Characteristics of the parameters of lithium iron phosphate energy storage in the context of their usefulness in the management of distribution grid

Purpose: The article presents the results of research on lithium iron phosphate energy storage. The subject of the study was to gain knowledge about the potential benefits of using this type of storage for storing energy from distributed sources. The goal was achieved, among other things, by estimating the efficiency, calculating the capacity and investment/operating costs of the tested technology.

Design/Methodology/Approach: During the research, the following work was carried out: Comparative analysis of technical parameters, literature research, desk research.

Findings: The research results showed possible positive effects of the use of lithium iron phosphate energy storage in micro-source systems due to the low internal resistance. The authors also emphasize the twice longer service life of the tested solution about acid batteries, which is particularly important in high investment costs.

Practical implications: The dynamic development of distributed generation determines the growing interest in energy storage technologies. These solutions are tested in terms of the possibility of using them to stabilize the operation of power grids and the absorption of surplus energy. The storage technology described in this article is one of the few most promising for large-scale use. Distribution system operators can use the test results.

Originality/Value: The survey attempts to fill a gap in the literature on the subject. The study provides practical answers about the characteristics of the described solution and the costs of its use. The results may encourage the use of this technology by companies from the energy sector as one of the solutions supporting the energy transition.
