Performance analysis of grid-forming inverters in existing conformance testing

Energy Reports, 2022
Grid-forming (GFM) inverters are promising technologies in future power systems. Although the voltage-source characteristic of the GFM inverter has been validated to enhance the stabilities in low-inertia power systems, modifying protective function ...

-Synthesis-Based Generalized Robust Framework for Grid-Following and Grid-Forming Inverters

IEEE Transactions on Power Electronics, 2023
Grid-following and grid-forming inverters are integral components of microgrids and for integration of renewable energy sources with the grid. For grid following inverters, which need to emulate controllable current sources, a significant challenge is to address the large uncertainty of the grid impedance.

Asking for fast terminal voltage control in grid following plants could provide benefits of grid forming behavior

IET Generation, Transmission & Distribution, 2023
Conventional inverter based resource (IBR) plants generally have control loops with high bandwidth which enable them to maintain tight control of the active and reactive power injected by the IBR device into the grid.

Angular Stability Analysis of Parallel Connected Grid-following PV Inverters

2023 IEEE Texas Power and Energy Conference (TPEC), 2023
High penetration of distributed generators (DG) in modern power grids creates angle, voltage, and frequency instabilities. Most of the work in the literature has focused on small-signal stability analysis of single grid-connected inverters without thoroughly investigating their transient stability for large disturbances and interactions between ...

Impact of Inverter Controls in Small-Signal Stability of Power Systems Dominated by Inverter-Based Resources

IEEE Access
Initiatives to decarbonize contemporary power systems will lead to power systems dominated by inverter-based resources (IBR). These IBRs are broadly classified into grid-following (GFL) and grid-forming (GFM) inverter control regimes.

Contribution of Voltage Support Function to Virtual Inertia Control Performance of Inverter-Based Resource in Frequency Stability

Energies, 2021
Inertia reduction due to inverter-based resource (IBR) penetration deteriorates power system stability, which can be addressed using virtual inertia (VI) control. There are two types of implementation methods for VI control: grid-following (GFL) and grid-

Data-Driven Interarea Oscillation Analysis for a 100% IBR-Penetrated Power Grid

IEEE Open Access Journal of Power and Energy, 2023
In this research, a 100% inverter-based resource (IBR)-penetrated bulk power system (BPS) is examined for possible interarea oscillations. A testbed of a BPS constructed in PSCAD, with both grid-forming inverter (GFM)-based IBRs and grid-following
