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.
Frequency regulation
Typical sources of AGC include hydropower, gas combustion turbines, gas combined-cycle turbines, gas, or coal steam turbine units that are providing energy from a portion of their capacity but that have additional unused capacity. In some control areas, batteries, fly wheels, and flexible loads also provide frequency regulation.
