What is the bidding strategy of Bess in the frequency regulation market?
Aiming at the multi time scale clearing mechanism in the frequency regulation market, this paper divides the bidding strategy of the BESS participating in the frequency regulation market into two stages: the day ahead market (DAM) and the real time market (RTM).
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 is the time scale of frequency regulation market?
At present, the time scale of frequency regulation market in most countries and regions can be divided into DAM and RTM . In the DAM, the grid operator announces the next day forecast frequency regulation demand, and the power generators participating in the frequency regulation market declare their supply function curves.
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.
Why is Bess set to only participate in the frequency regulation market?
Since the revenue of frequency regulation market is generally higher than that of energy market, the BESS is set to only participate in the frequency regulation market in this case, that is, its maximum declarable frequency regulation capacity is selected according to the rated power.
What is the real-time output of Bess in frequency regulation market?
Usually the real-time output of BESS in the frequency regulation market is less than its bid-winning capacity. Taking PJM market as an example, the real-time RegD signal is a normalized instruction, and its value ranges from −1 to 1. The value multiplied by the bid-winning capacity is the real-time output of the BESS.
