INRTU scientists are working on improvement of the effectiveness of the energy storage system

Natalia Shamarova, INRTU employee, is conducting a study on the topic “Analysis of the problem of frequency control using electric energy storage in isolated power supply systems with a high proportion of wind turbines”. This scientific research is conducted within the Priority 2030 federal program, toward one of the strategic areas of the university development - Digital industrial technologies .

Natalia Shamarova started her research as a postgraduate student three years ago. Then she went on a six-month internship at Magdeburg-Stendal University of Applied Sciences (Germany).

Natalia studied European experience in assessing the charge of lithium-ion energy storage (LES). These are high-capacity batteries that are used in Smart Grid power supply networks in conjunction with solar and wind power plants.

Upon returning to the Russian Federation, the author continued to work on the project. The key task of a young power engineer is to create a model of an isolated power supply system, taking into account the lithium-ion energy storage system to increase system’s reliability.

By this point Natalia managed to analyze the problems of random power fluctuations, the use of LES to compensate for them during storage degradation. In addition, a model for assessment of the rechargeable batteries degradation rate under various conditions has been studied. This made it possible to determine the most optimal battery operation parameters for extending the service life.

A university employee is preparing two scientific articles on this topic. The materials will be published jointly with colleagues from a German university in such journals as the Web of Science and Scopus.

 Konstantin Suslov, head of the Department of Power Supply and Electrical Engineering, commented on the project that the results of the research will be able to attract the attention of scientists and developers of power supply systems for isolated areas. Besides, they are of interest to manufacturers of electric vehicle charging stations.
