Objective In recent years, the proportion of new energy utilization has gradually increased. This article aims to solve the problem of unstable and fluctuating sea breeze output, in order to improve the utilization rate of transmission channels.

Method Based on the Guangdong East Energy Base, using a multi energy complementary integration development model and energy storage regulation methods, a quantitative analysis was conducted on the capacity ratio of sea breeze and thermal power units. By using grid type fans, the "wind and fire bundling" was jointly sent out, and the technologies such as in-situ hydrogen production from seawater, carbon capture utilization and storage (CCUS), CO₂ synthesis into methanol were utilized to deeply explore the potential for carbon reduction and absorption. They reduced the amount of wind abandoned in sea breeze projects and fitted the bundling and delivery effect of "wind+fire+storage".

Result When the capacity ratio of sea breeze to thermal power units is 2.1∶1, it is possible to maximize the installed capacity of sea breeze without abandoning the wind, while limiting the capacity of the transmission channel. The multi energy complementary fusion development model optimizes the overall external power characteristics of the transmission channel, reduces abandoned light and wind, and improves the utilization rate of existing channels.

Conclusion Multi energy complementary integration development model plays a good demonstration role in the development of offshore wind power bases, it is the best way to send out in sea breeze scenarios. The research has certain feasibility and provides reference for similar design schemes.
