  "textContent": "A method of controlling a grid-connected voltage source converter, VSC, using power-synchronisation control, wherein the method includes: determining an active power control error, determining a VSC phase angle based on an integration of a sum including a scaled active power control error and a scaled imaginary part of a voltage of common coupling, determining a damping component based on a virtual damping resistance, a VSC current vector and a reference current vector for the VSC current vector, determining a voltage vector based on a VSC voltage magnitude and the damping component, transforming the voltage vector to a current vector, comparing a magnitude of the current vector with a maximum threshold current value, and in case the magnitude of the current vector is greater than the maximum threshold current value: reducing the magnitude of the current vector to a value below the maximum threshold current value to obtain a limited current vector, transforming the limited current vector to a limited voltage vector, controlling the VSC based on the VSC phase angle and the limited voltage vector, multiplying an imaginary part of a voltage of common coupling with a gain to obtain a scaled imaginary part of voltage of common coupling.",
