6 FAQs about [Inertial energy storage startup principle video]
What is power system inertia?
Power system engineers typically describe the inertia of a generator in terms of stored rotational kinetic energy (EPRI 2019), so inertia has the same units of energy (power delivered over a period of time).
How can inertia be maintained?
Summary of Options to Maintain Frequency Stability Inertia can be maintained via operating the grid to ensure the mix of generators online exceeds critical inertia levels.22 Figure 13 showed how as both VG and load vary, power plants are turned on and off, which results in changes in the amount of inertia available.
How does inertial response affect electricity generation?
To accommodate the imbalance between supply and demand due to the drop in generation, the remaining online generators convert their rotational kinetic energy (inertia) into real power generation—referred to as inertial response. This process slows the generators and results in a drop in grid frequency.
Can an energy storage system provide inertial response and primary frequency regulation?
An energy storage system (ESS) might be a viable solution for providing inertial response and primary frequency regulation. A methodology has been presented here for the sizing of the ESS in terms of required power and energy. It describes the contribution of the ESS to the grid, in terms of inertial constant and droop.
Where can I find a report on inertia in power systems?
This report is available at no cost from the National Renewable Energy Laboratory at www.nrel.gov/publications. Inertia in power systems refers to the energy stored in large rotating generators and some industrial motors, which gives them the tendency to remain rotating.
Why is inertia important?
Grid frequency, which is a measure of the balance of supply of electricity and demand, can drop if a large power plant or transmission fails. Inertia resists this drop in frequency, giving the grid time to rebalance supply and demand. Inertia is only one of several grid services that help maintain power system reliability.
