In order to validate the accuracy of the proposed method in
the paper, results of IEEE 30 Test System are analyzed. The
proposed method is implemented by the MAtlab7.0
programming language, the calculation step can refer to
chapter Ⅳ. The results can be obtained as follow.
It can be seen from the part A in figure 1, when it consider
the random disconnection of lines, the probability of the
voltage of node 9 increases a lot than it in normal operation.
In part B in figure 1, it shows when taking into account
the correlation among the nodes the probability of node 17
exceeding its own limitations increases great.
