What is a battery energy storage power station (Bess)?
In recent years, battery energy storages stations (BESSs) account for the largest proportion in large-scale energy storage power station projects due to its advantages such as rapid response, high integrated power, decreasing cost year by year and short construction cycle.
What is the minimum frequency regulation capacity allowed by each power station?
This is because according to the frequency regulation market mechanism, the minimum frequency regulation capacity allowed to be declared by each power station is 1 MW. The BESS A only declared 14 MW frequency regulation capacity and left 1 MW capacity for other BESSs to win the bidding.
Is frequency regulation capacity cost a fixed value?
It can be seen from (9) that the frequency regulation capacity cost of BESS has nothing to do with its bid-winning capacity and is a fixed value, which is consistent with the current compensation mechanism of fixed price of frequency regulation capacity in some countries and regions.
How effective is the bidding strategy of energy storage power station?
The bidding strategy of energy storage power station formulated in most papers relies on the day-ahead predicted price and regulation demand, and the effectiveness of the bidding strategy is based on the premise that day-ahead forecast is accurate [9, 10, 11].
What are the advantages of energy storage?
Compared with traditional thermal power units, energy storage has the characteristics of rapid response, precise regulation, flexible control, two-way regulation and high energy conversion efficiency, which can be used as a high-quality frequency regulation resource [5, 6, 7].
Why is frequency stability important?
With the increasing proportion of renewable energy generation, the volatility and randomness of the power generation side of the power system are aggravated, and maintaining frequency stability is crucial for the future power grid [1, 2, 3, 4].
