Adaptive Control of Grid-Following Inverter-Based Resources Under Low Network Short Circuit Ratio

IEEE transactions on industry applications
The stability and dynamic response of inverter-based resources are greatly influenced by uncertain grid parameters. The grid short circuit ratio (SCR) serves as a standard metric for assessing the strength of the network at any location within the ...

Understanding a Type of Forced Oscillation in Grid-Forming and Grid-Following Inverter Connected Systems

IEEE transactions on power electronics
This article investigates a novel oscillation phenomenon in systems with grid-forming (GFM) and grid-following (GFL) inverters. Unlike previous studies that primarily focus on small-signal stability, this work explores forced oscillations (FOs), where ...

Nonlinear Backstepping Control of Grid-Forming Converters in Presence of Grid-Following Converters and Synchronous Generators

IEEE Transactions on Power Systems
Grids in near future are going to host synchronous generators (SGs), legacy grid-following converters (GFLCs), and relatively new grid-forming converters (GFCs), where the latter two technologies support converter-interfaced generations.

Synchronization Stability Analysis and Parameter Design of Grid-Following Inverters Considering the Interactions of Current Control and Phase-Locked Loop

IEEE Journal of Emerging and Selected Topics in Power Electronics
For grid-following inverters (GFLIs), grid voltage sag can induce the loss of synchronization (LOS) under weak grids. Numerous studies have discussed the synchronization instability dominated by phase-locked loops (PLLs). However, since the inverter is a
