Compensation mechanism of electrochemical energy storage power station

Can energy storage power station be strategic charged?

In the 1–4 and 14–15 periods, the energy storage power station can be strategic charged to supplement the electricity consumed by its own discharge so that it can fully participate in the frequency modulation market and obtain the frequency modulation income.

What is energy storage transaction decision model?

According to the transaction framework, a two-layer transaction decision model of energy storage participating in electric energy market and frequency modulation market is constructed. The upper model is the energy storage power station transaction decision model, which is used to generate the optimal bidding strategy of each power station.

How Auxiliary Service of energy storage is realized?

In the case, the auxiliary service of energy storage to the power grid is mainly realized through the peak regulation of the power grid. The peak-valley price difference between various regions is about 0.36–1.06 ¥/kW·h, while the unit capacity price of sensible heat energy storage is generally 170–260 ¥/kW·h [ 36 ].

What is the frequency modulation capacity of energy storage power station?

Under the conventional strategy, the frequency modulation capacity provided by the energy storage power station accounts for 74.89% of the total frequency modulation capacity demand of the system, and the frequency modulation mileage accounts for 82.37% of the total demand.

Can energy storage power station bid successfully?

In the spot market environment, in the process of energy storage as an independent subject participating in market transactions, the bidding strategy of energy storage power station will become the key to whether it can bid successfully and obtain benefits [13, 14, 15].

When do energy storage power stations charge?

As can be seen from Fig. 4, under the conventional strategy, the energy storage power station charges during 0–4 and 13–17 periods when the energy demand is low and shares the demand with the conventional unit in the rest periods.
