The traditional approach to frequency control in power grids involves approximating the system as a linear model based on a specific operating condition
With the continuous decrease of thermal generation capacity, battery energy storage is expected to take part in frequency regulation service. However,
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.
2. Challenges of frequency regulation in modern power systems Frequency regulation, a method for assessing grid stability following a disturbance or fault, is evaluated by considering frequency nadir, steady-state deviation, a dynamic rolling window, and the rate of
