Abstract
In the article, a pre-design assessment of single-, double-, and three-circuit low-temperature power plants (LPP) for cryogenic energy storage systems was carried out, taking into account their technical characteristics. A computational study of efficiency indicators was carried out using an improved general methodology for the integrated design of LPP to perform the calculation and analysis of the energy characteristics of the LPP taking into account their peculiarities. In addition, the most efficient LPP for a cryogenic energy storage system was selected in terms of the optimal parameters for low-temperature power plants.

Keywords: cryogenic energy storage system, low temperature power plant, air liquefaction, nitrogen liquefaction, Rankine cycle, Brayton cycle.
