Comprehensive Power Losses Model for Electronic Power Transformer
IEEE Access, 2018 The electronic power transformer (EPT) has higher power losses than the conventional transformer. However, the EPT can correct the power factor, compensate the unbalanced current, and reduce the line power losses in the distribution network.

Improved control of virtual synchronous generator under unbalance of grid voltage
Energy Reports, 2023 Asymmetric faults in the power grid will lead to unbalanced grid voltage. When the traditional VSG control operates under unbalanced grid voltage, the output current will be unbalanced, resulting in output power oscillation.

Unbalanced current-based tariff
CIRED - Open Access Proceedings Journal, 2017 The voltage and current unbalances are serious power quality problems with interaction on each other and mainly affecting low-voltage electricity distribution three-phase systems. In a three-phase system, the current unbalance is due to load unbalance, while it is considered as the main cause of voltage unbalance.
