摘要：With the increase of wind power and the construction of UHVDC transmission, the wind turbines must actively participate in the system frequency regulation through inertia response and primary frequency regulation to ensure the safe and stable operation of the power system. However, the wind power penetration rate and the grid structure of each regional power grid are different, so that the corresponding power grid codes are also slightly different. Firstly, this paper introduces the specific requirements of wind power grid guidelines in typical countries and regions, and with reference to the experience of international frequency regulation codes, it puts forward the proposed implementation mode of active support new energy frequency regulation suitable for domestic power grid, and the recommended parameter for wind farm frequency regulation. Secondly, this paper summarizes the frequency modulation implementation schemes of the main wind turbine manufacturers in the world, and demonstrates the potential frequency modulation capability of the wind turbine. Finally, the challenges and realizable solutions of virtual inertia and primary frequency regulation of wind farms are prospected, and some suggestions are given.
