The Performance of a Three-Phase Induction Motor under and over Unbalance Voltage [PDF]
Tikrit Journal of Engineering Sciences, 2021 Voltage unbalance is an adverse global phenomenon impacting three-phase induction motor output. Three-phase source voltage may become imbalanced in a variety of respects, while a balanced system preserves stable voltage magnitude and angles in ...

Synchronizing a synchronverter to an unbalanced power grid using sequence component decomposition
Nonlinear Engineering, 2022 The synchronverter is a device used in some microgrids to perform self-synchronization and represent the behavior of a synchronous machine. However, the original control has been proposed for balanced networks, which is not present in all distribution ...
