Stability Control for Grid-Connected Inverters Based on Hybrid-Mode of Grid-Following and Grid-Forming

IEEE transactions on industrial electronics (1982. Print)
Grid-connected inverters (GCIs) operating in grid-following (GFL) mode may be unstable under weak grids with low short-circuit ratio (SCR). Improved GFL controls enhance the small-signal stability of GCIs under weak grids but result in a decrease in ...

Evaluating the Equivalent Inertia of Grid-Following and Grid-Forming Inverter-Based Resources

IEEE transactions on energy conversion
The increasing prevalence of inverter-based resources (IBRs) is creating changes in the dynamic behaviors of power systems. Depending on the type of control, IBRs can exhibit time-varying inertial support following disturbances, even when using a fixed ...

A Constant Damping Phase-Locked Loop for Enhancing Transient Stability of Grid-Following Inverter

IEEE Transactions on Industrial Informatics
When a large grid disturbance occurs, the grid-following inverter is prone to cause transient instability due to the weak damping or negative damping induced by a synchronous reference frame phase-locked loop.

Grid-Following Inverters and Synchronous Condensers: A Grid-Forming Pair?

2020 Clemson University Power Systems Conference (PSC), 2020
As power systems across the globe continue to achieve higher instantaneous penetrations of power electronic converter-interfaced renewable sources, the stability of these power systems is challenged because of the removal of synchronous machines, from which stability is traditionally derived.

Analytical Design of Contributions of Grid-Forming and Grid-Following Inverters to Frequency Stability

IEEE Transactions on Power Systems
Most of the new renewable generation in power systems is connected through Grid-Following inverters (GFL). The accompanying decline of fossil-fuelled synchronous generation reduces the grid inertia. As these two trends progress, instabilities become more
