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.

Double-Synchronous-Reference-Frame-Based Power-Synchronized PLL-Less Grid-Following Inverters for Unbalanced Grid Faults

IEEE Open Journal of Power Electronics, 2023
This article proposes a double-synchronous-reference-frame-based power-synchronized grid-following inverter (DS-PSGFLI). In contrast to existing types of phase-locked-loop (PLL)-based grid-following inverters (GFLIs) and PLL-less power-synchronized GFLIs

Coordinated Frequency and Voltage Regulation of Grid-Following and Grid-Forming Inverters

CoRR, 2020
In a purely inverter-based microgrid, both grid-forming (GFM) and grid-following (GFL) inverters will have a crucial role to play in frequency/voltage regulation and maintaining power sharing through their grid support capabilities. Consequently, the coordination between these two technologies becomes increasingly important for optimal system ...

Active Power Coordination for a Large Population of Grid-Forming and Grid-Following Inverters Based on Mean Field Games Theory

IEEE Access, 2023
In a grid with a high proportion of renewable energy, the coordinated control between grid-forming (GFM) and grid-following (GFL) inverters becomes crucial for maintaining aspects such as frequency and voltage regulation.
