Coordinated Control Strategy for Current Inner Loops to Enhance Transient Synchronization Stability During LVRT Under Symmetrical Faults [PDF]
Dianli jianshe[Objective] Grid-following converters （GFL） are widely employed in renewable energy grid integration systems. When grid faults cause voltage sags，the system enters a low voltage ride-through （LVRT） process.

Transient Stability of Paralleled Virtual Synchronous Generator and Grid-following Inverter
IEEE Transactions on Smart Grid, 2023 <p>The majority of inverter-based resources (IBRs) currently operate as grid-following inverters (GFLIs). These inverters exhibit certain stability issues when integrated in low-strength areas of the grid. To enhance the grid strength in a GFLI-dominant area, virtual synchronous generators (VSGs) are installed.

Interfacing Synchronous Machine Model Including Stator Transients With Network for Stability Studies
IEEE Transactions on Power Systems, 2023 A detailed multi-time scale model of synchronous machines (SM) with stator transients is necessary to capture the complex interactions in inverter-integrated power systems. The conventional detailed SM model, including stator transients is incompatible with that of the step-up transformer in the domain as both are modelled as current sources in series.

Synchronization and transient stability in power networks and non-uniform Kuramoto oscillators [PDF]
Proceedings of the 2010 American Control Conference, 2010 Motivated by recent interest for multi-agent systems and smart power grid architectures, we discuss the synchronization problem for the network-reduced model of a power system with non-trivial transfer conductances. Our key insight is to exploit the relationship between the power network model and a first-order model of coupled oscillators.
