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.

“…It is reported that 10% smaller harmonic current magnitudes can be seen when phase angle information is included compared to the simple summing of magnitudes without phase angle values [10]. The attenuation effect is dependent only on the phase angle, but the effect's severity is dependent on the magnitude of the harmonic voltage [11].…”

The high utilization level of renewable generation including residential photovoltaic (PV) systems together with the uncontrolled charging of electric vehicles (EVs) can have a significant impact on load characteristics in distribution networks. Harmonic content of PV generation, EV charging loads, and their influence on power quality indicators in residential distribution networks are discussed in this paper. For investigating likely power quality scenarios, PV generation and EV charging measurement results including current harmonic amplitude and phase angle values are used and compared with present load characteristics. Different modelling scenarios are analysed and a simplified model of harmonics in PVs and EVs is offered. The results of the study show moderate additional harmonic distortion in residential load current and voltage distortion at the substation's busbar when PV generation and EV loading are added. The scenarios presented in this paper can be further used for modelling the actual harmonic loads of the PVs and EVs in distribution networks.

“…It is difficult to obtain detailed equivalent circuit parameters for each charger. Previous studies [21] have proposed a method using the measured AC current waveform of a single-phase uncontrolled rectifier under given voltage conditions to estimate the parameters of the harmonic analysis circuit. However, for the commonly used three-phase uncontrolled rectification charger, the charging current has two modes: the continuous conduction mode (CCM) and discontinuous conduction mode (DCM), which is different from that of the single-phase rectification circuit.…”

Abstract:The influence of electric vehicle charging stations on power grid harmonics is becoming increasingly significant as their presence continues to grow. This paper studies the operational principles of the charging current in the continuous and discontinuous modes for a three-phase uncontrolled rectification charger with a passive power factor correction link, which is affected by the charging power. A parameter estimation method is proposed for the equivalent circuit of the charger by using the measured characteristic AC (Alternating Current) voltage and current data combined with the charging circuit constraints in the conduction process, and this method is verified using an experimental platform. The sensitivity of the current harmonics to the changes in the parameters is analyzed. An analytical harmonic model of the charging station is created by separating the chargers into groups by type. Then, the harmonic current amplification caused by the shunt active power filter is researched, and the analytical formula for the overload factor is derived to further correct the capacity of the shunt active power filter. Finally, this method is validated through a field test of a charging station.
