6 FAQs about [Pumped storage power station safety accident]
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.
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 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.
Why is pumped storage a good tool for load regulation?
As to the pumped storage unit, it is the optimal tool for load regulation with the function of energy storage, as described above. In addition, it is the only kind of unit that can act as the load when the energy demand of the power network is low. Furthermore, in China, there are a large quantity of good PSPS sites to be exploited.
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 reversible pumped storage unit?
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.
