Transformer‐less unified power flow controller in medium voltage distribution networks

A transformer-less unified power flow controller (UPFC) is a electronic device consisting of series and shunt voltage source converters (VSCs) that are not connected to common DC bus. It can control in medium (MV) distribution networks without the need for interfacing transformers. Hence there significant reduction size cost compared conventional UPFC. This paper investigates operating range UPFC an MV network required ratings converters. The results showed able provide active using partially rated However, its ability reactive limited by current analysis was verified software simulation hardware experiment.
