On the robust performance analysis of coastal wave energy converters

A new transformed linear simulation method is first proposed in this article for the robust performance analysis of coastal wave energy converters. The influences of the bottom effects on the performances of coastal wave energy converters have also been considered during the calculations. The essence of the transformed linear simulation is to obtain the transformation G relating the non-Gaussian process and the original Gaussian process based on the equivalence of the level up-crossing rates of the two processes. In this paper the level up-crossing rates are calculated by using an asymptotic analysis approach. The accuracy and efficiency of the proposed transformed linear simulation method have been convincingly verified by the calculation examples in this paper.
