Technology comment
A pumped-storage hydropower station is a hydropower station that uses electricity from the power grid during low load periods to pump water from the lower reservoir to the upper reservoir to store energy. When the power grid reaches peak load, the water is released back to the lower reservoir to generate electricity. The main difference from the modeling of storage dam-type hydropower stations is the number of reservoirs. The installed capacity of large-scale pumped storage power stations is ≥300 MW. Hydropower station parameters are set according to design specifications and standards, that is, the technical service life of small hydropower station projects is 30 years, the technical service life of medium-sized hydropower station projects is 50 years, and the technical service life of large hydropower station projects is 100 years.
