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.

Transient Stability of Paralleled Virtual Synchronous Generator and Grid-following Inverter
IEEE Transactions on Smart Grid, 2022 <p>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.
