AGC systems automatically adjust the output of power plants to stabilize the frequency. These systems can increase or decrease the generation of electricity within seconds to counteract deviations. Batteries and other energy storage systems can quickly discharge or absorb energy to help balance the grid.
What is frequency regulation?
Frequency regulation is the process of balancing the supply and demand of electricity to maintain this consistent frequency. Frequency regulation involves real-time adjustments to the power grid to counteract fluctuations in electricity supply and demand. Here’s a closer look at how this process works:
How does distributed generation affect power system regulation?
Increases in distributed generation (DG) have similar impacts on power system regulation capability. While distributed generators typically do not impose additional regulation burdens, they are typically not capable of supplying regulation themselves. Microturbines do not follow load well.
Why is frequency regulation important?
Deviations from the standard frequency can lead to energy losses, equipment damage and even widespread blackouts. Frequency regulation is the process of balancing the supply and demand of electricity to maintain this consistent frequency.
Why do storage systems need a duty cycle?
Based upon price, the faster response services are more attractive services for storage to supply. The shorter deployment times are also better matched to the capabilities of many storage systems. However, the high cycling requirements associated with regulation may limit some storage technologies; hence, the duty cycle must be considered. Table 3.
