Economic assessment of the prospects for the use of CAES to maintain the modes of the power system

The article is devoted to the study of modes maintaining issues of the energy system in the presence of large generation facilities based on renewable energy sources. The object of the study was a source of generation of electric energy on organic fuel located in the unified power system of the South of Russia, which is operating in combination with a compressed air energy storage (CAES) for operation in peak generation mode. The calculation of the operating characteristics of the combined heat and power plant (CHP) was carried out using the information and analytical platform "EMAS.OPT". The platform is based on the creation of digital models of industrial enterprises for subsequent optimization of equipment operating modes according to the criterion of profit maximization. The results of the calculation of various operation modes of the power plant are presented and the use of this combination is evaluated based on technical and economic indicators.
