Analysis of Risk Factors and Harmonics Incidence in a Distribution Grid based on the Epidemiological Methodology

A methodology based on epidemiological analysis for  assessing risk factors and harmonic distortion incidence rate in a distribution network is proposed in this paper. The methodology  analyze possible current harmonics emission of typical residential loads by means of modeling. These loads are modeled and multiple loads connection scenarios are simulated using Monte Carlo Algorithms. From the simulation results, potential risk factors for critical harmonics indicators are identified, leading to a classification of the scenarios into groups of exposed or unexposed to risk factors. Finally, the incidence rate of harmonics is calculated for each load connection scenario and the risk of critical harmonics scenarios due to the exposure to risk factors is estimated.
