摘　　要：大规模风电持续并网显著影响大电网运行的频率安全性和经济性,为此,提出一种考虑系统频率安全及场间风能转移的风电场协同规划与运行方法。首先,考虑风电场场间出力相关性,构建场间风能转移模型。其次,基于风机综合惯性控制与减载运行策略,建立了风机参与调频的系统频率响应模型,并据此制定了系统频率最大偏差约束条件。进而,设计了考虑系统频率安全及场间风能转移的风电场协同规划与运行方法。基于IEEE 30节点系统算例分析表明,所提风电场规划方法能够提高风电场风能利用率,保证系统频率安全稳定。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.
