[0002] The ocean is a basic component of the global life support system and a valuable asset for achieving sustainable development. Developing and utilizing new clean energy is the only way to achieve sustainable development and environmental protection, and rational development of marine resources is an inherent requirement for achieving sustainable economic development.

[0003] Offshore wind power construction costs are high, and offshore wind power generation is affected by wind speed, with large fluctuations in power generation. Generally, during the offshore window period, the wind speed is low, and the wind turbine is basically in a shutdown state. Therefore, how to fully utilize the offshore wind power platform, improve the power generation efficiency, improve the economy, reduce the power fluctuation, reduce the impact on the power grid, and improve the safety of the power grid is of great significance to the entire wind farm. In order to solve the above problems, different types of new power generation structures are proposed, and the wind-solar comprehensive structure is one of the important structures. The wind-solar comprehensive power generation structure can utilize solar energy and wind energy at the same time, improving the power generation efficiency and improving the economy. Then, after most of the current offshore wind power platform structures are added with solar power generation devices, due to the existence of solar panels, the overall structure's extreme wind and wave resistance performance is reduced, and the safety performance of the structure is reduced. In addition, the area of the solar panels laid by the current structure is limited, and the wind power foundation platform cannot be well utilized. Therefore, it is necessary to upgrade and transform the existing structure, propose a new wind-solar comprehensive power generation structure, improve the power generation efficiency of the wind-solar comprehensive structure, and ensure the safety of the overall structure.
