چکیده انگلیسی
The stability of power systems in the uncertain environment has been increasingly concerned. The main discussion in this paper is the p-moment stability of power system under small Gauss type random excitation. By Lyapunov method, Ito isometry formula, matrix theory and so on, the p-moment stability theorem of stochastic models is proved when p is greater than or equal to 2. The previous conclusions of mean square stability are particular cases of our p-moment stability theorem. Taking a one machine and infinite bus system as a simulation example, using Euler-Maruyama numerical method, the angle curves under random excitation were simulated. The p-moment stability of the power system under Gauss type of random small excitation are verified and illustrated by simulation samples.
