Delay-Based Phase-Locked Loop Parameters Design Based on Stability Region of Grid-Connected Single-Phase Inverter Under Grid Voltage Sags

IEEE transactions on industrial electronics (1982. Print), 2022
For the grid-connected inverter, grid voltage sag can be a typical phenomenon. From the prospective of safe and robust operation, the inverter should be stable when the grid voltage sag (or large disturbance) occurs.

Improved Premium Model of Voltage Sag Insurance Based on Voltage Sag Risk

IEEE Transactions on Power Delivery, 2022
Voltage sag insurance (VSI) is an effective measure to reduce the voltage sag loss and risk for enterprises with insufficient mitigation confidence or economic ability. However, due to the lack of understanding of voltage sag risk (VSR), it is difficult for power utilities to identify the enterprises with VSI demands, and it is also unable to realize ...

Stability Analysis and Enhancement of Type-4 Wind Turbines Connected to Very Weak Grids Under Severe Voltage Sags

IEEE transactions on energy conversion, 2019
Modern grid codes require wind turbines (WTs), e.g., type-4 WTs, to have low voltage ride-through (LVRT) capability, and recently, great attention has been attracted on the stability issues of WTs during the period of the LVRT.

Voltage Sag Studies in Distribution Networks—Part II: Voltage Sag Assessment

IEEE Transactions on Power Delivery, 2006
This paper is the second part of a joint paper aimed at predicting the voltage sag performance of distribution networks by estimating voltage sag indices. This part explores the characteristics of voltage sags caused by faults in a distribution network considering the effect of the protective devices installed in the network.
