Abstract:
1. A power control apparatus for a cluster system, comprising: a cluster including a plurality of nodes, each equipped with a battery; and a power control unit connected to the cluster over a network and configured to monitor power management information and performance information of the cluster and to set a power capping threshold based on the monitored power management information and performance information of the cluster, thus enabling power of the cluster to be limited by turning on and off the batteries when power of the cluster system increases up to the power capping threshold, wherein each node of the cluster is connected to a power supply unit separate from the battery and the power of the cluster is supplied by the separate power supply unit or the battery, wherein the determining the power cap value comprises: setting a maximum power capping threshold and a minimum power capping threshold for the cluster system and separately setting an operating power cap value (driving point) that enables an operation to be performed between the maximum power capping threshold and the minimum power capping threshold; and increasing the operating power cap value up to a preset power capping threshold when the cluster system executes the power capping mode above the operating power cap value, but the power of the cluster system cannot be decreased below the power capping threshold due to a load of the cluster system.
