  "textContent": "A dynamic frequency coordination control method for asynchronous regional power grids during wet and dry seasons is provided. By using frequency synchronous control in VSC-HVDC, frequency consistency and synchronization between the sending-end and receiving-end grids can be ensured within the range of power adjustment, enabling real-time and automatic sharing of frequency regulation resources between the two grids. Through the use of bilateral frequency limiting control in LCC-HVDC, the frequency regulation effect is enhanced, balancing frequency fluctuations between the sending-end and receiving-end grids. VSC-HVDC adaptive reactive power support control is employed to provide reactive power support to nearby LCC-HVDC, avoiding frequent operations of LCC-HVDC converter transformers and filters during frequency limiting control actions, thereby extending equipment lifespan. Furthermore, by utilizing grid-following and grid-forming control in renewable energy grid integration with additional frequency control, the frequency support capacity of renewable energy generation is improved.",
