Abstract
An Inverter-Controller Series Compensator (ICSC) has a reactive impedance element connected in series with the line of an ac transmission system and an inverter connected in parallel with the reactive impedance element to control the voltage across, and therefore the current through, the reactive impedance element to provide a continuously adjustable series reactance for power flow control, series voltage regulation, oscillation damping and stability enhancement, as needed. By providing the inverter with a source/sink of real power, the ICSC is further capable of adjusting series impedance. The reactive impedance element can be either a capacitive element or an inductive element depending upon whether there is a need for capacitive or inductive compensation.
