Patent ID: 8401833

Claim:
A system for making real-time predictions about power usage efficiency (PUE) of an electrical system, the system comprising: a data acquisition component communicatively connected to one or more sensors configured to acquire real-time data output from the electrical system of a data center, wherein the real-time data output comprises real-time data for one or more transformers in the data center and real-time data for one or more power supplies providing power to information technology (IT) equipment in the data center; and an analytics server communicatively connected to the data acquisition component, the analytics server comprising a virtual system modeling engine configured to generate predicted data output for the electrical system using a virtual system model of the electrical system, an analytics engine configured to monitor the real-time data output and the predicted data output of the electrical system, and validate the virtual system model using the real-time data output, and a PUE simulation engine configured to receive one or more modifications for the data center, modify a copy of the validated virtual system model based on the received modifications, and use the modified copy of the validated virtual system model, to forecast the PUE for the data center with the one or more modifications, wherein the PUE comprises a ratio of total power dedicated solely to the data center to a measure of load associated with the IT equipment in the data center.
