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.

How can pumped-storage systems improve power-compensation response speed?

The new-generation pumped-storage station can automatically track power-grid frequency change and quickly regulate active power. Electrochemical energy storage can improve power-compensation response speed. Variable-speed pumped-storage units can achieve real-time automatic frequency tracking.

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 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 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.

What is the regulation rate of Beijing Shisanling pumped storage power plant?

The regulation rate of Beijing Shisanling Pumped Storage Power Plant with automatic generation control (AGC) is approximately 100 MW/min. For the start-up time, the variable-speed unit needs ~2.5 min, and the fixed-speed unit needs ~5 min [7-8].
