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 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 two-part electricity price be implemented in the PSPS?
In 2014, the NDRC formulated the notice about perfecting the pricing mechanism of the PSPS to speed up its exploitation . This notice confirmed that two-part electricity price should be implemented in the PSPS before the power market in China formed.
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.
Is a PSPS a good energy storage system?
Compared with them, the PSPS investment is lower, the service life is longer, and the efficiency of energy conversion is more stable. As a result, the PSPS is currently the most mature and practical way for large-scale energy storage in the power system. The PSPS is the optimal tool for load regulation.
What are the two types of electricity price?
It has two kinds, including one-part electricity price, and two-part electricity price , . They coexist in the transition period of the power system reform. Most of the power plants adopt one-part electricity price, and others adopt two-part price.
