Abstract: Power system partitioning is the key of voltage and reactive power control in the present large network. This paper analyses the shortage of electric distance and defines Euclidean-distance reflection function with consideration of the effect on electric distance by reactive power at other nodes. Different partitioning point leads to different results, and different effect on system stability as well. In view of this, the paper proposes that it is the best to partition at critical point of voltage stability, and support this viewpoint with the concept of set. Statistic F and method of perturbation are used respectively to evaluate the partitioning results, and both verify the feasibility and validity of the viewpoint of partitioning at critical point of voltage stability.
