CONTROLLER AND METHOD FOR CONTROLLING ONE OR MORE COMPONENTS OF A POWER SYSTEM

Controller and method for controlling one or more components of a power system. The power system includes an AC power node connected to an AC system. The controller is configured to determine a first phase angle between a first voltage of the AC power node and a current of the AC power node; determine, based on the first angle, a second angle between the first voltage of the AC power node and a second voltage of the AC system; and output data indicative of at least the second angle for controlling the one or more components of the power system.
