Are pumped storage power plants a problem in China?

To address the problem of unstable large-scale supply of China's renewable energy, the proposal and accelerated growth of new power systems has promoted the construction and development of pumped storage power plants (PSPPs), and the site selection of conventional PSPPs poses a challenge that needs to be addressed urgently.

What is pumped storage power station (PSPS)?

The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase.

How pumped storage plants recover their capacity cost?

The operation period pricing method of capacity price can make the pumped storage plants recover its capacity cost, and the relevant income sharing mechanism can promote the enthusiasm of the pumped storage plants to participate in the power market transaction.

Can pumped storage plant promote low-carbon transformation of China's power system?

A life-cycle economic benefit model undergoing multi marketization stages is proposed. The policy impact is evaluated by simulating the approval process of capacity price. Pumped storage plant can help promote the low-carbon transformation of China's power system because of its fast response and energy time shift.

Why is demand analysis important for pumped storage in China?

And the demand analysis on the PSPS on the basis of the regional power systems was carried out at the same time. This not only avoided the limitations of the selection planning on a single site, but also made people have a systematic understanding on the development space of the pumped storage in China.

Does pumped storage plant participation in power trading increase economic benefits?

As an independent market subject, the participation of the pumped storage plant in power trading increases its economic benefits. The results verify the effectiveness of the phased price mechanism and economic accounting model designed in this paper.
