Puji pharmaceutical energy storage power station

What is pumped-storage power station?

The pumped- storage power station can achieve long-term storage of large-capacity power by itself. The multiple-energy- combined pumped-storage station can also improve the quantity of new energy connecting to the power grid on the premise of guaranteeing the stability and safety of the Global Energy Interconnection 240 power grid.

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.

What are the advantages of pumped storage-power stations?

The power response speed of the new pumped- storage station can reach the millisecond level, which greatly enhances the safety, reliability, and comprehensive adjustment capability of original large-scale pumped storage-power stations. Both sunlight and water resources are green and clean energy.

How much power does Okawachi pumped storage power station have?

The 400- MW variable-speed unit of the Okawachi Pumped Storage Power Station in Japan can change 32 MW output power or 80 MW input power within 0.2 s . The regulation rate of Beijing Shisanling Pumped Storage Power Plant with automatic generation control (AGC) is approximately 100 MW/min.

Can variable-speed pumped-storage technology improve the operational flexibility of traditional power stations?

The operational flexible of the traditional pumped-storage power station can be improved with variable-speed pumped-storage technology. Combined with chemical energy storage, the failure to achieve second-order response speed and the insufficient safety and reliability of pumped-storage power units could be solved.

What is Ningxia power's energy storage station?

On March 31, the second phase of the 100 MW/200 MWh energy storage station, a supporting project of the Ningxia Power’s East NingxiaComposite Photovoltaic Base Project under CHN Energy, was successfully connected to the grid. This marks the completion and operation of the largest grid-forming energy storage station in China.
