Stochastic interval stability analysis of power systems under small random excitation

  • Received Date: 2020-07-23
  • A stochastic uncertain dynamic model was put forward for power systems with asynchronous wind turbines. Based on the stochastic differential equation,matrix theory and other related theories,a Lyapunov function was constructed according to the probability stability theorem,and the stochastic small disturbance interval stability of the asynchronous wind turbine with parameter perturbation was analyzed by differential operator. Simulation results verified the validity of the proposed probabilistic stability theorem for power systems with parameter perturbation.
