FEATURES OF LARGE-SCALE COMPRESSED AIR ENERGY STORAGES DEVELOPMENT

Transition to low-carbon electric power using high-capacity renewable energy sources is possible only if there are flexible-load units in the energy system structure. This problem can be solved both by traditional power plants using fossil fuels in steam and gas turbine cycles, and by advanced plants based on hydrogen or energy storage systems. As one of the options for covering the peak loads of the energy system, the application of compressed air energy storages (CAES) can be considered. In this article, the author analyzed thermal schemes of various CAES configurations; proposed equipment solutions of high-capacity CAES for the conditions of the unified energy systems of South and Center of the Russian Federation; calculated the operating modes of the CCPP in combination with the CAES; proposed approaches for creating an energy storage system for the unified energy system of the Russian Federation.
