Research Status and Development Trend of Wind-Wave Co-development Technology

The demand for energy from the economic growth of coastal cities has entered a new stage, and it is urgent to vigorously develop offshore renewable energy and promote the green transformation of energy structure. Among the current offshore renewable energy sources, wind energy technology is more mature and has entered commercial development, but is constrained by cost factors; wave energy, as a symbiotic resource to offshore wind energy, plays a synergistic effect through wind-wave co-development to reduce costs and increase efficiency, and improves the stability of power generation. The main research objectives are to establish a mutually beneficial and win-win co-development patterns and to develop safe, efficient, and low-cost co-development set of devices, due to the wind-wave co-development technologies have not yet converged. The development trend of wind-wave co-development is large-scale array development based on the offshore wind farms. In order to fully grasp the prospects of offshore wind-wave co-development and accurately get hold of the technological research progress, the current situation and demand of wind-wave power generation is taken as the starting point, the synergistic effects of co-development is reviewed, the main types of set of devices, technical forms, and engineering examples are introduced, and the outlook on the development trend of wind-wave co-development technology is made in this paper.
