The demand of frequency modulation can be divided into five zones as follows: 1. To avoid frequent charging and discharging of the BESS, a dead band must be set. When the ∆ f $unicode{x02206}f$ is between ∆ f 1 $unicode{x02206}{f}_{1}$ and − ∆ f 1 $-unicode{x02206}{f}_{1}$, it means that the frequency of the node is in a range that …
