【摘要】 在序列运算理论基础上提出了一种用于多节点系统的随机生产模拟新算法。利用序列运算理论对系统中的各元件建模,使用概率性序列表示各元件的可用容量。针对输电元件,定义了正反两个方向的可用容量序列,进而方便地处理了不同节点间联络线上的功率流动。将随机生产模拟看做是资源与需求之间的逐次供需匹配过程,并根据资源的经济性与需求的不同可靠性要求决定其参与供需匹配的顺序。因而,该算法能够综合考虑系统经济性与可靠性要求,在满足不同可靠性要求的前提下,达到资源的最有效利用。更多还原

【Abstract】 Based on the sequence operation theory, a novel algorithm of probabilistic production simulation for a multi-area power system is proposed. All components of the power system are modeled according to sequence operation theory and then expressed as probabilistic sequences. As to the inter-region transmission component, two sequences, denoting available capacities of positive and negative directions respectively, are defined to simulate the two directional potential power flows. The production simulation is treated as successive supply-demand matching processes. The matching order of resources and demands is decided according to their economic indices and different reliability requirements. Because this algorithm can take both the system economic indices and reliability requirements into account, it can achieve the most efficient utilization of resources. Furthermore, the characteristics of sequence’s expected values can be used to simplify the calculations. The numerical sample study shows that the proposed algorithm is efficient and accurate.更多还原
