Detailed Primary and Secondary Distribution System Model Enhancement Using AMI Data

Reliable and accurate distribution system modeling, including the secondary network, is essential in examining performance with high penetration of distributed energy resources (DERs). This paper presents a highly automated, novel method to enhance accuracy utility feeder models capture their by matching simulation results corresponding field measurements. The demonstrated using an actual from electrical DERs. proposed uses advanced metering infrastructure (AMI) voltage derived active power measurements at customer level, data acquisition systems (DAS) feeder-head, conjunction AC optimal flow (ACOPF) estimate reactive consumption over time horizon, while accounting for unmetered loads. ACOPF measured magnitudes, measurements, head obtain complete Additionally, estimates both magnitude angle each phase unbalanced substation. developed verified two stages: comparing time-series obtained enhancement algorithm OpenDSS available. approach seamlessly manages available optimization procedure through final model verification automatically.
