The result shows the urgency of developing the PSPS in Chinese power systems that have given priority to thermal power, and the energy resources need the wide-range optimal allocation within the system. The development cycle of the pumped storage is long, and at least 8–10 years are needed from the planning to the completion.
The PSPS is the best tool for energy storage. The pumped storage has the function of energy reserve, and it solves the problem of electricity production and consumption at the same time, and not easy to store. Thus, it can effectively regulate the dynamic balance of the power systems in electricity generation and utilization.
As to the hydro-generator, its load regulation speed can match the pumped storage unit. But only the hydropower station with the annual regulation performance and above has good load regulation capability. In China, this type of stations that can be developed are becoming less and less.
Hence, the independence of manufacturing pumped storage units can be gradually realized in China. If the equipments are capable to be made in China, they should be used as much as possible, which can actively improve the localization of the pumped storage units.
In fact, the main equipments of the pumped storage unit, including the pump turbine and motor generator, are basically the same with the conventional hydroelectric generating sets. They are only different in that the operation condition of the former is more complex, and the automatic control components account for a larger proportion.
