Abstract: | This paper proposed a new method to identify the voltage weak region - combination of the reactive power sensitivity and the whole network N-1 voltage scanning based on an analysis of the power system voltage stable and collapse mechanism. Comprehensive computation and analysis of the data of a certain provincial power grid by this method indicate that the calculated results are in the conformity with the actual conditions, illustrating that the method is systematic and highly applicable. |
