“…Thus, if this is not the case, the accuracy of this algorithm can be highly affected. In general, References 4,16‐19,21 reported good results of harmonic estimation. However, they did not take into account studies on transmission systems with different sizes or if a higher number of nonlinear loads exists.…”

“…In this way, References 16,17 use ES algorithm for HSE, including, in addition to the measurements of harmonic voltage and current phasors, voltage measurements at the fundamental frequency. On the other hand, the methodology of harmonic estimation of Reference 18 uses solely information related to harmonic frequencies. In Reference 19, the SOA is utilized for HSE.…”

Summary In line with the accomplishment of PQ standards, the search for methodologies to estimate harmonic distortions in large electrical networks, using a small number of meters, emerges as a challenging subject. In this way, this paper proposes a new methodology for HSE in underdetermined power systems monitored with a small number of meters. The HSE approach is modeled as an optimization problem, for which, the solution is achieved using a new strategy, called HA, obtained from the union of the ES algorithm based on CMA with the SADE algorithm. To highlight the approach application, simulations studies are carried out using two transmission systems, and the results enhance the estimation accuracy offered by the HA in comparison to two other HSE methods.

“…One of the problems of power quality observed in recent years is the level of harmonic distortion in electrical systems. This problem is largely due to an ever increasing amount of power converters and nonlinear loads that distort current waveforms and, therefore voltage waveforms in the electrical system [23]. Nonlinear loads generate harmonic currents that are injected into the electrical system and consequently pollute and distort the waveforms of other connected loads [24].…”

Luiz Carlos Pereira da Silva, for all the guidance and support over the last years.Additionally, I would like to thank my colleagues from Brazil and Denmark, who were always available to make technical discussions, advise me and collaborate during my Ph.D. In particular, I would like to thank few people: Pedro Pablo Vergara Barrios, for all his support and patience at the beginning of my journey, as well as Seyyedeh Newsha Ghoreishi, who welcomed me and my family into her sweet home -I have no words for show how grateful I am for you. Also, still in Denmark, a special thanks to Athila Quaresma dos Santos, a Brazilian friend who I met so far from our country. Finally, I would like to thank Rodolfo Quadros for all the partnerships during the writing process of all the papers. I would like to acknowledge the three universities for all their support in developing this Ph.D. project: Federal University of Mato Grosso (UFMT), where I work; University of Campinas (UNICAMP) and University of Southern Denmark (SDU), these last ones I am so glad for allow me to participate in a dual degree program. Thanks to Karina Schwartz, Luna Larsen, Louise Møller and to all SDU staff team. Thanks also to all scientists and engineers who have contributed to the development of the state-of-the-art as we know it today.Last, but none less important, I thank my family in Brazil, my dad José Carlos, my mom Sandra Perillo, my brothers Rafael and Renan and his respective families, my wife Vivian Petenucci and her family, and my sweet and lovely daughter, Mariana Bressan. I hope you all feel proud of me. Thank you for all."Insanity is doing the same thing over and over again and expecting different results."Unknown author.
