  "textContent": "The present invention discloses an island microgrid system and an interactive oscillation suppression method and system therefor. A source-side virtual synchronous machine and a load-side virtual synchronous machine are combined to provide virtual inertia and damping. The present invention provides a d-axis inductive current feedforward control method and a d-axis voltage feedback control method to remodel impedances of VSGs, so as to reduce impedance amplitudes of the VSGs. Therefore, low-frequency interaction between the VSG and LVSM may be suppressed. The present invention may be used to solve interactive oscillation problems of an alternating-current island microgrid composed of a plurality of source-load virtual synchronous machines.",
