Assessment of Power System Stability Considering Multiple Time-Scale Dynamics: Insights into Hopf Bifurcations in Presence of GFL and GFM IBRs
Luis David Pabon Ospina, Martin Braun, Sushobhan Chatterjee +1
Real power systems exhibit dynamics that evolve across a wide range of time scales, from very fast to very slow phenomena. Historically, incorporating these wide-ranging dynamics i…
Voltage Stability of Inverter-Based Systems: Impact of Parameters and Irrelevance of Line Dynamics
Sushobhan Chatterjee, Sijia Geng
This paper investigates voltage stability in inverter-based power systems concerning fold and saddle-node bifurcations. An analytical expression is derived for the sensitivity of t…
Effects of Line Dynamics on Stability Margin to Hopf Bifurcation in Grid-Forming Inverters
Sushobhan Chatterjee, Sijia Geng
This paper studies the parameter sensitivity of grid-forming inverters to Hopf bifurcations to address oscillatory instability. An analytical expression for the sensitivity of the…
Unified Control Scheme for Optimal Allocation of GFM and GFL Inverters in Power Networks
Sushobhan Chatterjee, Sijia Geng
With the rapid adoption of emerging inverter-based resources, it is crucial to understand their dynamic interactions across the network and ensure stability. This paper proposes a…
