6 FAQs about [The difference between frequency regulation and peak regulation in energy storage power stations]
What is the difference between dedicated frequency regulation and peak shaving?
All dedicated frequency regulation energy storage stations are allocated solely for the purpose of frequency regulation, while all dedicated peak shaving energy storage stations are exclusively utilized for peak shaving.
Does energy storage participate in user-side peaking and frequency regulation?
The benefits of energy storage participating in user-side peaking and frequency regulation come from the electricity price difference of peaking, frequency regulation capacity compensation and frequency regulation mileage compensation. It is expressed as the following formula.
How can peak shaving and frequency regulation improve energy storage development?
The main contributions of this work are described as follows: A peak shaving and frequency regulation coordinated output strategy based on the existing energy storage participating is proposed to improve the economic problem of energy storage development and increase the economic benefits of energy storage on the industrial park.
Can small capacity energy storage power stations compete for frequency regulation services?
At present, China’s small capacity energy storage power stations cannot be allowed to compete for frequency regulation services, but the establishment of auxiliary service markets such as frequency regulation and standby is conducive to guiding investment to improve the flexibility of power systems [ 19, 20, 21, 22, 23, 24, 25 ].
Why is frequency regulation important?
Frequency regulation only requires compensating for the imbalance between power supply and demand in the grid, so its power requirement is smaller compared to the peak load. Additionally, due to the short time scale of frequency regulation, its energy storage capacity requirement is also smaller.
What is the capacity planning model of peak shaving and frequency regulation?
According to the capacity planning model of peak shaving and frequency regulation and the parameters given above, an energy storage battery with a maximum power of 1 MW and capacity of 1 MW·h was used to carry out the day-ahead peak shaving and frequency regulation planning on the user side. The obtained results are E1 = 0.8 MW·h and E2 = 0.2 MW·h.
