【摘要】：近年来,天然气在我国能源消费结构中所占比重逐渐增加,因季节差异造成其消费量峰谷差值日益拉大,不仅使得消费旺季时天然气供气网络负荷过重,而且也会导致消费淡季时储运网络资源的闲置浪费。为了缓解以上矛盾,从整个天然气互联网的角度出发,将天然气能源的气源、运输网络、荷载、存储过程包含在同一个系统中,在宏观层面建立了一个天然气"源—网—荷—储"协调规划模型;进而结合中国29个省市自治区1995—2016年天然气的生产量、消费量数据,以天然气系统运营总成本为评价指标,通过计算对比不同情形下的运营成本,验证了该模型的有效性。结论认为:(1)天然气直供直销情形下,气源不足时主要靠从外省购买或进口LNG来弥补,此时运营成本最高;(2)较之于前者,引入储气调峰设施不仅可以使运营成本降低,而且还可以提高天然气供应的稳定性;(3)同时引入储气调峰设施和用户需求响应,可以调节季节性天然气消费行为,进一步降低天然气系统的运营成本。借助该模型对天然气运营过程进行统筹规划,将有助于我国天然气生产供应系统的优化建设。
[Abstract]:In recent years, the proportion of natural gas in China's energy consumption structure has gradually increased. Due to seasonal differences, the difference between peak and valley consumption of natural gas is increasing day by day, which not only makes the natural gas supply network overloaded during the peak consumption season. In addition, it will also lead to idle waste of storage and transportation network resources during the off-season consumption. In order to alleviate the above contradiction, from the perspective of the entire natural gas Internet, the gas source, transportation network, and load of natural gas energy will be taken into account. The stored process is included in the same system, and a coordinated planning model of "source-net-load-storage" for natural gas is established at the macro level, and then the data on the production and consumption of natural gas from 1995-2016 of 29 provinces and municipalities in China are combined. Taking the total operating cost of natural gas system as the evaluation index, the validity of the model is verified by calculating and comparing the operating costs under different conditions. When the gas supply is insufficient, it is mainly made up by purchasing or importing LNG from other provinces. At this time, the operating cost is the highest. Compared with the former, the introduction of gas storage and peak-shaving facilities can not only reduce the operating cost. It can also improve the stability of natural gas supply and introduce gas storage peak-shaving facilities and user demand response at the same time, which can adjust the seasonal natural gas consumption behavior. With the help of the model, the overall planning of the natural gas operation process will be helpful to the optimization construction of the natural gas production and supply system in China.
