Big Data Analytics for Distribution System Monitoring in Smart Grid

Advanced Metering Infrastructure (AMI) is an integral part of Smart Grid. Utilities made huge investments in AMI to fully utilize the benefits of smart grid. Efforts must be made to utilize this infrastructure beyond billing purpose. Smart meters can act as a good sensor for distribution system monitoring. But system monitoring based on AMI requires real time computing of smart meter data. Considering the size of smart meters deployed, real time big data analytical tools and techniques are required for system monitoring based on AMI data. Stream Computing is a real time data analytical technique used in big data. In our paper system monitoring applications for outage detection and peak load tracking from AMI data is implemented using stream computing technique. This work revealed that stream computing is a promising big data analytics that can be used in real time applications of Smart Grid.
