Impedance-Based Analysis of Grid-Synchronization Stability for Three-Phase Paralleled Converters (2014, background): “Although impedance-based analysis is also proposed to study the stability of grid-connected inverter systems [26]–[29], such analysis is not reported to analyze the synchronization stability issue between parallel connected VSCs and the grid as discussed above.”
Small-Signal Stability Assessment of Power Electronics Based Power Systems: A Discussion of Impedance- and Eigenvalue-Based Methods (2017, background): “Many researchers have focused on the analysis of the stability of a grid-tied inverter at interfacing point connecting to the grid, either in the ac side by sequence domain impedance by checking the Nyquist stability criterion on the positive and the negative sequence impedance ratio [17]– [21] and ”
