Exergy analysis and exergoeconomic optimization of a constant-pressure adiabatic compressed air energy storage system
چکیده انگلیسی
A steady state model is then developed to perform an energy and exergy analyses of the IA-CAES system and evaluate the exergy losses distribution in this system. The efficiency of the storage system is 55.1% and the energy density is 11.9 kWh/m3. An optimization is also carried out by using exergoeconomic principles in order to minimize an objective function including investment cost of equipments and operating cost. The exergoeconomic analysis is performed by the specific exergy costing (SPECO) method and the optimizer used is OmOptim which is a genetic algorithms based optimizer. As results, the efficiency is improved by 2.7% and the consumed electricity cost is reduced by 2.8% whereas the capital investment is reduced by 5.6%. A sensitivity analysis is finally carried out to estimate the effects of some key parameters on the objective function and the system's efficiency, such as the storage system capacity, the ambient temperature and the fuel cost.
