Ashgabat pumped storage power station

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.

What is pumped Energy Storage?

The PSPS is the best tool for energy storage. The pumped storage has the function of energy reserve, and it solves the problem of electricity production and consumption at the same time, and not easy to store. Thus, it can effectively regulate the dynamic balance of the power systems in electricity generation and utilization.

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.

What is the storage capacity of pumped pond in Gangnan?

There is a pumped storage unit with the installed capacity of 11 MW. This PSPS uses Gangnan reservoir as the upper reservoir with the total storage capacity of 1.571×10 9 m 3, and uses the daily regulation pond in eastern Gangnan as the lower reservoir with the total storage capacity of 3.5×10 6 m 3.

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.
