6 FAQs about [Treatment of employees in pumped storage power stations]
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.
Why is pumped Energy Storage important?
Besides, it is an effective power storing tool and now it has become the largest and most widely used energy storage form. Many countries configured a certain proportion of pumped storage power in the network to keep their grid stability.
Does pumped storage power maintain grid stability?
Many countries configured a certain proportion of pumped storage power in the network to keep their grid stability. This paper introduces the current development status of the pumped storage power (PSP) station in some different countries based on their own economic demands and network characteristics.
What is pumped-storage & how does it work?
Pumped-storage can quickly and flexibly respond to adjust the grid fluctuation and keep the grid stability because of its various functions. Besides, it is an effective power storing tool and now it has become the largest and most widely used energy storage form.
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 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.
