Zusammenfassung:	A method and a device for primary frequency control in renewable energy power generation are provided. An inverter performs a first power adjustment according to a p-f droop curve before receiving a power adjustment instruction sent by the power station controller, and performs a second power adjustment in response to the power adjustment instruction. Since the inverter performs the first power adjustment before responding to the power adjustment instruction sent by the power station controller, the response of the primary frequency modulation is speeded up, so that rapid control for the renewable energy generation power is achieved, thereby ensuring stable operation of a power grid for renewable energy power generation.
