Decentralised Plug-and-Play Stability Conditions for AC Grids-Part II: Unstable Subsystems
Liam Hallinan, Ioannis Lestas
Part I of this paper presented a decentralised framework for certifying small-signal stability in AC grids using frequency-domain quadratic constraints on individual grid subsystem…

Decentralised Plug-and-Play Stability Conditions for AC Grids-Part I
Liam Hallinan, Ioannis Lestas
The rise of renewable generation in AC power systems calls for small-signal stability assessment methods that do not rely on centralised, system-wide models. In this two-part paper…

Unstable Poles Arising in AC Power Grid Subsystem Representations
Liam Hallinan, Ioannis Lestas
Recent small-signal stability studies of AC grids have shifted towards analysing power systems as interconnections of subsystems and leveraging their input-output properties to der…
