Abstract

Methods, systems, and apparatus for managing power in a data center. In one aspect, a method includes monitoring respective phase power level in each phase of an alternating current multi-phase supply that provides power to a plurality of data center alternating current devices in a data center, comparing the respective phase power levels to phase distribution criteria that describe a target phase power level for each respective phase and determine, based on the comparison, a deviation of one or more of monitored phase power levels from the respective one or more target phase power levels and in response generate, for each of two or more data center alternating current devices, respective control signals to adjust the one or more adjustable phase power supplies in the data center alternating current device according to a determined adjustment for the data center alternating current device.
