Rapid Admittance Measurement of Power Converters Using Double-PLL Grid-following Inverters
IEEE Transactions on Power Delivery, 2023 <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
2022 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2022 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 ...

-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.
