Load component database of household appliances and small office equipment

This paper discusses the development of a load component database for household appliances and office equipment. To develop more accurate load models at both the transmission and distribution levels, a better understanding of the behaviors of home appliances and office equipment associated with the variations of the power system voltage becomes more and more critical. The Bonneville Power Administration (BPA) has performed a series of voltage tests against home appliances and office equipment since 2005. Since 2006, researchers at Pacific Northwest National Laboratory have collaborated with BPA personnel and developed a load component database based on the appliance testing results to facilitate load modeling work for the Western Electricity Coordinating Council (WECC). In this paper, the testing procedure and results are first presented. Then, the load model parameters are derived and grouped. Recommendations are given for aggregating the individual appliance models to the feeder level, the models of which are used for distribution and transmission level studies.
