- Abstract:
- The stochastic small signal stability of single machine infinite bus power systems was investigated with consideration of the relationship between the system parameters and the stochastic disturbance in this paper. Firstly, according to the three different characteristics of the eigenvalues of the system coeffcient matrix, the mean stability and mean and square stability were discussed. It was showen that if the power system was asymptotically stable under no stochastic disturbance. Its mean stable and mean were aquare stable under small stochastic disturbance. The function of the bound of mean and mean square value with respect to the variance and random perturbation relation between stochastic intensity and system parameters was given. Finally, the powersystm was simulated under different stochastic intensity and the correctness of the proposed results was verified.
