Conservation voltage reduction system modeling, measurement, and verification

A utility has recently installed a conservation voltage reduction (CVR) system on multiple distribution substations in order to test, measure and verify the performance of the system, as well as provide peak demand and energy reduction. The testing of the system is to determine the effects of particular CVR implementations on customers´ loads, while maintaining voltages within the ANSI C84.1 standard range. The measurement and verification of the performance of the system on one of the distribution substations is the subject of this panel session. We will discuss the measurement and verification (M&V) protocols used, their application, and the results from a test period covering one calendar year. Finally, we will discuss lessons learned from the M&V process that are particular to the system under study.
