Summary: | The invention provides a virtual inertia self-adaptive control method for a wind storage all-in-one machine. The method comprises the following steps: obtaining a back electromotive force of a wind driven generator through a state observer; the phase-locked loop obtains an angular frequency estimation value of the back electromotive force through the back electromotive force; obtaining a mechanical rotating speed estimated value according to the angular frequency estimated value; obtaining a corrected rotating speed according to the estimated value of the mechanical rotating speed and the measured value of the mechanical rotating speed; correcting the virtual inertia by using the corrected rotating speed and the measured charge state of the stored energy to obtain a corrected virtual inertia; and controlling the frequency response change according to the corrected virtual inertia and the corrected rotating speed. According to the virtual inertia adaptive control method for the wind storage all-in-one machine, |
