“…The methodology proposed by the governmental holding ELETROBRAS was the main reference in the country [5]. In the last ten years, various methods have proposed a special treatment towards load, employing data from load curves registered within a 15 minutes integrated period [6], or using typical loads in function of days (workdays, Sunday, Saturday), months and consumer classes [7]. Usually, in each segment, energy loss is estimated by gathering peak-demand loss, which is calculated through maximum demand and using "loss factor", that is, the relation between average and peak-demand loss [4], [6] .…”

The following paper proposes a simplified method for calculating energy losses on diverse distribution segments, highlighting important aspects not considered by other methodologies. Simulation studies have been performed to demonstrate the importance of these aspects and the adequacy of the proposed method. The method is applied to evaluate energy losses in low voltage system using a probabilistic model.

“…To be succeeded on the energy losses reduction objective, there is a need for identifying and accessing the losses throughout the distribution system. Energy losses can be classified as to their origin and location (Méffe, A., 2001). Regarding their origin, a loss can be categorized into technical and non-technical one.…”

Along the last years, electrical energy distribution companies have already done many investments in order to identify and calculate energy losses along a distribution network. Although these big efforts, most approaches for clearly identifying and solving the related problems still remain rather inefficient. The accurate identification and the precise calculation of electricity losses enables the clear specification of the critical points and segments in the networks and, consequently, the effective prioritization of actions and interventions in order to reduce those electricity losses and problems. Moreover, the work already performed on this issue, the existing approaches focus mainly on empirical and probabilistic data. Hence, there is still a clear gap between real information and the considered one, which tends to be poor and imprecise. Due to this reality and the lack of appropriate software applications, in this paper we propose a web platform for the management of the whole network of electrical energy distribution, from medium voltage (MV) down to low voltage (LV), including billing on the transformation centers (TCs), electricity losses calculation and proposals for solving actions, by means of a fuzzy decision-making model.

“…Tendo em vista a relevância do assunto, muito tem sido pesquisado e publicado a respeito do cálculo das perdas técnicas. Em [8], antes mesmo do 1 o CRTP, tem-se uma das contribuições mais relevantes no contexto brasileiro, em que o autor propõe o cálculo das perdas técnicas dividindo-se a rede da distribuidora em segmentos, a saber: medidor de energia, ramal de ligação, rede secundária, transformador de distribuição, rede primária, subestação de distribuição, sistema de alta tensão e, ainda, um segmento que incorpora as parcelas de perdas técnicas referentes a equipamentos, como por exemplo, capacitores e reguladores de tensão, perdas em conexões, corrente de fuga em isoladores, etc.…”
