摘要:

天然气分布式能源系统具有清洁、高效、安全、环保的特点,近年来被大力推广示范。天然气分布式能源系统用户复杂,负荷波动大,蓄能系统具有很好的削峰填谷、平衡负荷的作用,在分布式能源站中配置一定规模的蓄能系统,能够优化系统的运行策略,提高能源站的经济性。以上海某楼宇型分布式能源站供冷方式为研究对象,建立了冰蓄冷方案和水蓄冷2种配置方案,并对比分析了方案的运行模式和经济性。通过分析可知,水蓄冷方案由于采用了余热蓄冷方式,年均综合利用率可以达到83.2%,较冰蓄冷方案系统简单可靠,经济性好,可行性强。

Abstract:

The natural gas distributed energy station has been vigorously promoted and demonstrated in recent year due to its characteristics of clean, high efficiency, safety and environmental protection. The users and load of natural gas distributed energy system are complex and changeable. The energy storage system has a good function of cutting peaks , filling valleys and balancing load. A certain scale of energy storage system can be deployed in the distributed energy station, which can optimize the operation strategy and improve the economics of the system. It takes the cooling supply method of a building type distributed energy station in Shanghai as the research object, and establishes two cold storage schemes which are ice storage scheme and water storage scheme. According to the operation mode and economy analysis, the water storage scheme that adopts waste heat to storage has an 83.2% annual comprehensive utilization rate on average.It is more economical and feasible than the ice storage scheme.
