Abstract
Power quality is a research field related to the proper operation of devices and technological equipment in industry, service, and domestic activities. The level of power quality is determined by variations in voltage, frequency, and waveforms with respect to reference values. These variations correspond to different types of disturbances, including power fluctuations, interruptions, and transients. Several studies have been focused on analysing power quality issues. However, there is a lack of studies on the analysis of both the trending topics and the scientific collaboration network underlying the field of power quality. To address these aspects, an advanced model is used to retrieve data from publications related to power quality and analyse this information using a graph visualisation software and statistical tools. The results suggest that research interests are mainly focused on the analysis of power quality problems and mitigation techniques. Furthermore, they are observed important collaboration networks between researchers within and across countries.
Highlights
Power Quality is essential to guarantee the appropriate operation of electrical and electronic devices in domestic [1], commercial [2], and industrial environments [3]
We present the validation of the proposed methodology by analysing both the most investigated topics in power quality and the scientific collaboration network based on the co-authoring of articles that contain keywords related to power quality
We quickly processed the scientific production in power quality and its related areas according to keywords, by considering the information on several publications from 1970 to 2016
Summary
Power Quality is essential to guarantee the appropriate operation of electrical and electronic devices in domestic [1], commercial [2], and industrial environments [3]. A low power quality increases energy costs and might affect the increasingly sensitive modern equipment [4]. The current upward trend in large-scale integration of distributed energy resources in distribution networks has fueled interest in knowing their power quality issues [6,7]. The increasing and varying energy demands cause many loads to generate disturbances that lead to deviations from these ideal conditions, which is why some studies strongly support the need for public policies for energy efficiency and power quality improvements [8]
