基于200MW等级压缩空气储能系统中温与高温储热路线技术经济对比
Technical and economic comparison of medium/high-temperature thermal energy storage:based on a 200 MW-class compressed air energy storage system
摘要
Abstract
Compressed air energy storage(CAES)technologies have garnered widespread attention due to their large scale,high efficiency,and environmental friendliness.Among them,the non-combustion compressed air energy storage technology is mature,and produces no carbon emissions during operation.There are already several adiabatic non-combustion compressed air energy storage power stations in operation,under construction,and in planning in China.However,the design parameters of the CAES system lack a unified standardization system,which poses many challenges in system design and performance optimization of CAES.To solve this problem,the design of medium-temperature and high-temperature thermal energy storage system schemes for a 200 MW class CAES system is presented,the key equipment parameters and system boundary conditions are determined.Moreover,the performance and technical economy of the medium-and high-temperature thermal energy storage system schemes is compared.The results show that,the high-temperature thermal energy storage system is superior to the medium-temperature thermal energy storage system in performance indicators,but it has a higher investment cost,indicating that when choosing the thermal energy storage technology route for large-capacity CAES systems,it is necessary to consider comprehensively based on specific application scenarios and economic budgets.关键词
