    Abstract: Provided a cluster control system which controls energy storage systems (ESSs) within the cluster and a method for distributing energy among the ESSs in the cluster. The control system includes: ESSs which are provided in a consumption facility or a building and which supply power to respective loads in the facility or building; and a cluster control server distributing energy between the ESSs in the cluster based on an energy level with respect to stored energy amounts of the ESSs. Energy in a cluster in which a plurality of distributed ESSs are grouped is efficiently distributed to a predetermined zone partitioned by the cluster such that the cluster may mange the energy independent of supply of the energy from an external power system.
