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.
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.
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.
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.
It is a tool for power conversion and reserve. At present, the comprehensive efficiency of the PSPS is about 75% (the ratio of power generated to power consumed) in China, which is also called "using 4 degrees to produce 3 degrees”. The PSPS is the best tool for energy storage.
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.
