It can be seen from Figure 6 that V first increases and then decreases with the change of the capacity ratio of BESS for frequency regulation. When the ratio is 60%, V is maximum v, and its value in scenario 2 is larger than that in scenario 1.

To solve the above problems, an auxiliary energy storage system (ESS) has been widely used to provide frequency support with the rapid development of energy storage equipment.

Frequency Regulation (or just "regulation") ensures the balance of electricity supply and demand at all times, particularly over time frames from seconds to minutes. When supply exceeds demand the electric grid frequency increases and vice versa. It is an automatic change in active power output in response to a frequency change.

In contrast, advanced energy storage systems are ideally suited for providing frequency regulation services. Since the ACE represents the short-term fluctuations in supply and demand, it is by-and-large energy neutral—over a measureable amount of time, an asset providing regulation service neither generates nor consumes
