RESEARCH ON THE ENERGY GRIDS TRANSFORMATION WITH THE SMART TECHNOLOGIES USED IN ENTERPRISES

Rapid changes in energy technologies, the emergence of new opportunities and energy resources, and evolution in fundamental views on energy systems' functioning can be an impetus for the energy sector's transformation at both the macro and individual enterprise levels. Smart technologies in energy are a source of diffusion of innovations for various spheres of economic activity. However, when transforming energy networks, it is essential to take into account external and internal factors related to adaptation to new technologies. In addition, there may be technological, economic, social, or political constraints and risks that make it impossible to implement energy network transformation projects. Accordingly, this study aimed to study the transformation of energy networks using smart technologies in enterprises by reviewing and clustering publications in publications indexed by the Scopus database. As a result of the bibliometric review of 608 publications on energy network transformation published in leading journals in 2017-2020, the main trends in the energy sector were identified. The vast majority of energy network transformation projects were devoted to the renovation of existing electricity networks, developing micro-networks, and introducing energy storage and consumption systems. Most of the projects were described in documents in 6 thematic areas: energy (26.7%), engineering (23.0%), environmental sciences (11.3%), computer science (11.2), mathematics (7.1%), social sciences (4.1%). Analysis of the geographical distribution of authors of scientific works studying the transformation of energy networks showed the most significant number of publications published by scientists from the United States, China, and Germany. When transforming energy networks, companies use a wide range of solutions. The latter cover virtualized / cloud architectures, efficient polar coding for fronting, DC vector control technologies, passive cooling, and other solutions to increase system performance and stability, support energy storage systems, and actively engage consumers.
