Abstract
According to the uncertain characteristics of random variables injected into a practical power system,an as?sessment method for static voltage stability probability is proposed considering the conventional generators'fault,load fluctuation and wind power random output.Under the premise that the probability distribution of each injected random variable is known,through calculating the sensitivity matrix of static voltage stability critical point with respect to the system's stochastic parameters,the stochastic characteristics of the critical point's position are determined by studying the variation of random parameters which areclosely related to the position.Besides,the probability distribution is ob?tained by the expansion of Gram-Charlier series.The proposed method is tested on an IEEE 39-node system.Simulation results show that the proposed method can better reflect the influence of injected random variables on the static voltage stability,and it also has less computation load.关键词
