摘    要:文章针对区域多能互补系统协调供应问题开展了不同供能方案的对比分析。首先,提出了燃气机组冷热电联供(combined cooling heating and power,CCHP)系统和环境源热泵系统2种分布式供能方案,制定了相应的运行策略,分析了不同供能方案的安全性和环保性;其次,建立了概率全寿命周期成本(life cycle cost,LCC)模型,给出了燃气机组冷热电联供系统、环境源热泵系统和传统供能系统3种供能方案的经济性计算方法;最后,以北方某市的商业区域为例,评估3种供能方案经济性,并通过灵敏度分析得到了天然气价和电价对不同供能方案经济性的影响。结果表明随着天然气价和电价的变化,经济性最好的方案发生变化,因此实际工程中应结合规划区域的具体内容和当地能源价格,合理选择供能方式。

关 键 词:分布式供能  燃气机组  冷热电联供(CCHP)  环境源热泵  经济性  灵敏度

Abstract:In view of the coordinated supply problem of regional multi-energy complementary systems, this paper compares and analyzes different energy supply schemes.Firstly, we propose two distributed energy supply schemes: the gas turbine combined cooling heating and power (CCHP) system and environment-source heat-pump system, develop the corresponding operation strategy, and analyze the safety and environmental protection of the different energy supply schemes.Secondly, we establish a probabilistic life cycle cost (LCC) model, and present the economic calculation method of three energy supply schemes of gas turbine CCHP system, environment-source heat-pump system and traditional energy supply system.Finally, taking the commercial area of a city in the north as an example, we compare the economic efficiency of the three energy supply schemes, and obtain the the impacts of natural gas price and electricity price on the system economy through the sensitivity analysis.The result show that with the change of natural gas price and electricity price, the best economic scheme has changed, so the actual project should be combined with the specific content of the planning area and local energy prices, and the reasonable choice of energy supply system.
Keywords:distributed energy supply  gas turbine  combined cooling heating and power (CCHP)  environment-source heat-pump  economy  sensitivity
