D2: Distribution Engineering or Operations Optimize Network based on Data Collected by the AMI System
Abstract:

Optimizing the network involves issues with feeder loading, voltage profile, efficiency, reliability and quality. The utility uses feedback from the AMI system to both improve customer power quality and reduce distribution costs to the utility. Possible AMI outputs include average voltage at customer site, voltage variations seen by the customer, power consumption by time interval, harmonics (voltage and/or current), power production by customer-supplied distributed generation, and customer power factor. Possible uses for this data include warning letter issued to customers (if they are adversely impacting the network), feeder capacitor bank switching, transformer voltage tap switching, input to load forecasting models (both short- and long-term), feeder harmonic filter controllers, and feeder switching decisions. This scenario also includes addressing power quality contract compliance as a sub-scenario. This scenario includes options for both real-time monitoring & control, and off-line analysis of historical data to determine system optimization options as sub-scenarios. This scenario also includes using the AMI communications network to provide connectivity to distribution system devices (e.g. IEDs / RTUs, sensors, fault indicators, etc.) in addition to, or instead of the measurement information from the customer meter as a sub-scenario
