Power decoupling control method and system for virtual synchronous generator based on voltage feedforward compensation

The invention belongs to the technical field of power electronic device control, and relates to a power decoupling control method and system for a virtual synchronous generator based on voltage feedforward compensation. The method comprises the steps of firstly, acquiring output power Pvsg and Qvsg of the virtual synchronous generator; giving a reactive power reference value Qref, subtracting thereactive power Qvsg output by the virtual synchronous generator from the reactive power reference value Qref to obtain d-axis initial reference voltage V to be 0 at the same time, then presetting voltage feedforward equivalent inductive reactance Xv, and generating feedforward voltage Xviod; and obtaining a voltage control loop reference instruction V according to the d-axis initial reference voltage V to obtai
