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.

Does Gangnan hydropower station have load regulation?

For the application of the pumped storage unit, Gangnan hydropower station owns the ability of load regulation. Erenow, it can only generate seasonal power . Although the scale of this PSPS is small, it is designed reasonably and utilized appropriately. Its construction initiates the history of the PSPS development in China.

Does pumped storage power maintain grid stability?

Many countries configured a certain proportion of pumped storage power in the network to keep their grid stability. This paper introduces the current development status of the pumped storage power (PSP) station in some different countries based on their own economic demands and network characteristics.

How does a pumped storage power station work?

Pumped storage power stations can quickly switch from a shutdown state to full load operation, usually within a few minutes, to adjust the supply and demand balance of the grid.

What is a PSPS hydropower station?

1. Introduction The PSPS is a special hydropower station, which can use the electricity to pump water up to the upper reservoir when the energy demand is low, and release the water back down to the lower reservoir to generate electricity when the energy demand is high.

What is a flood control pump?

The pumps used in flood control applica-tions are often called upon to operate un-der normal weather conditions – not just in extreme flood situations. At the same time, the pumping station must be able to cope with much higher peak flows in flood situ-ations.
