Monrovia base power pumped storage power station project

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.

What is reversible pumped storage unit (PSPS)?

The PSPS is both the load and power source. The reversible pumped storage unit is used as a pump to consume the temporarily surplus power when the energy demand is low. On the contrary, the unit can run as a generator when the energy demand is high. This is not possessed by any other type of power plants.

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.

Should Chinese power systems develop pumped storage systems?

The result shows the urgency of developing the PSPS in Chinese power systems that have given priority to thermal power, and the energy resources need the wide-range optimal allocation within the system. The development cycle of the pumped storage is long, and at least 8–10 years are needed from the planning to the completion.

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.

How are pumped storage units different from conventional hydroelectric generating sets?

In fact, the main equipments of the pumped storage unit, including the pump turbine and motor generator, are basically the same with the conventional hydroelectric generating sets. They are only different in that the operation condition of the former is more complex, and the automatic control components account for a larger proportion.
