Modelo Matemático para a Detecção e Localização de Perdas Não Técnicas nos Sistemas Distribuição de Energia Elétrica com Medidores Inteligentes

Abstract

Non-technical losses are related to energy theft, default, and pricing errors in electrical energy distribution systems (SDEE). With technological advancement dedicated to SDEE using smart meters, it has become possible to detect and locate non-technical losses. In this context, this paper aims to develop a second-order conic programming mathematical model to solve the problem of detecting and locating non-technical losses in medium and low voltage SDEE. The proposed model is based on measurements of voltage magnitude, active and reactive power obtained through smart meters connected to the SDEE. The proposed model was written in the algebraic modeling language AMPL and solved using the commercial solver CPLEX. The obtained results show that is possible to analyze the relationships between measured quantities and identify non-standard cases. Different studies were carried out on 34 system to evaluate the performance of the proposed mathematical model. The results show the efficiency, scalability, and sensitivity of the proposed methodology for detecting and locating non-technical losses.
