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.

Grid-Following Inverter-Based Resource: Numerical State–Space Modeling
Sustainability, 2023 In the pursuit of a sustainable electric power system, the integration of renewable energy sources and distributed energy resources is gradually replacing traditional power generation. These new resources are integrated into the grid via inverters, which, despite their efficient performance, present dynamic challenges to the power grid when implemented

Transient Stability of Paralleled Virtual Synchronous Generator and Grid-following Inverter
IEEE Transactions on Smart Grid, 2023 <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.

Grid-Forming and Grid-Following Based Microgrid Inverters Control
Iraqi Journal for Electrical and Electronic Engineering, 2022 Microgrids (ℳ-grids) can be thought of as a small-scale electrical network comprised of a mix of Distributed Generation (DG) resources, storage devices, and a variety of load species. It provides communities with a stable, secure, and renewable energy supply in either off-grid (grid-forming) or on-grid (grid-following) mode.
