Accurate power allotment
First Claim
1. A method of correlating power, comprising:
- supplying power to a portion of a location through a power distribution line, the portion of the location including a plurality of electrical loads that draw power through a circuit breaker;
monitoring utilization of a statistical sample of the plurality of electrical loads, the statistical sample being a statistically significant number of the plurality of electrical loads that is less than all of the plurality of electrical loads;
calculating an estimated individual power draw for the statistical sample of the plurality of electrical loads based on the utilization;
calculating an estimated total power draw for each of a plurality of different times from the estimated individual power draw of the statistical sample of the plurality of electrical loads to generate a plurality of estimated total power draw values for the plurality of different times;
monitoring actual power draw at the power distribution line by the portion of the location and generating a plurality of actual power draw values for the plurality of different times; and
determining a functional relationship between pairs of actual power draw values and estimated power draw values, each pair comprising an actual draw value and an estimated draw value for the same time.

Abstract
The subject matter of this specification can be embodied in, among other things, a method that includes supplying power to a portion of a data center through a power distribution line. Utilization of a statistically significant sample of the computers is monitored, and an estimated individual power draw for each of the computers based on the utilization is calculated. An estimated total power draw is calculated for different times from the estimated individual power draws to generate a collection of estimated total power draw values for the different times. Actual power draw is monitored at the power distribution line and a collection of actual power draw values is generated. A function is fitted to pairs of actual power draw values and estimated power draw values, each pair comprising an actual draw value and an estimated draw value for the same time, and the function is then stored.
