摘要
对气电价格、运行时间、单位造价、一次能源利用率以及系统节能率等影响天然气分布式能源系统的关键技术经济指标进行了深入研究,经过数学推导,得到了基于天然气价格和目标电价关系的天然气分布式能源项目经济可行性数学模型。该模型全面反映了影响天然气分布式能源项目经济性的各种影响因素。应用本方法和模型,选择了两种典型的用户负荷进行了实例计算。所得结论可以为天然气分布式能源系统运行控制和相关研究提供理论依据。
Studying the key technical and economic indicators affecting the natural gas distributed energy such as na-ture gas price, electricity price, running time, unit cost, system energy efficiency and energy saving rate, etc. Established a DE project economic feasibility mathematical model based on the price of natural gas and electricity. The model reflects the comprehensive influence of various economic factors of natural gas distributed energy project impact. The paper selected two typical user load cases and use the methods and analytical models to calculate and analyze the cases. The conclusions can provide a theoretical basis for the run of natural gas distributed energy and its related research.
