Transmission faults caused by recent wildfires in California have induced the disconnection of utility-scale converters in photovoltaic (PV) power plants. Postmortem investigations reported that tripping commands were caused by phase-locked loops (PLLs) and dc-side dynamics, which are typically unmodeled in classical transient stability studies. Since existing simulation packages rely on simplified models that neglect these dynamics, they have a limited capability to predict converter behavior… Expand
Nonlinear Modeling of Multi-Converter Systems Within DC-Link Timescale
TLDR
This paper first establishes a detailed nonlinear model of multiple VSC systems, and then, by using the singular perturbation technique, obtains a reduced-order non linear model within the DC-link timescale, showing a balance between computational accuracy and system complexity. Expand
Bulk Power System Dynamics with Varying Levels of Synchronous Generators and Grid-Forming Power Inverters

Transient Stability of Power Systems Integrated with VSCs
TLDR
This issue is investigated analytically and it is found that the converter output alters the power angle characteristics of generators; the converter's synchronization requirement limits the maximum power angle of the generator, which proves to be the leading cause of a new type of transient instability.

Resynchronization Analysis and Improvement of Grid-Connected VSCs During Grid Faults
TLDR
A variable structure PLL method with great simplicity is proposed to improve the resynchronization capability of VSCs during grid faults by removing PLL’s integral regulator, which causes the system operating point to enter negative damping zones and even reverse regulation zones, resulting in LOS.
