Unified Virtual Oscillator Control for Grid-Forming and Grid-Following Converters [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021 A unified virtual oscillator controller (uVOC) is proposed, which enables a unified analysis, design, and implementation framework for both grid-forming (GFM) and grid-following (GFL) voltage source converters (VSCs). Oscillator based GFM controllers, such as dispatchable virtual oscillator control (dVOC), offer rigorous analytical framework with ...

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.

Grid‐forming requirements based on stability assessment for 100% converter‐based Irish power system
IET Renewable Power Generation, 2022 The fault response of a 100% converter‐based system can be significantly different to that of a synchronous generator‐based system, considering the lower capacity headroom, but flexible control capability, of power electronic converters.

Impact of Digital Control Delay on Stability of Grid-Following Converters
2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022 In a digital controlled system, the delay is inevitable. It will change the phase-frequency characteristics of the system, which will affect the stability. This paper analyzes the configuration of the grid-following converter and builds its small-signal model in detail.
