Abstract :
The order reduction for special modes of large power systems under single operating condition is presented in this paper. The system matrix is rearranged by eigenvalue sensitivities, and reduced in dimension with only the strong correlation generators reserved, the computation of the reduced system matrix is carried out by the improved rayleigh quotient inverse iteration. To improve the efficiency of power system stability analysis, it is necessary to study the application of the reduced system model and the order reduction of large power system under probabilistic conditions. So the probabilistic method is introduced in this paper. The effectiveness of the proposed approach is demonstrated on two testing systems.
