Russian pumped 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 are the characteristics of pumped-storage power stations?

Through the characteristics analysis of the new type of pumped-storage power station, three types of optimal station locations are proposed, namely, the load concentration area, new energy concentration area, and ultra- high-voltage direct current receiver area.

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.

What is a fixed-speed pumped-storage power station?

The fixed-speed pumped-storage power station has a step-type output. Take one of pumped storage power stations as an example. It takes only about 16 s from −50 MW to −300 MW, and just 14 s from −300 MW to 0 MW. It means a 300 MW unit trips several times in one day, which has a great impact on the Fujian province power grid.

Can pumped-storage power station 239 improve the response speed?

The joint operation of the optical storage system Vol. 2 No. 3 Jun. 2019 Jingyan Li et al. Prospect of new pumped-storage power station 239 with sufficient capacity and the pumped-storage power station can improve the response speed of peak modulation, frequency modulation, and phase modulation of the power grid.

What are the operating states of conventional pumped-storage power stations?

There are three operating states of conventional pumped-storage power stations, namely, resting state, pumping state, and power generation state, as shown in Fig. 4.
