A Bottom-up Modelling Approach for Household Power Profiles Using Time-series Measurements

In this paper, a bottom-up modelling approach of households equipped with appliances, photovoltaic and battery energy storage system (BESS) is proposed. In particular, to simulate the daily household power profiles, a high-resolution dataset of appliances is created, including ground truth data as well as laboratory measurements. The household model applies both to single- and three-phase installations and incorporates a technique to limit the irrational BESS operation under frequent power fluctuations. Indicative simulation examples demonstrate the performance of the developed model in terms of power consumption and evaluates the effectiveness of some of the model parameters.
