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.

Enhancing microgrid resilience through integrated grid-forming and grid-following inverter strategies for solar PV battery control and fault ride-through [PDF]

Scientific Reports
This study investigates the integration of a Grid-Forming (GFM) Battery Energy Storage System (BESS) to enhance the stability of microgrids in the presence of high renewable energy penetration. The proposed GFM inverter, combined with BESS, significantly

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.

Oscillation Suppression of Grid-Following Converters by Grid-Forming Converters with Adaptive Droop Control

Energies
The high penetration of renewable energy sources (RESs) and power electronics devices has led to a continuous decline in power system stability. Due to the instability of grid-following converters (GFLCs) in weak grids, the grid-forming converters (GFMCs)

Small-Signal Stability of Hybrid Inverters with Grid-Following and Grid-Forming Controls

Energies
In the modern power grid, characterized by the increased penetration of power electronics and extensive utilization of renewable energy, inverter-based power plants play a pivotal role as the principal interface of renewable energy sources (RESs) and the

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

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.
