Impact of Voltage Sags on Electric-Vehicle Charger and Critical Voltage Sag Determination
IEEE Transactions on Power Delivery, 2016This letter investigates the impact of voltage sags on electric-vehicle chargers and presents a method to determine the minimum symmetrical voltage sag during and after which chargers can both be kept stable. The proposed method is based on the constraints of pulse-width modulation (PWM), electric circuits, and small-signal stability.

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 ...
