Frequency Regulation, or simply 'regulation', is the process of ensuring 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 in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
Frequency regulation has played a large role in energy storage commercialization, and will continue to play a role. But how large a role depends on changes to the design of PJM's frequency regulation market. PJM embarked on these changes in an effort to correct observed problems in the market.
