“…In this regard, the scientific community has been faced with a number of tasks, namely, the development of methods and devices for harmonics compensation, and the development of methods for assessing the impact of each nonlinear consumer on the quality of electricity at the PCC [12,13]. The first issue has been considered in detail in [14][15][16][17][18][19][20], and various configurations of active, passive, and hybrid harmonics filters have been proposed.…”

“…HF are measured for the resonant frequency h. The previously installed filter can be used or an additional filter should be connected as part of the measuring equipment. All required data can be obtained by a standard power quality analyzer; • Calculations of the PSS contribution are made according to (12). If the utility is the dominant source (contribution is more than 50%), then no additional measures to eliminate harmonics at the consumer's side should be provided since the measures from the utility side are paramount.…”

Method for Evaluation of the Utility’s and Consumers’ Contribution to the Current and Voltage Distortions at the PCC

et al. 2021

In this article, a method that allows sharing responsibilities for the generation of harmonic currents between the utility and consumers powered by one point of common coupling (PCC) is addressed. For these purposes, mathematical modeling of the power supply system (PSS) with two consumers is carried out in order to introduce new indices using the simplest PSS structure as an example. Two indices are introduced that quantify the consumers’ contribution to the distortion of current and voltage at the PCC and that evaluate harmonic emission from the utility side. Experimental tests are carried out where both linear and nonlinear loads are considered, capacitive loads are taken into account, and harmonic distortions from the utility side are modeled to show the applicability of the indices in a wide range of load types. The experiments confirmed the theoretical results and illustrated that the quantitative assessment of the contributions is unambiguous. It suggests that the proposed criterion could be a reasonable basis for further tax policy on harmonic pollution for each consumer at the PCC and for the utility.

“…-The metering engineers had little or no interest in the subject since it was believed that the level of harmonics in the power system was not high enough to cause problems with revenue meters. [193] -The modern power metering devices contain formulas for calculating power, which do not take into account the influence of higher harmonics.…”

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.

The issues related to modeling a variable frequency drive are discussed in the article. The authors were faced with the task of determining the influence of the drive load on the parameters of its equivalent circuit. An unambiguous dependence of the drive load on the value of the current’s harmonic components is revealed. Namely, the smaller the load, the greater the value of the current’s higher harmonics. It has been established that disregarding drive loading can lead to a 19% error in modeling the frequency converter current consumption. It is shown that the results of the study can be extended to a wide range of drives in terms of power, since all calculations were performed in relative units.
