Abstract

Detroit Edison’s (DTE’s) SmartCurrentsSM project involved deployment of distribution automation (DA) assets on 55 circuits, an advanced metering infrastructure (AMI) system to support 725,000 meters, a meter data management system (MDMS), a distribution management system (DMS), and various customer systems, including a new web portal, in-home displays, and programmable communicating thermostats. The DA component included implementation of automated switches and monitors for improved volt/VAR control at 11 substations. DTE also piloted a time-based rate program to assess demand response potential and customer acceptance. The project improved distribution system reliability, operational efficiency, and power quality. DTE also enabled customers to make more informed decisions about electricity usage to control costs.
