چکیده انگلیسی
An integrated micro gas turbine, compressed air energy storage and solar dish collector system is proposed and analyzed. The required equations for modeling different components of the system are presented. Performance of the system is analyzed by changing effective parameters including maximum and minimum pressure of the cavern, inlet temperature of the gas turbine and outlet mass flow rate of the cavern. Performance of the system is investigated by energy and exergy analyses methods. The results show that in design condition, the plants charging and discharging times are six and 5 h, respectively. During the operating time, the system consumes 152 kW h and produces 228 kW h. It is also capable of producing four tons of hot water. The highest exergy destruction occurs in dish collector. Optimization results indicate that round trip efficiency increases with the difference between the minimum and maximum pressure of the air cavern. In the optimum operating point, round trip efficiency of the system increases by 4.2% compared to the situation before optimization.
