Embodiment Construction
[0056] In order to better understand the present invention, the present invention will be further described below in conjunction with the examples and accompanying drawings, and the following examples are only to illustrate the present invention rather than limit it.
[0057] In this embodiment, an equivalent modeling method for DFIG wind farms that takes into account auxiliary frequency regulation services is aimed at the common power grid frequency regulation transformation scheme that DFIG asynchronous wind turbines participate in service frequency regulation services. The influence of the input wind speed of the fed asynchronous wind turbine on the working mode of the auxiliary frequency regulation service of the unit itself, according to the input wind speed, the specific working method of the wind turbine participating in the auxiliary frequency regulation service is judged, and then, the different auxiliary frequency regulation service working methods are used as the divi...
