The method comprises calculating a converter voltage reference for the VSC based at least on a reference current, calculating a phase-angle of an electromotive force (EMF) voltage vector of the VSC based on at least an active power reference, calculating a voltage amplitude of the EMF voltage vector based on at least a grid voltage at the PCC and a grid voltage reference, calculating the reference current by feeding the EMF voltage vector through a virtual admittance, and limiting the active power reference and the voltage amplitude based at least on a maximum allowed current threshold associated with operation of the VSC such that the reference current does not exceed said maximum allowed current threshold.",
