Energy and power savings assessment in buildings via conservation voltage reduction

Abstract

This paper evaluates the potential energy and power savings from application of Conservation Voltage Reduction to buildings with load diversity. Slow and fast voltage change experiments were performed to develop regression models with which the conservation voltage reduction energy and power factors were evaluated on a subject building. Least mean squares algorithm was used for the estimation of these parameters. The experimental results of 6 months of recordings captures not only the enforced voltage changes but also the existing voltage deviations on a feeder, weather conditions and load patterns.
