A convex formulation for voltage unbalance compensation problem on hybrid microgrids
Revista Principia, 2019 Voltage unbalance is a power quality condition that arises due to the presence of unbalanced single-phase loads. The presence of voltage unbalances affects negatively a series of sensible equipment and, therefore, is undesirable.

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 ...

Voltage Unbalance Compensation in Distribution Feeders Using Soft Open Points
Journal of Modern Power Systems and Clean Energy, 2022 Soft open points (SOPs) are power electronic devices that may replace conventional normally-open points in distribution networks. They can be used for active power flow control, reactive power compensation, fault isolation, and service restoration ...
