Revisiting Grid-Forming and Grid-Following Inverters: A Duality Theory [PDF]

IEEE Transactions on Power Systems, 2022
Power electronic converters for integrating renewable energy resources into power systems can be divided into grid-forming and grid-following inverters. They possess certain similarities, but several important differences, which means that the relationship between them is quite subtle and sometimes obscure.

Linear Parameter-Varying Control of a Power-Synchronized Grid-Following Inverter [PDF]

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
This paper proposes a Linear Parameter-Varying loop-shaping controller for a power-synchronized grid-following inverter (PSGFLI). This control strategy regulates the inverter output active and reactive power at the terminal instead of the point of connection and does not require a phase-locked loop (PLL) for extracting the voltage phase angle.

Transient Stability of Paralleled Virtual Synchronous Generator and Grid-following Inverter

IEEE Transactions on Smart Grid, 2022
The majority of inverter-based resources (IBRs) currently operate as grid-following inverters (GFLIs). These inverters exhibit certain stability issues when integrated in low-strength areas of the grid. To enhance the grid strength in a GFLI-dominant area, virtual synchronous generators (VSGs) are installed.
