| contents | Nonintrusive energy disaggregation by detecting similarities in consumption patterns Juan P. Chavat Jorge Graneri Sergio Nesmachnow Ingeniería Non energyefficiency pattern similarities intrusive load monitoring Breaking down the aggregated energy consumption into a detailed consumption per appliance is a crucial tool for energy efficiency in residential buildings. Non-intrusive load monitoring allows implementing this strategy using just a smart energy meter without installing extra hardware. The obtained information is critical to provide an accurate characterization of energy consumption in order to avoid an overload of the electric system, and also to elaborate special tariffs to reduce the electricity cost for users. This article presents an approach for energy consumption disaggregation in households, based on detecting similar consumption patterns from previously recorded labelled datasets. The experimental evaluation of the proposed method is performed over four different problem instances that model real household scenarios using data from an energy consumption repository. Experimental results are compared with two built-in algorithms provided by the nilmtk framework (combinatorial optimization and factorial hidden Markov model). The proposed algorithm was able to achieve accurate results regarding standard prediction metrics. The accuracy was not affected in a significant manner by the presence of ambiguity between the energy consumption of different appliances or by the difference of consumption between training and test appliances. 2021 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43067842003 https://www.redalyc.org/journal/430/43067842003/ https://www.redalyc.org/journal/430/43067842003/html/ https://www.redalyc.org/journal/430/43067842003/43067842003.epub https://www.redalyc.org/journal/430/43067842003/movil 10.17533/udea.redin.20200370 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.98 |
