Interline power flow controller

Abstract

A power flow controller includes a voltage source converter including an alternating current (AC) voltage output configured to be simultaneously coupled to a first power transmission line and a second power transmission line. The voltage source converter is configured to generate, at the AC voltage output, AC voltage to be injected into the first power transmission line with additive polarity and into the second power transmission line with subtractive polarity to perform complementary compensation on the first and second power transmission lines. The power flow controller may further include a controller coupled to the voltage source converter and configured to control the phase angle of the AC voltage relative to at least one of the phase angles of the first and second power transmission line currents.
