Such uncertainties will involve the assessment of the impact of uncertain variables on the control and monitoring of the future power systems. Identification and classification of influential uncertain variables are imperative for power system stability assessment in future smart grid because they provide guidance for handling uncertainty for electrical system operators for management and securing the power grid operations with efficient control and monitoring. In this paper, a probabilistic analysis methodology is proposed for the assessment of the impact of critical uncertain variables on voltage and small-signal stability using quantitative sensitivity technique. The proposed methodology is carried out with different level of penetration of renewable sources and the impacts of influential variables are treated and discussed. The proposed methodology is performed using the modified IEEE 14-bus benchmark. The performances of the probability density function graphs for stability indexes are used for assessing their sensitivities.
