In power systems, there are many uncertainty factors such as outputs of distributed generations and fluctuations loads. It is very beneficial to system analysis acquire an explicit function describing the relationship between these (namely parameters) states (or performances). This problem, termed parametric problem (PP) in this paper, can be solved by Galerkin method, which a powerful mathemat...
