Dynamic voltage restores (DVRs) are usually used to mitigate the effect of voltage sag and guarantee sufficient power supply for sensitive loads. However, three-phase voltage cannot be compensated to the desired balance voltage under unbalanced three

To address the issue of uncertainty in the occurrence time of voltage sags in power grids, which affects power quality, a voltage state prediction method based on LSTM neural networks is proposed for predicting voltage states. For the problem of quic

Though we have many power quality issues, voltage sag, interruption and swell are considered to be very important ones as it occurs very frequently and affects the sensitive loads adversely. Though many topologies of DVR are presented in the literatu
