation factor analysis correlates modes to specific control sections. The main contribution is the observability of inter-converter interaction depending on grid strength, which extends the scope of eigenvalue-based small signal stability analysis into converter-driven stability.
