Energy storage power station electricity price trading mechanism

The paper describes the basic application scenarios and application values of energy storage power stations in power systems, and analyzes the price design schemes of energy storage power stations, including the two-part electricity price mechanism under controlled conditions and the market-based electricity price mechanism under the market model. In May 2021, the National Development and Reform Commission released "The opinions of the National Development and Reform Commission on further improving the price formation mechanism of pumped storage plants" (NDRC Energy [2021] No.633), which proposed to adhere to the two-part electricity price of pumped storage plants, form electricity ...

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.

What is energy storage power station?

The energy storage power station under the conventional strategy participates in the electric energy market transaction for a long time, and the quotation fluctuation is small except for the peak power consumption in the evening.

Does trading strategy improve energy storage power station performance?

The result of the example showed that the return rate of the energy storage power station under the trading strategy in this paper was increased by 8.14% compared with that of the conventional strategy. The operation life is extended by 51.1%, which verifies the superiority of the trading strategy in this paper.

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].

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.
