Pumped-storage power (PSP) station operation, known for its critical role in power grid system management, including load peak-shaving, load valley filling, frequency modulation, phase modulation, and emergency backup, holds great importance, , .
In general, units cannot operate in the phase modulation for a long time under pump storage status. Rotating backup for power generation cannot be substituted by unit idling or phase modulation in power generation. Unit statuses cannot be switched between power generation and pump storage.
1742-6596/2083/2/022054 Abstract The pumped storage power station realizes grid connected power generation through the conversion between the potential energy of surface water and mechanical energy. It has become the strategic resource of UHV power grid with its low valley peak regulation and emergency standby function.
