“…Finally, a forecast of THDV in the previously studied networks was estimated, for the next two decades (Emanuel et al, 1995). Figure 2 shows that research conducted by Emanuel et al (1994), led to the work by Mansoor et al (1995a), where the harmonic interaction and diversity effect in harmonics produced by a large number of single-phase electronic loads were investigated. An analytic model was developed for a single-phase full-wave rectifi-er, typically utilized in residential loads.…”

Harmonic distortion in residential distribution networks is increasing due to the penetration of multiple nonlinear loads, including modern technologies such as plug-in electric vehicles and energy efficient lighting (e.g., compact fluorescent and LED lamps). The distributed nature of these loads introduces complexity in the analysis of harmonic propagation. Therefore, more sophisticated tools are needed to investigate this issue, on the basis of formerly established methodologies. This paper presents a literature review on the assessment of the harmonic distortion in residential distribution networks. To that end, bibliographic data of the most representative publications related to the topic were obtained. From these data, a novel citation analysis method was developed to construct a chronologically organized direct citation network. Based on the temporal evolution of the citation network, the aforementioned issue is presented, identifying lines of research and proposed methodologies. From the analysis of the literature review, the stages for modeling and simulating harmonic propagation are identified and described. The principal aspects to be addressed for obtaining an accurate harmonic analysis are also identified and detailed, namely, harmonic interaction, diversity, unbalance, and uncertainty. Finally, main conclusions are highlighted.Keywords: Electric power system, harmonic distortion, power quality, systematic review. RESUMENLa distorsión armónica en redes de distribución está aumentando debido a la penetración de múltiples cargas no lineales, incluyendo tecnologías modernas como los vehículos eléctricos y las lámparas de alta eficiencia energética (por ejemplo, lámparas compactas fluorescentes y LEDs). La naturaleza distribuida de estas cargas introduce complejidad en el análisis de la propagación de armónicos. Por lo tanto, se necesitan herramientas más sofisticadas para investigar esta temática, sobre la base de metodologías establecidas. Este artículo presenta una revisión literaria sobre la evaluación de la distorsión armónica en las redes de distribución residencial. Para ello, se obtuvieron datos bibliográficos de las publicaciones más representativas relacionadas con el tema. A partir de estos datos, se desarrolló un nuevo método de análisis de citas para construir una red de citas directas, organizada cronológicamente. Con base en la evolución temporal de la red, se observan las líneas de investigación y las metodologías propuestas. Además, se identifican las etapas para el modelado y simulación de la propagación de armónicos y se detallan los aspectos para obtener un análisis armónico preciso, a saber, interacción armónica, diversidad, desequilibrio e incertidumbres. Finalmente, se presentan las conclusiones.Palabras clave: Calidad de potencia, distorsión armónica, revisión sistemática, sistema eléctrico de potencia.

“…Tais fontes harmônicas (cargas não lineares) estão distribuídas por toda a rede. Embora estas cargas individualmente produzam quantidades insignificantes de correntes harmônicas, o efeito conjugado de um grande número de tais cargas pode ser significativo [1]- [3], podendo criar uma série de perturbações para as concessionárias e para os usuários finais [4].…”

Resumo -Este trabalho apresenta uma análise de cargas lineares e não lineares em condições senoidais e não senoidais para verificar seu comportamento como "fonte de tensão" ou "fonte de corrente" distorciva. Discute ainda problemas relacionados com a medição e tarifação da energia no ponto de acoplamento comum. Para tanto é utilizada a Teoria de Potência Conservativa para encontrar circuitos equivalentes e a partir destes circuitos analisar as principais características das cargas lineares e/ou não lineares bem com o tipo de não linearidades presentes. As análises são comprovadas com base em simulações e dados experimentais de cargas típicas de uso residencial e industrial. Além disso, será discutida a adequação do fator de potência como indicador apropriado para caracterizar e penalizar o consumidor (carga) quando também é produtor (gerador), situação comumente encontrada em microrredes. Palavras-Chave LINEAR AND NONLINEAR LOAD CHARACTERIZATION UNDER NON SINUSOIDAL CONDITIONSAbstract -This paper presents an analysis of linear and non-linear loads under sinusoidal and non-sinusoidal operation to verify their behavior as harmonic "voltage source" or "current source". Harmonic related problems involving the revenue metering at point of common coupling are also discussed. Conservative Power Theory is used to build equivalent circuits, used to analyze the main features of those loads, as well as the type of nonlinearities present. Simulation and laboratory tests are realized in order to support the theoretical conclusions. Moreover, it is shown that the power factor may not be a confident indicator for load characterization in the case a consumer is also an energy producer (generator), as commonly occurs in smart microgrids.

“…Although being power electronic based and being energy efficient are not synonymous, most of the energy‐efficient loads are based on power electronics. In general, these appliances consume considerably less power than their older counterparts . Newly introduced appliances are adjustable speed drive (ASD)–based fridges, heat pump furnaces, fans, laundry dryers, and washers ; computers, monitors, laptops, and TV sets using switch‐mode power supplies ; microwave ovens, home entertainment systems, and CFLs; and many other electronic loads.…”

Most of the modern home appliances use power electronic circuits as a power supply to interface with the distribution grid. They have become a major source of harmonic distortions in power distribution systems. This article presents a study of the harmonic current characteristics of such appliance through a measurement-based comparative approach. Magnitude-related indices are introduced to compare the harmonic effects of the various appliances and to quantify their relative severity. Phase angle-related indices are introduced to study the diversity of the current harmonics phase angle among the devices and to understand its effect on harmonic cancellation. The proposed approach can be used to establish a database of harmonic characteristics for home appliances and other small, distributed harmonic-producing loads.
