PROBLEM TO BE SOLVED: To synchronize a control time between a plurality of power controllers connected via a ring network.SOLUTION: An energy storage system synchronizing method comprises, when a first signal is received by a plurality of slave power controllers, measuring a reception time at which each of the plurality of slave power controllers receives the first signal; and receiving, by the plurality of salve power controllers, a second signal for controlling synchronization of the plurality of slave power controllers on the basis of the reception time. The method has an advantage of allowing an accurate control in consideration of a time delay of a network.SELECTED DRAWING: Figure 3 |
