摘要
在共同建设低碳社会,加快能源转型,实现“双碳”目标形势下,为解决我国能源结构调整等各类问题,区域综合能源系统成为满足我国生态工业园区电力、供冷和供热需求的合适方案。区域综合能源系统由燃气轮机子系统、余热锅炉及汽轮机子系统、太阳集热发电子系统和氨水余热吸收制冷子系统组成。通过采用能量分析法和㶲分析法进行经济性评估,该系统输出电量为765.00MW,输出冷量为11.70MW,能源利用效率达63.15%。区域综合能源系统的经济性优于分供式系统,在未来有着很大的发展前景。
In the context of jointly building a low-carbon society,accelerating energy transition,and achieving the goal of Carbon Peak and Carbon Neutrality,regional integrated energy systems(RIESs)have emerged as a suitable solution to address various challenges,including the adjustment of China′s energy structure,catering to the electricity,cooling,and heating needs of ecological industrial parks in China.A RIES comprises subsystems such as gas turbine,waste heat boiler and steam turbine,concentrated solar thermal power generation equipment,and ammonia absorption refrigeration equipment.Through the use of energy analysis and exergy analysis for economic evaluation,it demonstrates the system outputs 765.00 MW of electricity,and 11.70 MW of cooling capacity,with an energy utilization efficiency of 63.15%.The economic viability of the RIES surpasses that of distributed systems,signifying substantial development prospects in the future.
