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.

Stability analysis of grid-following converter considering DC side dynamics
电力工程技术DC side dynamics are ignored in most of the research on grid-connected converter, which is dealt as a constant voltage source. In this case, the analysis result of small-signal stability is affected to some extent.

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

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 ...

Sensitivity Analysis and Small-Signal Stability of Grid Following Converters
TecnoLógicas, 2022 This article presents a small-signal study, based on a sensitivity analysis, of a voltage source converter (VSC) operating as a grid-following device. This type of operation is standard for integrating distributed energy resources directly into a primary grid without considering the control over specific variables (e.g., voltage and frequency), thus ...
