Abstract: A power transmission network including a single-phase or multi-phase AC electrical system, a converter including an AC terminal, a point of common coupling, a phase reactance connecting the common coupling to each AC terminal, and a transmission medium to interconnect the common coupling and the electrical system. The network includes a controller to: process the voltage and current at the common coupling to compute a state vector; derive a converter demand by combining the state vector with control parameters, including the capacitance of the power transmission medium presented at the common coupling and the impedance of the phase reactance; and operate the converter according to demand controlling the voltage at each terminal and/or the common coupling to inhibit any perturbation in the converter voltage from a target converter voltage or range resulting from the interaction between the capacitance of the power transmission medium and the impedance of the phase reactance.
