Propagating Uncertainty in Power System Dynamic Simulations Using Polynomial Chaos
TLDR
We present two uncertainty quantification approaches using polynomial-chaos-based methods that are able to reduce the computing time by three orders of magnitude compared with Monte Carlo methods while achieving the same accuracy. Expand
