Configuration of Wind Power Primary Frequency Control Parameters with Frequency Security Consideration

The stochastic fluctuations in wind power output render conventional parameters configuration of frequency regulation inadequate for accurately characterizing the actual frequency regulation capability. To address this issue, this paper proposes a dynamic configuration method for frequency regulation parameters that is directly coupled with real-time output power. Specifically, a dynamic mapping model among wind speed, power output, and regulation parameters is established to enable adaptive adjustment of the parameters in response to instantaneous wind turbine output. Furthermore, by aligning power output with system frequency regulation requirements, a dynamic parameter configuration model is developed to achieve coordinated optimization between regulation parameters and transient power levels. By employing a piecewise linear approximation approach in conjunction with SOS2 constraints, the original nonlinear problem involving exponential terms is transformed into a pure mixed-integer linear programming formulation. Simulation results demonstrate that, compared to traditional capacity-based parameter setting methods, the proposed strategy significantly enhances the frequency regulation capability of wind power during primary frequency regulation and effectively mitigates secondary frequency drops.
