Household electricity demand profiles - A high-resolution load model to facilitate modelling of energy flexible buildings

The objective is to present a high-resolution model of household electricity use developed based upon a combination of measured and statistical data. It is a bottom-up model, which uses the 1-min cycle power use characteristics of a single appliance as the main building block. The effect of parameters, such as the number of occupants and their attitude towards energy use is included in the model. Moreover, the model accounts for phenomena related to unexpected weather conditions and local/national events, e.g. TV shows. The main aim of model is to generate high-resolution household load profiles for investigation of flexibility potential of domestic appliances and network modelling. The model is validated with two datasets of 1-h and 5-min data from 89 to 16 households, respectively. The comparison between measured and modelled values indicates that model well captures the characteristics of domestic electricity load profiles on a daily as well seasonal basis. For high-resolution data, the model represents well the differences in demand between households of dissimilar size as well as the diversity of demand between households of the same size. For the individual household, the high-end power consumption is under-represented since the timing of peaks is more diverse in the model. (C) 2016 Elsevier Ltd. All rights reserved.
