An Overview of Assessment Methods for Synchronization Stability of Grid-Connected Converters Under Severe Symmetrical Grid Faults (2019, unknown): “Furthermore, as pointed out in [51], [52], an increasing proportional gain of the PLL will increase the frequency where the phase characteristics cross − 180 ◦ which degrades the stability.”
Impedance-Based Analysis of DC-Link Voltage Dynamics in Voltage-Source Converters (2019, methodology): “Hence, the impedance matrix is used for the stability analysis [21], [23], which indicates that the negative impedance introduced by the dc-link voltage control is due to the constant power load behavior during the rectifier operation mode of VSCs.”
Analysis and Performance Enhancement of Vector-Controlled VSC in HVDC Links Connected to Very Weak Grids (2017, background): “PLLs have been investigated for a long time, and many different types have been introduced [11]–[14].”
The Small-Signal Stability Analysis of the Droop-Controlled Converter in Electromagnetic Timescale (2019, background): “Considering the characteristics of the converters controlled by droop controller with PLL, the PLL would also become a main factor to result in an instable phenomenon in the converterbased ac microgrids [1], [3], [31].”
Small-Signal Stability Assessment of Power Electronics Based Power Systems: A Discussion of Impedance- and Eigenvalue-Based Methods (2017, background): “Hence, the stability of the system can be determined by checking the GNC on the minor-loop gain [37], G(s)H(s) = Zs(s)Z−1l (s) = [ GHdd(s) GHdq(s) GHqd(s) GHqq(s) ] .”
A Modified Sequence-Domain Impedance Definition and Its Equivalence to the dq-Domain Impedance Definition for the Stability Analysis of AC Power Electronic Systems (2016, background): “[11], where the coupling related to the first four bullet-points can be identified.”
AC Stability Analysis and dq Frame Impedance Specifications in Power-Electronics-Based Distributed Power Systems (2017, methodology): “frequency response of Yqq [15]–[19], it is recommended then that impedance specifications be issued for both d- and q-axes in the dq-domain.”
