Abstract: Disclosed techniques for power management include datacenter power management through phase balancing. Power for a datacenter is obtained across a plurality of AC power phases. A power consumption value by loads is determined within the datacenter for each of a plurality of power phases. A power consumption imbalance is calculated between a first phase and a second phase from the plurality of power phases within the datacenter. Phase power balancing is performed by transferring power from the first phase to the second phase from the plurality of power phases within the datacenter. The transferring power is accomplished using current injection. The performing phase power balancing by transferring power from the first phase to the second phase comprises a supply side transfer of power. Performing phase power balancing by transferring power from the first phase to the second phase is accomplished without transferring load power consumption between power phases.
