摘　　要：针对湖南省某新城区的区域能源项目提出一套区域能源技术路线筛选模型,通过该模型确定采用燃气冷热电三联供+污水源热泵+管道储能+调峰备用+换热站的多能耦合区域能源系统,以能源综合利用率最高、成本最低为目标动态调整多系统之间的启停关系和运行策略。与传统空调系统方案相比,该多能耦合区域能源系统虽然增加25~45元/米^(2)的初投资,但是该系统能源综合利用率高达84.22%,夏季和冬季可再生能源利用率分别达39%和87%,投资回收期约10年,节能减排效果显著,经济效益明显。Taking a district energy project of a new city in Hunan province as an example,a set of technical route selection model for district energy is put forward.The multienergy coupled district energy system composed of gas-fired CCHP(combined cooling,heating and power),sewage source heat pump,pipeline energy storage,peak load regulation,and heat exchange station is determined by this model.Aimed at the highest comprehensive energy efficiency and the lowest cost,the start stop relationship and operation strategy among multiple systems are dynamically adjusted.Compared with the traditional air-conditioning system,the initial investment of the multi-energy coupled district energy system is increased by 25-45 yuan/m^(2),but the comprehensive energy utilization rate of the system is as high as 84.22%,the renewable energy utilization rates in summer and winter are 39% and 87% respectively,and the investment payback period is about 10 years.The energy conservation and emission reduction effect is significant,and the economic benefits are obvious.
