Abstract

The increasing number of residential distributed energy resources (DER) is driving the need for distribution companies to routinely assess potential voltage violations due to excessive power injections. However, this task can be quite challenging in low voltage (LV) feeders due to the limited availability of modeling data. To this end, this work proposes a practical approach to assess the effects of DER on voltages by exploiting historical time-series measurements from smart meters and head of the feeder. First, the impedances of three-phase feeders are determined assuming knowledge of feeder topology and service cable parameters. Then, the resulting smart meter-driven model is used to compu..
