Leveraging advanced metering infrastructure for distribution grid asset management

Abstract

We show how it is possible to develop a system to improve management of distribution grid assets using AMI. In particular, we demonstrate how distribution transformers can be monitored and therefore, managed, even when there are no direct communication channels between the transformers and the asset management system. As an example, using smart meter interval load measurements, load and aging of oil-immersed distribution transformers is estimated with high-temporal resolution, being limited only by the smart meter measurement interval.
