摘要: 通过建立含异步风力发电机组的电力系统随机不确定动态模型,基于随机微分方程、矩阵论等相关理论,给出系统依概率稳定定理,构造Lyapunov函数,并利用微分算子分析包含参数摄动的异步风力发电机组的随机小扰动区间稳定性.仿真结果验证了本文所提出的考虑参数摄动的电力系统依概率稳定定理的有效性.Abstract: 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.
