JOINT CORRELATION ANALYSIS OF WIND AND WAVE ENERGY IN TAIWAN STRAIT CONSIDERING OCEAN MOTION UNDER TYPHOON ENVIRONMENT
Given the abundant wind and wave energy resources along the southeast coast of China,considering the coupling between wind,waves and currents in the marine environment,and proposing a reasonable method for analyze the interaction between wind energy and wave energy in typhoon conditions is particularly important.Based on the secondary development of MCT coupler,the WRF-SWAN-FVCOM simulation method considering ocean movement during the whole process of typhoon transit is proposed in this paper,and the real-time coupling simulation of wind-wave-current during the whole process of Typhoon"Meranti"transit is reproduced.The spatio-temporal distribution,difference and variability of wind energy and wave energy in the Taiwan Strait during typhoon and typhoon-ocean movement coupling are compared and analyzed,and the influence of ocean movement on the joint correlation of wind energy and wave energy in the Taiwan Strait is revealed.The results show that considering ocean motion,the simulation results are more accurate,and the accuracy of maximum stable wind speed is improved by 11.5% .Considering the ocean movement,the wind and wave can be more stable,and the wind power density increases by 34.19% and wave power density increases by 42.27% .Considering that the ocean movement improves the joint correlation of wind and wave in the Taiwan Strait region,the wind and wave combined power generation should be fully carried out before the typhoon,and the stability of wave energy should be fully exerted after the typhoon.
