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].
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).
Under the premise of meeting the grid regulation demand power, the rated power and the rated climbing rate of the TPU, the rated power, rated climbing rate, and the SOC limitation of the ES station are considered as constraints, shown as (4) where is the FR demand power of the z -th AGC command. is the time interval between two AGC commands.
A regional grid with a TPU and a hybrid ES station is used to validate the effectiveness of the proposed strategy. The results show that the FR resources are stimulated to improve their performance, and thus, the frequency performance of the system is improved by the proposed strategy. 1. Introduction
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.
The frequency regulation power optimization framework for multiple resources is proposed. The cost, revenue, and performance indicators of hybrid energy storage during the regulation process are analyzed. The comprehensive efficiency evaluation system of energy storage by evaluating and weighing methods is established.
