Tuning Method of a Grid-Following Converter for the Extremely-Weak-Grid Connection [PDF]

IEEE Transactions on Power Systems, 2022
This paper proves that a grid-following converter can stably connect to a weak grid even short-circuit ratio (SCR) is 1. Root instability causes of this grid-following control are identified including fast control response, insufficient damping, and slow voltage support.

Synchronization Stability Enhancement of Grid-Following Converter Under Inductive Power Grid

IEEE Transactions on Energy Conversion, 2023
The loss of synchronization (LOS) is a main issue for dynamic behavior of grid-following converter (GFC) under inductive power grid. This letter reveals the underlying mechanism of insufficient damping or even negative damping during grid disturbance, and analyzes how the initial speed of angle-difference between PLL output and grid voltage affects the

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 ...
