Abstract

The paper discusses the operating principles and control characteristics of an interline voltage controller (IVOLCON) for voltage regulation in parallel distribution feeders. The IVOLCON consists of two shunt voltage source converters (VSCs) connected to different feeders through a common DC link. The main aim of the IVOLCON is to control the two PCC (point of common coupling) bus voltages of the two feeders to prespecified magnitudes with mutual support by providing bi-directional power flow through the DC link. The phase angles of the PCC bus voltages are obtained such that the voltage across the common DC link remains constant. The efficacy of the proposed configuration has been verified through simulation studies using PSCAD/EMTDC for system disturbances like deep voltage sags, swells and feeder outage.
