Application of AMI data to anomaly detection and dynamic power flow analysis

Advanced Metering Infrastructure (AMI) has been deployed at over 70% of rural electric cooperatives, and this new data source offers opportunities for valuable applications beyond billing. The National Rural Electric Cooperative Association (NRECA) has developed open source computer software to perform anomaly detection and dynamic power flow analysis with AMI data for the cooperatives (consumer-owned, not-for-profit utilities). We describe this software, discuss challenges to collecting and working with AMI data, and discuss further potential applications such as theft detection and technical loss estimation.
