IEEE Access, 2023 A novel, unified control design is proposed for software-defined inverters (SDIs) to operate in either grid-forming (GFM) or grid-following (GFL) mode in AC grids/microgrids and to switch between the two modes seamlessly.

Control of Grid-Following Inverters Under Unbalanced Grid Conditions
IEEE Transactions on Energy Conversion, 2020 This paper proposes a new control scheme to eliminate the 3rd harmonic in the output currents of grid-following inverters under unbalanced grid conditions. Unbalanced grids adversely affect the performance of grid-following inverters due to the oscillations appearing on the DC-link voltage with a frequency twice the line frequency.

Grid-Forming Converters: Control Approaches, Grid-Synchronization, and Future Trends—A Review
IEEE Open Journal of Industry Applications, 2021 In the last decade, the concept of grid-forming (GFM) converters has been introduced for microgrids and islanded power systems. Recently, the concept has been proposed for use in wider interconnected transmission networks, and several control structures ...

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 ...
