Comparative Impedance Characteristic Analysis of Grid‐Following and Grid‐Forming Inverters
IET Renewable Power Generation, 2023 This paper comprehensively analyses the impedance characteristics of grid‐following (GFL) and grid‐forming (GFM) inverters at around synchronous frequency areas considering various operating and grid connection conditions and control settings.

External Inertia Emulation Controller for Grid-Following Power Converter [PDF]
IEEE Transactions on Industry Applications, 2021 The advent of renewable energy has posed difficulties in the operation of power systems whose net inertia is becoming critically low. To face such challenges, grid-forming power has been one of the potential solutions pursued by the industry and research community. Although promising, grid-forming power converters are still immature for mass deployment

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.

Modelling of grid-following current-controlled VSC
Journal of Physics: Conference Series, 2023 Abstract The voltage sourced converter (VSC) is a basic element in the grid connected solar-PV system that used in converting the DC-generated power from the solar-PV to AC power compatible with the utility grid. In this paper, a grid connected, three phase, two level VSC model and its control technique are simulated.

Demystifying inertial specifications; supporting the inclusion of grid‐followers
IET Renewable Power Generation, 2023 Abstract Inertial response from grid‐followers (GFLs) is deemed to be “synthetic” due to a slow response. In contrast, grid‐forming (GFM) inertial response is deemed to be faster and therefore “true” and more useful for frequency stability.

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
