Abstract :
In this paper, the economy of supercritical compressed air energy system is evaluated by using thermal economic method. Electricity price of input system to evaluate selects by the beijing municipal market price for peak and valley, and uses Engineering Equation Solver software to simulate. The results show that the electricity price of output is 0.5153 RMB/kW·h, while electricity price of input system is 0.3148 RMB/kW·h by 35 kV valley market price, there is obvious economic advantages compared to the peak market price. This system has no CO2 and other greenhouse gas emission comparing with the compressed air energy storage system, it can also reach the purpose of regulating network load and improve renewable energy power system efficiency, so it has significant environmental and economic advantages.
