Samara University Repository
Welcome to the Samara University repository!
This is an open electronic archive created to preserve and disseminate the scientific results of our university. The works of researchers, faculty members, and students are available to everyone for academic and research purposes.
The repository contains dissertations, research articles, educational and methodological materials, monographs, and regulatory documents. The collections cover a wide range of fields: from aerospace technologies, engine engineering, and computer science to history, linguistics, mathematics, and ecology. The archive brings together the scientific heritage of the university, including materials prepared during the period of Samara State Aerospace University and Samara State University.
Looking for publications by author, title, date, or subject? Full-text search will provide relevant results. Want to explore the academic life more closely? Browse materials by the universityâs organizational units.
Descriptions of all publications and articles available in the repository can be found in the libraryâs electronic catalog. Staff and students can log in via the menu "Login -> My Resource Archive" using their personal account credentials (SSAU_id).
Use the archive for study, research, and professional development!

| Abstract: | Cryogenic energy storage systems have significant potential in the field of increasing the stability of power systems by reducing the unevenness of load schedules and electricity generation. They have a higher energy capacity compared to other types of energy storage, but have a relatively low storage efficiency. Due to the wide variety of cryogenic energy systems designs, the use of any one efficiency indicator does not provide an objective picture, so this paper considers the assessment of the efficiency of energy systems in terms of energy, exergy and economic efficiency, and proposes a comprehensive indicator that takes into account all of the above factors. Analysis of published installations shows that the most efficient energy accumulators have a conversion efficiency of about 70% due to the use of compression heat in compressors and the cold of the cryogenic product. |
