Should pumped storage power station be included in the power grid?

With the development of transmission and distribution price reform in China, pumped storage power station can not continue to be included in the effective assets of the power grid, and its cost can not be dredged through the transmission and distribution price, so it is urgent to find a way to protect its own income through the market.

Should pumped storage power stations use a three-stage model?

The calculation example analysis shows that compared with the traditional model, the “three-stage” model can bring better benefits to the pumped storage power station, and when the actual value of demand fluctuates within −8%, the pumped storage power station has the ability to resist risks higher than the market average.

How does the ESM determine the power price?

For the ESM, users settle the power price according to the “day-ahead benchmark, real-time difference” principle (Ding and Tan, 2022). The power price consists of two components: the day-ahead market, which determines the power price, and the deviation power price, which is determined by the real-time market.

What is the competitive strategy optimization model of pumped storage power station?

In the competitive strategy optimization model of PSPS, the physical characteristics of a pumped storage power station need to be considered, such as the variable speed technology of the generator or pumping unit, whether there is a frequency converter, and whether it is synchronous or asynchronous motor.

Why do small-capacity thermal power units have a fixed price strategy?

At the same time, due to the lack of market power, the bidding behavior has less impact on the market, so small-capacity thermal power units are more of the receivers of the market price, adopting a simple fixed price strategy.

Is PSPS a profitable market player in eesm?

The Chinese government has put forward the target of “30.60″ for energy conservation and emission reduction. With the increase of the proportion of renewable energy, the profitability of PSPS as an independent market player participating in EESM has decreased.
