This paper studies a new approach, secondary voltage control, to improve voltage stability. In this work, thestructural model of secondary voltage control is derived. This model is very simple and has clear physical interpretation. Anested clustering algorithm to decide the partitioning of secondary voltage control areas is studied. This algorithm is based ongraph theory and needs no eigenvalue analysis, hence it has very fast computational speed. Besides, the natural nestingcharacteristic of this method can further speed up the computation. The comparison of this algorithm with the conventionalones proves its validity.
