Wideband Dissipativity Enhancement of Grid-Following Inverters Using Virtual Element Design [PDF]
Dissipativity provides a convenient approach to predict system stability, which explains the induced resonances from the perspective of damping. To mitigate potential resonances and improve stability, this work presents a design method to enhance the dissipativity of grid-following inverters over a wide frequency range.

Power hardware-in-the-loop testing for multiple inverters with virtual inertia controls
Virtual inertia (VI) control schemes implemented in inverter-based resources (IBRs) present a promising solution for mitigating the absence of inertial response in power systems after the decommissioning of synchronous generators (SGs).

Rapid Admittance Measurement of Power Converters Using Double-PLL Grid-following Inverters
<p>As power systems undergo a transformation with increasing inverter-based resources (IBRs), understanding the stability and dynamics of IBR-dominated systems becomes imperative. Though analytical models offer insights into these changes, intellectual property constraints introduce a challenge due to the black-box nature of IBRs, highlighting ...

Comparative Analysis of Transient Stability of Grid-Forming and Grid-Following Inverters
The increasing dominance of renewable energy sources in the modern power grids, leads to the installation of power electronic inverters as they are required to interface these DC and variable frequency sources to the grid. These inverters can provide additional flexibility to the control of the power grid and are distinguished into grid-forming (GFM ...

Performance evaluation of secondary control policies with respect to digital communications properties in inverter-based islanded microgrids [PDF]
A key challenge for inverted-based microgrids working in islanded mode is to maintain their own frequency and voltage to a certain reference values while regulating the active and reactive power among distributed generators and loads.

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