2 Frequency Regulation Energy Storage System. This study assumes that the BESS is used for frequency regulation purposes. As shown in Fig. 1, many BESSs use a large-capacity lithium-ion battery that is connected to the system using a voltage source converter recently.
The results show that BESS as a support unit for frequency regulation can reduce the frequency nadir of the system from 49.49 Hz to 49.80 Hz. The rate of change of frequency (RoCoF) value is reduced from 0.270 Hz/s to 0.078 Hz/s. The steady-state frequency value also approaches the reference frequency value of 50 Hz from 49.80 Hz to 49.89 Hz.
In this way, the system frequency is maintained close to the specified nominal value.
