An Inverter-Controlled Series Compensator (ICSC) (9) has a reactive impedance element (11, 21) connected in series with the line (3) of an ac transmission system (1) and an inverter (13) connected in parallel with the reactive impedance element (11, 21) to control the voltage across, and therefore the current through the reactive impedance element (11, 21) 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 (27) with a source/sink (29) of real power, the ICSC (9) is further capable of adjusting series impedance. The reactive impedance element (11, 21) can be either a capacitive element (11) or an inductive element (21) depending upon whether there is a need for capacitive or inductive compensation.
