Key Technologies for Efficient Collection and Friendly Grid Integration of Large-Scale Deep and Distant Offshore Wind Power

Accelerating the development of renewable energy to gradually replace fossil energy is a necessary path to achieving carbon neutrality. Compared with onshore wind power, offshore wind power has advantages such as abundant resources and less demand for land resources, offering huge development potential. The development of offshore wind power plays a crucial role in continuously expanding the wind power installed capacity and holds a prominent position in the field of renewable power generation. The wind energy resource reserves in the deep and distant offshore areas far exceed those in the near shore regions, facilitating the construction of large-scale offshore wind farms. As the near shore wind power resources gradually reach saturation, the development of deep and distant offshore wind power will become an important direction for the future growth of the offshore wind industry.

This research topic aims to deepen the understanding and refine the technologies for large-scale deep and distant offshore wind power. Currently, most large-scale offshore wind power transmission projects adopt the point-to-point HVDC scheme, and its limitations are becoming increasingly prominent. Firstly, point-to-point HVDC scheme uses existing AC grids in coastal land areas to transmit wind power to load centers, which is transmission corridor resources demanding. Secondly, the adverse offshore conditions result in high operation and maintenance costs for offshore converter platforms. Thirdly, the integration of large-scale offshore wind power will replace some synchronous generator units, thereby reducing the frequency and voltage support for the onshore AC system. In response to these challenges, this research topic intends to conduct research from multiple aspects, to provide technical support for the development of offshore wind power in the future.
