摘　　要：针对如何平衡LNG储罐容量与调峰能力的问题,阐述了大型LNG接收站储罐容量与调峰方式的关系。以某LNG接收站为例,对增加罐容和购买现货两种方式对罐容差异和调峰能力的影响进行分析,采用动态设计模型求解现货方式,将连续用气量低于月平均用气量月差值之和作为罐容增加量。提出利用南北地区用气不均匀性时间差,加强南北地区LNG接收站资源的相互调度,可以提高调峰能力和灵活性,充分发挥LNG接收站调峰能力的新思路。The paper presents the balance between tank capacity and peak shaving capacity of a large-scale LNG receiving terminal. Taking the specific LNG receiving terminal as an example, impacts of incremental tank capacity and purchase of spot stocks on tank capacity and peak shaving capacity are analyzed. By using a dynamic design model for solution of spot stocks procurement, total differences in months when the monthly gas consumption is consecutively lower than the average monthly consumption is taken as the increment in tank capacity. It is proposed that the uneven gas consumption in northern and southern areas in different season is considered to intensify the maneuvering of LNG receiving terminal in these areas, so as to enhance their peak shaving capacity and flexibility. （1 Table, 1 Figure, 6 References）
