Non-intrusive load disaggregation model for residential consumers with Fourier series and optimization method applied to White tariff modality in Brazil

Abstract This paper proposes a novel approach to achieve better results for the Non-intrusive load disaggregation model for residential consumers. The proposed methodology considers two steps to face the problem. Firstly, periodical appliances are modelled by the Fourier series and extracted from the total power measured. Secondly, a Mixed Integer Linear Programming was proposed to disaggregate the remaining appliances. The paper presents results with a real case and indicates that the model can be useful for practical applications, such as the possibilty of the consumers of changing the modality of their tariff contract.
