As shown in Figure 9, the maximum frequency excursion, maximum ROCOF, and the system frequency of the steady state of no control scheme are 59.498 Hz, −0.297 Hz/s, and 59.838 Hz, respectively. In the proposed scheme with γ = 5, they are improved to 59.581 Hz, −0.288 Hz/s, and 59.825 Hz, respectively (see in Table 1 ).
