The invention discloses a broadband suppression method, device and equipment for a wind power grid-connected system and a storage medium, and the method comprises the steps: deducing an equivalent impedance model of the wind power generator grid-connected system through analyzing a DC bus, a grid-side converter and a control system of the wind power generator grid-connected system; performing positive and negative sequence component decomposition on the equivalent impedance model, and performing stability analysis on the wind driven generator grid-connected system according to frequency characteristics of equivalent resistance and frequency characteristics of equivalent reactance; and based on the equivalent impedance model, establishing a fitness function of control parameters in combination with a particle swarm algorithm, and performing broadband oscillation suppression based on optimal control parameters determined by optimization of the fitness function. Meanwhile, the influence of control parameters on
