6 FAQs about [What is power storage frequency regulation ]

What is frequency regulation?

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.

Does frequency regulation play a role in energy storage commercialization?

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.

Why do grid operators need frequency regulation?

Because demand and supply need to be balanced almost immediately, these sudden changes necessitate instantaneous adjustments within the timeframe of seconds to minutes. So grid operators rely upon “frequency regulation” resources to correct for these small mismatches between supply and demand.

What is the difference between voltage and frequency regulation?

Voltage regulation ensures that the pressure (voltage) remains constant while frequency regulation maintains the rhythm (frequency) on the grid. Paired together, voltage and frequency ensure consumers receive a reliable and constant supply of power. Without this pairing, disruptions occur in the absence of an intervention by market operators.

Why is frequency control important in a modern power grid?
