Calculation of the revenue of independent energy storage spot transactions

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.

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].

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.

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.

Is energy storage a good trading strategy for power system energy transformation?

The operation life is extended by 51.1%, which verifies the superiority of the trading strategy in this paper. Under the background of power system energy transformation, energy storage as a high-quality frequency modulation resource plays an important role in the new power system [1, 2, 3, 4, 5].

What is the life cycle cost of energy storage power station?

The Life Cycle Cost (LCC) of energy storage power station mainly includes investment cost Cinv and operation cost. The operation cost of energy storage generally includes operation and maintenance cost COM, scrap processing cost Cscr, power shortage penalty cost Cβ and power loss cost Cα. Therefore, the required energy storage LCC model CLCC is
