人们对共同开发各种类型的海洋能源越来越感兴趣，因为它可以减少电网连接和维护成本并提高电力生产。这项工作的三个目标如下：i）利用长期数据研究中国南方沿海地区海上风能和波浪能的潜力、互补性和协同性以及两种资源之间的相关性； ii) 考虑特定的海上风力发电机（OWT）和波浪能转换器（WEC），分析风浪联合开发的效益； iii) 提出一个新的指数来确定共同开发风浪项目的适宜性。结果表明，北部湾和台湾海峡两种资源的相关性最高，而浙江沿海的相关性最低。另一方面，台湾东部海域与浙江沿海的协同效应最高。此外，定量和定性分析表明，与单独运行的OWT/WEC相比，组合装置在低相关性和高协同性的区域产生更少的可变功率输出和零产量。建议未来联合开发的最佳地点位于浙江沿海，每个 SWT-6.0-154 和 6 MW Wave Dargon 组合装置每年可发电近 40 GWh。
There is an increasing interest in co-exploiting marine energies of various types, as it can reduce grid connection and maintenance costs and enhance electricity production. A threefold objective of this work is as follows: i) investigate offshore wind and wave energy potential, complementarity & synergy, and correlation between the two resources in southern China's coastal region using long-term data; ii) analyze the benefits of wind-wave joint exploitation considering specific offshore wind turbine (OWT) and wave energy converter (WEC); and iii) propose a new index to determine the suitability for co-developing wind-wave projects. The results show that the Beibu Gulf and Taiwan Strait experience the highest correlation between the two resources, in contrast to the Zhejiang coast that exhibits the lowest one. On the other hand, the east waters of Taiwan and Zhejiang coast have the highest synergy. Moreover, quantitative and qualitative analysis shows that the combined device generates less variable power output and zero production in the areas with low correlation and high synergy than the OWT/WEC operating alone. The suggested best sites for future joint exploitation are along the Zhejiang coast, with the potential of generating nearly 40 GWh/year per combined device of SWT-6.0-154 and 6 MW Wave Dargon.
