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.
Ancillary services – Frequency Regulation, in particular – has been critical to achieving desired hurdle rates among front-of-the-meter storage projects in deregulated markets. However, given finite size and price
