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.
