摘要(Abstract)：

随着能源集线器概念和多能协同互补思想的提出,由能源集线器之间的耦合与联接构成的能源集线器系统,对于共享、互补、经济、高效的能源传输和利用至关重要。由于气电购置量直接关系到系统的经济高效运行,其值可由系统与主网之间天然气管道和电力联络线上流过的能量来量化,但对于二者的常规约束过于保守,通过机会约束规划可以使约束具有一定的弹性,且在置信水平高于特定的置信水平时可在一定程度上保证系统的安全可靠性。基于此,在计及能源集线器内可再生能源不确定性出力下,将传统主要应用于对电力联络线交互功率的机会约束限制,延伸到对天然气管道传输功率的机会约束限制。该约束克服了常规约束保守性的问题,可调节系统气、电资源的合理分配。同时,建立电负荷需求响应模型,考虑能源集线器内各设备出力约束,以气电购置费用最小为目标,并在一定调度周期内将机会约束规划问题转化为确定性问题进行优化求解。优化结果证明对天然气管道和电力联络线上的气、电交互传输量进行机会约束限制会对能源集线器系统向主网的气电购置费用产生影响,并且重点讨论了分别对电力联络线交互功率和天然气管道传输功率实施机会约束限制以及不同置信水平参数设置对气电购置结果的影响。
