所以，在系统没有任何其他附加储能的情况下，可以利用风电机组自身的有功控

Therefore, when the system does not have any additional energy storage, the active power control of the wind turbine can be used to adjust the active power output, so that it can participate in the frequency modulation of the system together with the synchronous generator in the system, thereby improving the frequency modulation ability of the system. At present, the research and application of wind power participating in power system frequency regulation are mostly variable-speed wind turbines based on doubly-fed induction generators, because doubly-fed induction wind turbines have a relatively wide operating range and can provide sufficient rotational kinetic energy to participate in the system Frequency adjustment, meanwhile, doubly-fed variable speed wind turbine is the mainstream model in the field of wind power, and this model is also an important choice for the trend of large-scale wind turbine unit capacity. Nowadays, the research on frequency control of doubly-fed induction wind turbines mainly includes power reserve control and rotor kinetic energy control.

Therefore, in the absence of any additional energy storage in the system, the wind turbine unit's own effective control can be used to achieve the effective adjustment, so that the system with the synchronous generator to participate in the system's FM, thereby improving the system's FM capacity. At present, the research and application object of wind power participation in power system frequency regulation is mostly variable speed wind turbine based on dual feed induction generator, because the speed of dual feed induction wind turbine is relatively wide, can provide more full rotational dynamic energy to participate in system frequency regulation, at the same time, double feed variable speed wind turbine is the mainstream model in the field of wind power, this model is also an important choice for the trend of large-scale wind turbine capacity. Today, the study of frequency control of dual-feed induction wind turbine mainly includes power backup control and rone dynamic energy control.

Therefore, in the absence of any other additional energy storage in the system, the active power control of the wind turbine can be used to realize the regulation of active power output, so as to participate in the frequency regulation of the system together with the synchronous generator in the system, so as to improve the frequency regulation ability of the system. At present, the research and application object of wind power participating in frequency regulation of power system are mostly variable-speed wind turbine based on doubly fed induction generator. Because the speed range of doubly fed induction wind turbine is wide, it can provide sufficient rotational kinetic energy to participate in frequency regulation of power system. At the same time, doubly fed variable-speed wind turbine is the mainstream model in the field of wind power It is also an important choice for the trend of large-scale single unit capacity of wind turbine. Nowadays, the research on frequency control of DFIG mainly includes power reserve control and rotor kinetic energy control.<br>
