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.

Harmonic emissions from converter-interfaced distributed generation connection can potentially lead to voltage distortion levels that are above applicable standards. The risk increases as greater connection volumes are facilitated by Active Network Management schemes. By incorporating harmonic limits into assessment of the hosting capacity of active networks, this paper demonstrates that by incorporating harmonic levels at the planning stage can prevent inadvertent restrictions on the integration of renewables. Other aspects considered include: the impact of active network controls on harmonic propagation and hosting capacity and the role of active harmonic mitigation methods.

“…This procedure may be Newton-Raphson-based technique [47][48][49][50] or a technique based on the injection current response of the network [49,50]. In each of these methods, the signal level at harmonic sources must be known, estimated or calculated.…”

SUMMARYThe increased use of power electronic controlled equipment, such as variable speed drives, automated production lines, personal computers and non-linear electronic devices in power systems has given rise to a type of voltage and current waveform distortion called as 'harmonics'. Harmonic can be defined as the undesirable components of a distorted periodic waveform whose frequencies are the integer multiples (non-integer multiples in case of inter-harmonics, and the frequency less than fundamental frequency in case of sub-harmonics) of the fundamental frequency. Presence of these harmonics results in increased losses, equipment heating and loss-of-life, and interference with protection, control and communication circuits as well as customer loads. The research has been underway since very beginning for control of power system harmonics and to supply consumers with reliable and 'clean' fundamental-frequency sinusoidal electric power that does not represent a damaging threat to their equipment. This paper, therefore, reviews the progress made in power system harmonics research and development since its inception. Attempts are also made to highlight the current and future issues involved in the development of quality and reliable electric power technology for future applications. A list of 145 research publications on the subject is also appended for a quick reference.
