Optimization of Combined Cooling,Heating and Power System Using Clean Energy for Low-carbon Communities

为了推动低碳社区建设,提升社区能源系统的经济性和环保性,通过构建多能互补的清洁能源联供系统,利用多种供能技术的协调互补实现社区的清洁低碳化供能。合理的设计规划和运行策略有利于发挥清洁能源联供系统可再生能源消纳率高、系统设备运行效率高的优势,本文通过TRNSYS软件建立了清洁能源联供系统的动态仿真模型,并结合双层优化模型对清洁能源联供系统进行优化。相比于常规能源系统,优化后的清洁能源联供系统可以降低20%的费用年值和25%的年CO_(2)排放量,具有显著的经济环境效益,有利于实现社区的低碳化转型。

To promote the development of low-carbon communities and establish economic and environmentalfriendly energy systems for communities,a multi-energy complementary clean energy supply system was established to realize low-carbon energy supply by coordinating multiple energy technologies.Rational planning and operation strategy are conducive to giving the advantages of a combined clean energy supply system in higher renewable energy consumption rate and higher equipment operation efficiency into play.In this paper,the dynamic simulation model of a clean energy supply system was established through TRNSYS software,and the system was optimized with a two-stage optimization model.Compared with the conventional energy system,the optimized clean energy supply system can reduce the annual cost value by 20%and annual CO_(2)emissions by 25%,showing significant economic and environmental benefits and is beneficial to realize the low-carbon transformation of communities.
