The invention discloses an energy storage control method for suppressing low frequency oscillation of a wind farm based on dynamic consistency damping. The method comprises: controlling a fundamentalcurrent of each energy storage subsystem by calculating a fundamental current of the energy storage subsystem; performing low-frequency oscillation detection on each energy storage subsystem to obtaina low-frequency oscillation point of the energy storage subsystem; and setting a virtual damping at the low-frequency oscillation point, wherein the virtual damping is a low-frequency damping of dynamic consistency, and suppressing the oscillation of an energy storage system. The method enables an energy storage cluster as a system global oscillation suppressor by the damping control of the dynamic consistency algorithm, fully exerts the function of each energy storage subsystem to suppress the oscillation, and avoids the oscillation intensification due to the inconsistent damping of the energy storage subsystems. Each energy storage subsystem only communicates with neighboring individuals, greatly reducing the communication traffic and enhancing the reliability.
