description The invention discloses a grid-connected inverter impedance remolding oscillation suppression method and device and a storage medium, through parallel connection of a proportional link to a disturbance observation branch of a linear extended state observer in an active disturbance rejection controller, the observation speed of the observer to a disturbance signal is enhanced, the damping ratio coefficient of the extended state observer is improved, and the stability of the disturbance signal is improved. The middle-frequency-band positive damping characteristic of the output impedance of the grid-connected inverter based on active disturbance rejection control is improved; by adding a low-pass filter to an input signal branch of the extended state observer, the suppression capability of the extended state observer on high-frequency noise is improved. The extended state observer not only retains the control performance advantage of the active-disturbance-rejection control technology, but also further improves
