The proportion of wind power generation in the power system is generally described by the wind power penetration rate. As the scale of wind farms becomes larger and larger, the proportion of installed wind power capacity is also increasing. After being connected to the system, the frequency regulation problem of the power grid has been exacerbated. With the continuous increase of wind power penetration rate, the grid-connected wind turbines have a greater impact on the total inertia of the system, which is not conducive to the stability of the grid frequency. In addition, a lower wind power penetration rate has less impact on the fluctuation of the system frequency based on wind turbine output, and the system itself can self-regulate and recover; while a larger wind power penetration rate will have a greater impact on the stability of the system frequency. influences. Therefore, the wind power penetration rate directly affects the power system's frequency regulation effect.

The proportion of wind power in power systems is generally described by wind penetration. With the increasing scale of wind farms, the proportion of installed capacity of wind power is also getting higher and higher, and the frequency regulation of the power grid is aggravated by its access to the system. With the increasing permeability of wind power, the grid-connected wind turbine has a great influence on the total inertia of the system, which is not conducive to the stability of the grid frequency. In addition, the lower wind power permeability has less effect on the fluctuation of the frequency of the system based on the fan power output, and the system itself can self-regulate and recover, while the larger wind power permeability will have a greater impact on the stability of the system frequency. Therefore, the size of wind power permeability directly affects the effect of power system on frequency regulation.

The proportion of wind power generation in power system is generally described by wind power penetration. With the increasing scale of wind farms, the proportion of wind power installed capacity is also higher and higher, which aggravates the frequency regulation problem of power grid. With the increasing of wind power penetration, the wind turbine grid connected has a greater impact on the total inertia of the system, which is not conducive to the stability of power grid frequency. In addition, low wind power penetration has less impact on the fluctuation of system frequency, which is mainly based on the output of wind turbine, and the system itself can self adjust and recover; while large wind power penetration has a greater impact on the stability of system frequency. Therefore, the permeability of wind power directly affects the effect of power system on frequency regulation.<br>
