Contingency analysis (CA) as an inherent function of system security assessment is critical for detecting underlying problems in a power system. More frequent CA computation is required in the deregulated power markets to monitor the state of the system under " what if " situations in view of the fact that the power systems are now operated closer to their(More)
An intrusive spectral method of probabilistic load flow (PLF) is proposed in the paper, which can handle the uncertainties arising from renewable energy integration. Generalized polynomial chaos (gPC) expansions of dependent random variables are utilized to build a spectral stochastic representation of PLF model. Instead of solving the coupled PLF model(More)
