Abstract
A method of controlling a grid-connected voltage source converter, VSC, using power-synchronization control, wherein the method includes: determining a VSC current vector (i) based on a VSC phase angle (θ) which is determined based on an integration of a power control error, determining an active power producing current component (i) of a reference current vector (i) based on an active power reference (P) for the VSC, determining the reference current vector (i) based on the active power producing current component (i), determining a damping component based on a virtual damping resistance (R), the reference current vector (i) and the VSC current vector (i), determining a voltage vector (v) based on a VSC voltage magnitude (V) and the damping component, and controlling the VSC based on the voltage vector (v).
