Naturalne puste przestrzenie w górotworze (kawerny) lub podziemne wyrobiska górnicze mogą być wykorzystywane jako magazyny sprężonego powietrza, za pomocą którego można magazynować energię elektryczną w przypadku jej nadwyżek w dolinie potrzeb elektrycznych systemu elektroenergetycznego (istotnym problemem może być nieszczelność tych przestrzeni). Stosowanym od dawna sposobem magazynowania elektryczności...
In this study, a new compressed air energy storage (CAES) refrigeration system is proposed for electrical power load shifting application. It is a combination of a gas refrigeration cycle and a vapor compression refrigeration cycle. Thermodynamic calculations are conducted to investigate the performance of this system. Economic analysis is performed to study the operating cost of the system, and comparison...
