Abstract
A method for automatically determining whether power consumption devices can be powered up in a power consuming system having multiple power consumption devices to be powered up by one or several voltages among a set of voltages V1, V2 . . . Vm. The set of voltages are provided by multiple power supplies, wherein each power supply provides at least one voltage. The power consuming system also includes a control point for controlling the power supplied to the power consumption devices. The method includes determining a set of linear inequations linking each variable PV1, PV2 . . . PVm representing the power being consumed for each voltage, or combinations of several variables, to predetermined power limits PVC. Next, the real power value (P) requested for each voltage in order to power up each one of the first plurality of power consumption devices is determined. Subsequently, each real power value is divided by the number of power supplies (p) providing power for the associated voltage in order to determine the components of a power consumption vector (PC) for each power supply. Next, the variables PV1, PV2 . . . PVm are replaced in the inequations by the corresponding components o…
