External Inertia Emulation Controller for Grid-Following Power Converter [PDF]
IEEE Transactions on Industry Applications, 2021 The advent of renewable energy has posed difficulties in the operation of power systems whose net inertia is becoming critically low. To face such challenges, grid-forming power has been one of the potential solutions pursued by the industry and research community. Although promising, grid-forming power converters are still immature for mass deployment

Tuning Method of a Grid-Following Converter for the Extremely-Weak-Grid Connection [PDF]
IEEE Transactions on Power Systems, 2022 This paper proves that a grid-following converter can stably connect to a weak grid even short-circuit ratio (SCR) is 1. Root instability causes of this grid-following control are identified including fast control response, insufficient damping, and slow voltage support.

Synchronization Stability Enhancement of Grid-Following Converter Under Inductive Power Grid
IEEE Transactions on Energy Conversion, 2023 The loss of synchronization (LOS) is a main issue for dynamic behavior of grid-following converter (GFC) under inductive power grid. This letter reveals the underlying mechanism of insufficient damping or even negative damping during grid disturbance, and analyzes how the initial speed of angle-difference between PLL output and grid voltage affects the

Oscillation Suppression of Grid-Following Converters by Grid-Forming Converters with Adaptive Droop Control [PDF]
EnergiesThe high penetration of renewable energy sources (RESs) and power electronics devices has led to a continuous decline in power system stability. Due to the instability of grid-following converters (GFLCs) in weak grids, the grid-forming converters (GFMCs) have gained widespread attention featuring their flexible frequency and voltage regulation ...

Large-Signal Stability Analysis of Grid-Following Converters Considering the Behavior of Grid-Forming Converters [PDF]
International Journal of Circuit Theory and ApplicationsABSTRACTThe increasing penetration of renewable energy challenges single‐converter systems to simultaneously provide transient support and rapid response. Hybrid microgrids integrating grid‐forming (GFM) and grid‐following (GFL) converters are thus essential for dual‐high power systems.

Synchronous Fault Compensator for Voltage Sensorless Grid-Following Power Converters
2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2021 During the last decade, the penetration of grid-connected RES systems has been in constant increase, forcing those systems interfaced to the electrical grid to improve and design new advanced controllers to maintain the power converter under control. The most extended control for grid-tied inverters is the so-called grid-following control.
