“…The review in [6] focuses on analyzing international standards and solutions for improving power quality, but it does not provide information about the different existing techniques to precisely locate the source of disturbance. In [7,8], the existing methodologies for the Responsibilities Assignment Problem are described and reviewed. In [9], the important novelty is that these existing methodologies are compared through a laboratory setup.…”

The complexity in the power system topology, together with the new paradigm in generation and demand, make achieving an adequate level of supply quality a complicated goal for distribution companies. The electrical system power quality is subject to different regulations. On one hand, EN-50160 establishes the characteristics of the voltage supplied by public electricity networks, therefore affecting distribution companies. On the other hand, the EN-61000 series of standards regulates the electromagnetic compatibility of devices connected to the network, therefore affecting the loads. Power companies and device manufacturers are both responsible and affected in the issue of quality of supply. Despite the regulations, there are certain aspects of the supply quality that are not solved. One of the most important is the location of the disturbance’s origin. This paper presents a review of the main techniques to locate the disturbance’s origin in the electric network through two approaches: identification of the disturbance’s cause and the location of the origin.

“…In this way, there are a lot of methods to determine the waveform distortion contribution or simply contribution throughout this text. Many of these are based on the Thevenin or Norton equivalent; some remarkable methods are summarized and analyzed in [5]. Nevertheless, this is still an open issue, given that there is no agreement about the reliability of the results, practical application, and plausible physical interpretation of the methods.…”

This paper explores the potential of some remarkable power theories derived from Fryze’s approach to assessing waveform distortion contributions. The analysis is limited to a simplified system composed of one load and one voltage source connected by a point of common coupling. Finally, some keys to assess are proposed for two types of systems: strong networks (traditional distribution systems) and weak networks (islanded microgrids).

“…At present, there is no any standard which illustrates the situation on how to make a choice of harmonic voltage index or harmonic current index, thus leading some researchers prone to misuse the indexes [18][19]. In literature [20], the shortcomings of the traditional methods for determination of harmonic responsibility are further analyzed, it points out that the traditional methods based on superposition projection principle can only determine harmonic responsibility under a certain frequency, and how to combine different frequencies of harmonic responsibility is also worth studying.…”

At present, the essence of traditional methods for determination of harmonic responsibility among different parts in power system is mainly based on the contribution of relevant physical quantity on the point of common coupling (PCC) of both utility side and customer side. However, theoretical basis of various methods is of much difference, leading to a large difference in the final calculation result of harmonic responsibility. Therefore, there is no reliable approach applied in actual cases. This project aims to fill the current gap in literature, proposing a new method to determine harmonic responsibility from the perspective of economic loss. Firstly, according to power theory of IEEE Std.1459-2010 and quality engineering theory, the index set of harmonic pollution evaluation on PCC is established, and the expressions of calculation of economic loss are obtained. Secondly, collecting relevant data on PCC, the parameters of Norton equivalent models of utility side and customer side are obtained by the reference impedance method, then contributions of corresponding physical quantity on PCC can be analyzed. Based on relevant expressions of economic loss, calculation results of economic loss are all obtained. At the same time, values of harmonic responsibility of utility side and customer side are calculated. Finally, new adjustment scheme of rewarding-penalizing electricity charge (RPEC) is discussed and compared with other traditional schemes. After comparison, Results of comparative analysis show that the new adjustment scheme can not only increase the penalty for harmonics but also reflect commodity characteristic of electricity energy. In this manner, calculation result of electricity charge is more reasonable. Hence, electricity environment on PCC can be improved.
