Pumped-storage hydroelectricity

Pumped storage is the use of water as a medium to store and manage electrical energy through the conversion of electrical energy and potential energy. By utilizing the electricity generated during low load periods to pump water to the upper reservoir, and then releasing water to the lower reservoir for power generation during peak load periods, the excess electricity generated during low load periods of the power grid can be effectively converted into high-value electricity during high load periods.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The energy revolution has driven a surge in demand for pumped storage energy. With the large-scale and rapid development of renewable energy sources such as wind and solar power worldwide, the volatility and intermittency of the power system have become increasingly prominent, and the demand for regulating power sources has significantly increased. Pumped storage is a green, low-carbon, clean, and flexible power source with mature technology, superior economic efficiency, and large-scale development conditions for power systems. It works well in conjunction with wind power, solar power generation, and other sources. The development of pumped storage is an important support for ensuring the safe and stable operation of the power system, and an important guarantee for the large-scale development of renewable energy.
