Abstract: The use of the cloud to store and backup data is quite common everywhere and power companies are doing the same. There has been some hesitation in utilizing the cloud in the power system operations area where the data is more sensitive and is often needed in close to real time. Moreover, the measurement data is being scanned at faster rates today than ever before like in PMU measurements. We ran some experiments with control center real time PMU data to measure what kind of delays are experienced if this data is stored and exchanged through the cloud. Our experience suggests that widespread use of the cloud to move real time operational data is feasible even for applications wide-area protection and control.
