Abstract
The instantaneous power and average power of the flap-type wave energy converter in irregular waves were calculated in MATLAB/Simulink to solve the Cummins equation. The effects of linear and nonlinear power intake systems were considered in analysis. The comparison between the numerical results under the linear assumption and the experimental data verifies the accuracy of the present numerical model. The influence of different hydraulic parameters on the electrical generation was studied using flap-hydraulic model. It can be concluded that there is optimum value of piston area to achieve maximum electrical power in specified wave condition.
