Comprehensive Control Strategy of Energy Storage Systems for Power Grid Frequency Regulation
Although energy storage systems (ESSs) have drawn attention in power system auxiliary services due to their flexibility and rapid control, they have a small capacity compared to the system capacity. Moreover, effective management of the limited capacity in PFR requires more effective control strategies.
Frequency Control in a Power System
Primary Control. The primary control (or frequency response control) is an automatic function and it is the fastest among the three levels, as its response period is a few seconds. When an imbalance between generation and load occurs, the frequency of the power system changes. For example, with a load increase, the generated power

Frequency Regulation
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.
