摘要：
In this paper, the mechanism and aggregation method of wind and solar power participating in the system frequency process are clarified through the studies of inertia and frequency modulation modelling and frequency support capability aggregation. Firstly, based on the historical wind power and PV output data, a mathematical model describing the output characteristics of wind power and PV at the second and minute scales is established. Secondly, the relationship between the renewable energy hourly average frequency support capability and minute and second scale frequency support characteristics is analyzed. Finally, different hourly equivalent methods such as hourly average frequency support capacity (FSC) and hourly minimum FSC are compared and analyzed, and the equivalent frequency support capacity applicable to hourly planning and operation is studied. Results verify the correctness of the theoretical analysis of the relationship between renewable energy outputs and frequency response capability and the proposed aggregation model.
