摘　　要：引入两种能够反映负荷水平变化的灵敏度模型,并利用启发式算法根据灵敏度调整发电机输出功率以及削减负荷需求,从而实施阻塞管理。利用关联度分析方法对各种灵敏度模型进行误差分析。最后,通过编程仿真分析了负荷水平不变及变化时不同灵敏度分析方法的误差情况。算例表明,利用本文所提的阻塞管理方法,各种灵敏度模型均能较好地消除阻塞,且在负荷水平不变和变化时,表现出较高的精度。Two types of sensitivity models which could reflect the changes in load levels are introduced and heuristic algorithm which considers the adjustment of generations and load shedding according to the sensitivity is used to solve transmission congestion. Then, grey related method is used to analyze error caused by different sensitivity models. In the end, the error situations of different sensitivity analysis methods are analyzed by programming simulation. The example shows that the sensitivity model can eliminate the blockage by the congestion management method proposed in this paper, and show the higher accuracy with load level unchanged and changed.
