Multiple distribution static synchronous compensators for distribution feeder voltage support

IET Generation, Transmission and Distribution, 2012
The potential of multiple distribution static synchronous compensators (DSTATCOMs) to improve the voltage profile of radial distribution networks has been reported in the literature by few authors. However, the operation of multiple DSTATCOMs across a distribution feeder may introduce control interactions and/or voltage instability. This study proposes

Mitigation of voltage sags in distribution line system using static VAR compensator and static synchronous compensator [PDF]

Journal of Physics: Conference Series, 2022
Abstract Voltage sag is one of the power quality disturbances most frequently by customers because it can cause economic loss for the customers especially industries and commercial customers. The main source of voltage sags are faults in transmission and distribution beside two others namely motor large starting and transformer ...
