Abstract

A method and an apparatus for decoupling output power of an inverter are provided. The method comprises: obtaining voltage amplitude instruction E* and voltage phase instruction ¸* according to an output voltage and an output current of the inverter; obtaining an amplitude feedforward amount E ff and a phase feedforward amount ´ ff according to an amplitude U of a grid voltage of the power grid, an amplitude E of the output voltage of the inverter, and a phase difference ´ between the output voltage of the inverter and the grid voltage; obtaining a reference voltage amplitude E ref according to the voltage amplitude instruction E* and the amplitude feedforward amount E ff , and obtaining a reference voltage phase ¸ ref according to the voltage phase instruction ¸* and the phase feedforward amount ´ ff ; and regulating the output power of the inverter using the reference voltage amplitude E ref and the reference voltage phase ¸ ref .
