Profit analysis of pumped storage power station technology

What are the development models of pumped storage power stations?

According to the different stages of the development of the power market, this paper puts forward the corresponding development models of pumped storage power stations, which are successively the “two-part price system” model, the “partial capacity fixed compensation” model, and the “completely independent market participation” model.

Do pumped storage power stations improve economic benefits?

According to the results of sensitivity analysis, the operation of pumped storage power stations under different models is guided, to promote the improvement of economic benefits of power stations. In the selection of sensitive factors, priority should be given to the factors that have a greater impact on income.

What is the price mechanism of pumped storage power stations?

In terms of the pumped storage price mechanism, most of the existing studies focus on the price mechanism of pumped storage power stations at a certain stage, including the current two-part price mechanism and the bidding mechanism under the market environment, and the horizontal comparison of the multi-stage price mechanism is lacking.

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 to determine the operation strategy of a pumped storage power station?

When formulating the operation strategy of the power station, reference can be made to the operation data reported by the power station for the five years from 2018 to 2022. The power consumption and power generation of the pumped storage power station during this period are shown in Figure 5.

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.
