摘要
随着社会用能需求的不断增加,对能源的清洁环保要求也不断提高。分布式冷热电三联供系统作为能源互联网中的重要组成部分,因其较高的能源综合利用效率、良好的节能性和经济性等优点在各地推广落地。通过分析上海某旅游度假区的燃气分布式冷热电三联供系统,统筹考虑系统的经济性和节能性,建立数学模型。采用遗传算法求解夏季、冬季、过渡季下的运行优化策略,对提高全国各地区三联供系统运行策略的节能性和经济性有借鉴指导意义,对分布式能源系统在各地区的推进发展具有促进作用。
In recent years, the demand for energy in society has been increasing, and the requirements for clean and environmental-friendly energy have also increased. As an important part of the energy Internet, the distributed cold, heat and power triple supply system(CCHP)has been promoted nationwide due to its high energy comprehensive utilization efficiency, excellent energy saving and economical efficiency. This paper analyzed the gas-distributed cogeneration system of a tourist resort in Shanghai, considering the economical efficiency and energy-saving of the system, established a mathematical model, then used the genetic algorithm to solve the operation optimization strategy in summer, winter and transition seasons. It can be used as a reference for improving the energy-saving and economical efficiency of the operation strategy of the triple supply system in all regions of the country. It also push ahead the development of distributed energy systems in various regions.
