The purpose of this study is to determine the optimal parameters for a control strategy of an oscillating body type wave energy converter (WEC) for a WEC development and demonstration project in Japan. We plan to use a reactive control strategy for calm sea states, because wave heights in the seas near around Japan is about 1 m in summer. We also developed a combined and tuned control strategy with both reactive and resistive controls, in which the control parameters are changed to sea states. The proposed control system achieves both better performance and safer operation. In this numerical study, we determine the control parameters for the sea states by the time-domain simulation using the Newmark–β method.

When concrete examination towards utilization is needed, it is necessary to estimate the safety and the performance of a floating Oscillation Water Column (OWC)-type wave energy converter under abnormal oceanographic phenomenon such as large waves, wave impact force, deck wetness and complex motion of mooring system. Therefore, to choose a proper numerical method is important. This present paper describes a fundamental study about estimation of safety and performance of floating OWC-type wave energy converter using the two-phase flow MPS method. In this research, firstly, new algorithm is installed in order to solve problems of the two-phase flow MPS method. Secondly, applicability to an response analysis of a wharf installation type OWC-WEC of the improved MPS method is examined by wave pressure acting to the OWC-WEC and response in the air chamber of the OWC-WEC.
