The paper deals with a selection of potentially critical contingencies from the voltage stability view-point. Consideration of all contingencies is impractical. Before contingency analysis starts, one can state, that certain contingencies need not be taken into account. In the paper, after a short overview of the existing papers, in which the problem of the selection of contingencies is considered, the new method for selection of contingencies is presented. A selection of contingencies is based on results of testing of possible power transfers in a power network after the contingencies occur. During the tests, assessments of extreme values of active and reactive power flows, which change when power system state changes, are taken into consideration. In the paper, a computational example of utilization of the described method is given. At the end, the most important features of the method are pointed out.Downloads
