Embodiment Construction
[0073] The present invention will be further described below in conjunction with specific embodiments.
[0074] See figure 1 As shown, the wind farm inertia frequency modulation method provided in this embodiment can be used on an energy management platform or a VSG virtual synchronous generator control platform. The method is mainly based on the existing primary frequency modulation (that is, with pitch frequency modulation). Combination of control), increase inertia frequency modulation, and perform compound control of the two, which specifically includes the following steps:
[0075] 1) Communication obtains the parameter information of wind farms and wind farms, including collecting the information of the grid connection point, the unit information in the main control of the wind turbine and the parameter information set by the user.
[0076] 2) Determine whether the wind farm has the function of primary frequency modulation and whether it enters the frequency modulation mode, a...
