The use of Hybrid Power Generation Systems through renewable sources has been gaining prominence, since it is a way to reduce the dependence on fossil fuels, contributing to the reduction of pollutant gas emissions to the environment. Due to the higher operational complexity, the multiplicity of options and constant improvement of these units, how to optimize these systems is still a subject of present studies. Considering the attention that this topic has received from the academic community, the challenges for mapping and identifying the relevant literature, this article provides a macroscopic view of the scientific literature on the Optimization of Hybrid Renewable Energy Systems (HRES) for energy generation, through analysis bibliometric. The research was developed using the Web of Science database, obtaining a total of 439 articles between 2010 and 2020, where the results were interpreted through the VOSviewer software. The results showed that the number of related publications is gradually increasing, with India as the leading country. The University of Malaya is the institution with a higher number of registers, with 14 entries. Most publications fit into the “Energy Fuels” category, with the magazines “Renewable Sustainable Energy Reviews” and “Renewable Energy” as the most influential in terms of the number of publications, as well as the United States and China are the countries with most research collaboration. Besides, the most cited articles and the recurrence and distribution of keywords indicate the future directions of research. In short, this study contributes valuable information to researchers on the topic.
