Comparative Analysis between Dynamic Voltage Restorer and PWM-Switched Autotransformer in Voltage Sag Mitigation

“…Dynamic voltage restorers (DVR), distribution static synchronized compensation, uninterruptible power supplies, flexible AC technology devices, and PWM-switched autotransformers are just a few of the mitigation tools currently being employed to lower voltage sag [10][11]. There are three devices, namely DVR with Park's transformation, DVR with artificial neural network (ANN) controller, and PWM-switched autotransformer with PI controller, are important for comparative research because they are some of the most commonly used voltage sag mitigation devices in power systems [12].…”
