This paper first gives a brief survey over four existing evaluation techniques, i. e., recursive convolution technique, fast Fourier tra. nsfornl, Fourier expansions approximation and Gram-Charlier expansions for reliability indices, and then makes a fair comparison by using both test systems and the practical power systems for the evaluation of the loss of load probability (LOLP), expected unserved energy (EUE) from the viewpoint of both accuracy and computation time.
