In this paper , the optimizations of buoy shape and array geometry are studied to improve the energy ab-sorption efficiency of direct-drive wave energy converter ( DDWEC ) and to smooth the output power fluctuations . The hydrodynamic model of DDWEC is derived and analyzed , therefore , the optimization rules of hydrodynamic pa-rameters are summarized .Based on the rules , the optimization measures of buoy shape are proposed , and then the hydrodynamic software WAMIT is used to simulate and verify the improvement of the energy absorption efficiency . Meanwhile , considering buoys interactions , the array geometry of wave farm is optimized to mitigate power fluctua-tions and weaken the buoys interactions ( such as shadowing effect ) , based on the optimization results of buoy shape.As a result, the energy absorption of wave farm is increased .
