Curve 1 indicates that when the system has no spare capacity, the system frequency drops to a new stable frequency. Curves 2,3 indicate that when the system has spare capacity, the frequency fluctuates to the new stable frequency. The frequency fluctuation process is related to the load regulation coefficient, and in the dynamic process of frequency change, the oscillations between the units gradually converg to reach a new stable frequency. Therefore, in the dynamic process of frequency change, there are some differences between the frequency of each unit and the frequency of the system, while the frequency of each unit is more different.
