Abstract
The present invention relates to an ESS control device based on transient stability state and a method thereof, the an ESS control device based on transient stability state according to an embodiment of the present invention including an input unit receiving phase angle information from a power system; a calculation unit calculating a change rate in the phase angle of the power system using the phase angle information; a determination unit determining the transient stability state of the power system by comparing the change rate of the phase angle with a predetermined threshold; and a control unit performing control so that an energy storage system (ESS) installed in a power generation stage is switched to a charging mode according to the determination result.
