A methodology to refine the technical losses calculation from estimates of non-technical losses

This work proposes a methodology to improve the calculation of technical losses in power distribution networks using estimates of non-technical losses. The estimation procedure of non-technical losses is based on the history of energy consumption of consumers and on the results of field inspections. As motivation, we have the fact that the main methodologies to compute technical losses proposed in the literature do not consider the influence of non-technical losses, and hence are not very precise. The methodology here developed is very flexible, robust and can be applied even when the irregularities history maintained by the utility company is small. The clustering and sampling techniques used allow an estimation of technical losses closer to the real one.
