摘要

The paper presents a novel hierarchical gas?gas system cooperating with a compressed-air energy storage in terms of thermodynamic and economic analysis. The gas?gas hierarchical cycle is considered in two variants: with and without compressors intercoolers. The mathematical model of the thermodynamic cycle and the air storage is based on the perfect and semi-perfect gases using the Clapeyron?s equation. This approach, despite some inaccuracy of temperature determination of working medium compared to the real gas model, allows to find the optimal value of pressure ratio by analytic differentiation. The analysis presents characteristics of: main thermodynamic parameters of the cycle as a function of turbine inlet temperature; air storage volume as a function of air mass flow rate; main economic parameters as a function of gas turbine power and reduction of unit electricity production cost as a function of electricity price, duration of off-peak hours, value of investment capital, interests rate, and the gas turbine power in terms of reduced values.
