摘　　要：An offshore wind-wave hybrid platform could consistently and cost-effectively supply renewable power.A multi-objective optimization process is proposed for a hybrid platform with hydrodynamic coupling interaction.The effects of various critical structural parameters,spacing values,and wave directions are studied for higher energy capture and offshore platform stability.Approximation models of various key parameters are established to optimize the hybrid system,with the objects of the power capture width ratio and the stability index of the platform.The optimization results are affected by the hydrodynamic coupling interaction,with a tendency to affect the higher frequency of hydrodynamic performance in the hybrid system.After the optimization,an appropriate spacing value effectively improves energy capture performance.The optimal array distance D_(Ff),D_(Fp),the optimal structural parameters R_(p),r_(p),d_(f),r_(f),and B_(PTO)are 11.57,12.75,5.1,3.3,1.5,6.5 m,and 80436 Nm s^(-1),respectively.The peak value of the wave energy converter capture width ratio in the hybrid system increases by almost 50%,with a 54%decrease in the stability index.
