1. A method of controlling a voltage source converter of a power supporting arrangement to act as a virtual synchronous machine, the method comprising:
obtaining a measured power level of the converter;
processing the measured power level using a differential equation of an angular velocity of the virtual synchronous machine in order to obtain a control contribution, wherein the differential equation is a swing equation defining a change in the angular velocity of the virtual synchronous machine over time comprising a moment of inertia term and a damping term;
providing a phase angle of a physical quantity used to control the converter based on the control contribution;
monitoring an ability of the converter to act as a virtual synchronous machine;
based on the monitoring, determining that the converter lacks the ability to act as a virtual synchronous machine; and
adjusting the control contribution by increasing the damping term and/or decreasing the moment of inertia term in response to determining that the converter lacks the ability to act as a virtual synchronous machine.
