Multi-parameter Uncertainty Analysis in Power System Dynamic Simulation: A New Solution Based on the Stochastic Response Surface Method and Trajectory Sensitivity Method

Power system simulations are greatly affected by uncertainties arising from models and parameters. The conventional methods of uncertainty analysis involve many thousand rounds of computation, which are both time and effort demanding. Based on the stochastic response surface method and the trajectory sensitivity method, this article proposes a new solution to reduce the number of uncertain inputs and to expedite the calculation of uncertainty....
