Title: Estimating Customer Impact of Volt-Watt Using Only Smart Meter Voltage Data

Abstract

The autonomous inverter control mode known as volt-watt control can be useful as a backstop against high customer voltages outside of the ranges specified in ANSI C84.1 (i.e. above 1.05-1.06 per unit). Volt-watt control mitigates high voltages by directly reducing the active power output of a distributed energy resource based on local voltage measurements. Therefore volt-watt control also can impact the energy produced by the DER (e.g. PV system), especially for customers with persistently high voltages, and in such cases it is difficult to determine exactly how much the DER has been curtailed because it is not generally known exactly how much energy the PV system could have produced. These slides propose a relatively simple method of estimating the DER's energy curtailment using only data from the utility advanced metering infrastructure (AMI) data). The method proves surprisingly accurate when validated against detailed quasi-static time-series simulations and against limited field data.
