Apparatus, method and system for controlling power supply

摘要: A method in a power system infrastructure for controlling power supplied to a plurality of data processing machines, wherein the power system infrastructure comprises a plurality of power supply units, comprises receiving a plurality of power demand values, wherein the power demand values are associated with a respective plurality of data processing instances to be executed on the plurality of data processing machines. The method comprises estimating a total power demand value based on the received power demand values. The method comprises controlling the power system infrastructure to provide power to the plurality of data processing machines based on the estimated total power demand value.
