A novel simulation method for predicting power outputs of wave energy converters

In this paper a novel transformed linear simulation method is first proposed for predicting the power outputs of wave energy converters placed in shallow water nonlinear waves. The bottom effects on the power performances of wave energy converters have also been taken into account during the calculations. The novel simulation method is based on a Hermite transformation model in which the transformation is chosen to be a monotonic cubic polynomial, calibrated such that the first four moments of the transformed model match the moments of the true process. It is demonstrated in the calculation examples that the novel transformed linear simulation method is a faster method than the traditional second order nonlinear simulation method.
