A New Method for Fault Location in Distribution Networks Based on Voltage Sag Measurements
IEEE Transactions on Power Delivery, 2021This paper presents an innovative method for fault location in distribution networks based on classical circuit analyses. Two synchronized and few nonsynchronized pre- and during-fault voltages are required at few buses along with the impedancematrix.

Improved Premium Model of Voltage Sag Insurance Based on Voltage Sag Risk
IEEE Transactions on Power Delivery, 2022Voltage 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 ...
