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 ...

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.

Grid–Following DVI–Based Converter Operating in Weak Grids for Enhancing Frequency Stability [PDF]
IEEE Transactions on Power Delivery, 2022 Inertia requirement is the paramount challenge in future power systems with a significant share of renewable energy generators. A promising solution to this issue is applying Distributed Virtual Inertia (DVI) concept, i.e. releasing energy preserved in the dc-link capacitors of employed power converters in the grid following a frequency disturbance ...

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.
