End-use load-shape estimation: Methods and validation

OSTI ID:6301505

This report presents initial attempts to validate two approaches for developing end-use load shape information by disaggregating more widely available whole-building load data. Researches obtained whole-house load data and associated survey responses for a sample of households in the service area of Pacific Gas Electric Co., who cofunded the study. End-use metered data were also available for a varying number of appliances for the same households, but were reserved for the validation exercise and not used in the analysis step. Two separate research teams applied alternative types of analysis techniques to estimate load shapes for individual end uses from the data. The two techniques involved different approaches for compressing the large number of hourly observations, and for incorporating engineering information on the operation of certain appliances. Researchers then compared the estimated end-use load shapes to end-use metered data, and assessed the relative performance of the two techniques. Both approaches produced estimated end-use load shapes that compared quite reasonably to the metered loads for some end used and time periods. However in a number of cases the estimated loads were not so accurate. Neither method clearly dominated the other in terms of accuracy, nor did there emerge a pattern with regard to the types of days or end uses for which one or the other method performed better.
