Wave absorber ballast optimization based on the analytical model for a pitching wave energy converter

The present paper considers pitching wave energy converters (WECs) integrated in a floating platform, e.g., foundation for wind turbine. Each WEC consists of partially submerged absorber that rotates about the hinge located above still water level under influence waves. contains separated ballast tanks are used to ensure desired initial tilting angle with respect (called rest angle). same can be achieved by filling different compartments impacts inertia moment hinge, response amplitude operator (RAO), resonance frequency absorber, and power absorption performance. exhaustive search suitable configuration quickly become computationally expensive task depending on number tanks. In this paper, optimization algorithm based an analytical model is developed. applied investigate impact ballasts angle, RAO absorber. It provides base design location improved proposed adapted other WECs.
