11. A method for synchronverter power control comprising:
electrically coupling a synchronverter coupled with a power supply grid;
generating an active power Pf and a reactive power Qf through a power reference generator based on a terminal voltage measurement vector vt and a current measurement vector i from the synchronverter;
generating an electromotive force (EMF) vector e through a synchronverter control unit by processing the active power Pf and the reactive power Qf; and
regulating the current measurement vector i, wherein the regulating is based on the EMF vector e and the terminal voltage measurement vector vt and is configured to eliminate power oscillations and current harmonics in the synchronverter during unbalanced grid conditions and is performed through an active and reactive power control unit, connected between the synchronverter control unit and the synchronverter.
