Sensitivity Analysis and Small-Signal Stability of Grid Following Converters
TecnoLógicas, 2022 This article presents a small-signal study, based on a sensitivity analysis, of a voltage source converter (VSC) operating as a grid-following device. This type of operation is standard for integrating distributed energy resources directly into a primary

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

Synchronous Fault Compensator for Voltage Sensorless Grid-Following Power Converters
2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2021 During the last decade, the penetration of grid-connected RES systems has been in constant increase, forcing those systems interfaced to the electrical grid to improve and design new advanced controllers to maintain the power converter under control. The most extended control for grid-tied inverters is the so-called grid-following control.

An Alternative Control Structure for Grid-Following Converters of Inverter-Based Resources
IEEE Open Access Journal of Power and Energy, 2023 In this paper, an alternative control structure of grid-following control is proposed and applied in inverter-based resources (IBRs). An IBR’s grid-following control normally employs Power/Voltage (P/V) control strategy to control the output real ...

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 ...
