“…When large-scale wind turbines are connected to the power grid through a power electronic converter, the equivalent inertia of the system is reduced, and the ability of the system to resist frequency disturbance is reduced [4][5][6]. With the improvement of the power system's wind power penetration, developed countries in Europe and North America have required that the wind turbine should have inertia response and primary frequency regulation capability.…”

“…The doublyfed induction generator (DFIG) is one of the most mature wind turbine generators. It is important to study the participation of new energy units represented by DFIG in frequency response [5]. According to the requirements of system frequency stability, it is of great practical engineering significance to analyze the impact of the DFIG control strategies on system frequency response.…”

Renewable energy units led by wind power participate in diversified control primary frequency modulation, making the frequency response modes and the setting of frequency modulation parameters more complex. This paper proposes a frequency response model of the power system which is highly penetrated by wind power based on the two mainstream control strategies of wind power that participate in primary frequency modulation. The model considers the influence of wind capture devices, maximum power point tracking (MPPT), and other complex control strategies on system frequency response. Based on this model, the calculation formulas of the maximum change rate of dynamic frequency, the lowest point of dynamic frequency, and the maximum steady-state frequency deviation of the system after fault disturbance are derived in the frequency domain. The influences of wind power permeability and two typical frequency response control strategies on system frequency stability are analyzed. On the one hand, it is found that the proposed model can fit the system frequency response better than the traditional system frequency response model. Beyond that, two control strategies are mainly aimed at the different frequency stability requirements. On the other hand, under the condition of meeting the system’s stability requirements, the paper calculates the control parameters of frequency response of the doubly-fed induction generator (DFIG). The time-domain simulation model of the improved IEEE three-machine nine-node system and IEEE 39-node system with high permeability of wind power are built. Through the different fault scenarios, the simulation results verify the effectiveness of the proposed model and the accuracy of control strategy parameter calculation.
