The present invention relates to a fluctuation tracking control method for commercial power of an elevator energy storage apparatus, and provides a method for controlling the elevator energy storage apparatus, comprising: a first voltage detecting unit which measures charging and discharging voltage of the storage means storing electric energy generated in regenerative braking of a motor for the elevator; a second voltage detecting unit which detects a secondary voltage of a converter for operating the motor for the elevator; a DC-DC converter which switches charging and discharging into the storage means so as to store regenerative power in the regenerative braking of the motor for the elevator into the storage means and output the charged power of the storage means when the motor for the elevator is operated; and a control unit which controls the DC-DC converter according to the secondary voltage of the converter and the commercial power voltage fluctuation according to operations of the elevator. According to the present invention, the energy storage apparatus applied in the elevator controls the secondary voltage of the converter so as to store and discharge energy according to the secondary voltage of the converter and the commercial power voltage fluctuation, and thereby, increasing availability of the elevator such that the present invention has advantages of being able to increase energy reduction effects when using the elevator and stably performing management of the elevator.
