Planning and Operation of Wind Farms Considering Frequency Safety and Wind Energy Transfer

The continuous grid integration of large-scale wind power significantly affects the frequency security and economy of large-scale power grid operation. Therefore， this paper proposes a collaborative planning and operation method for wind farms that takes into account system frequency security and inter-field wind energy transfer. Firstly， the inter-field wind energy transfer model is constructed by considering the correlation between the outputs of wind farms. Second， based on the integrated inertia control and load shedding operation strategy of wind turbines， the system frequency response model of wind turbines participating in FM is established， and the constraints of the maximum deviation of system frequency are formulated accordingly. Further， a collaborative planning and operation method for wind farms considering system frequency safety and inter-field wind energy transfer is designed. The analysis based on the IEEE30 node system example shows that the proposed wind farm planning method can improve the wind energy utilization rate of wind farms and ensure the system frequency safety and stability.
