A method of controlling a power converter, connected to an electrical grid, to mimic a synchronous generator, by: determining a frequency control error with respect to a setpoint and actual frequency of the grid, determining an input power to an inertia model of a synchronous generator based on the frequency control error, regulating by means of the input power a rotational frequency of the inertia model, determining a voltage control error with respect to a setpoint and actual voltage, determining an exciter parameter of a synchronous generator model based on the voltage control error, regulating by means of the exciter parameter an output voltage of the synchronous generator model, adjusting the rotational frequency or a phase angle obtained from the rotational frequency, and the output voltage based on a virtual impedance of a stator of the synchronous generator model, and controlling the power converter based on the adjusted rotational frequency or the adjusted phase angle and on the adjusted output voltage.
