6 FAQs about [Preliminary design requirements for energy storage power stations]

What is the rated power of a cascade hydropower station?

Moreover, the rated power of the pumping station is set at 1000 MW. All the planned capacity of wind and solar power in the HWSCEB are assumed to be commissioned. Fig. 6. Basic overview of the cascade hydropower stations. Table 1. Basic characteristics of the cascade hydropower stations.

What is the efficiency of a pumping station?

For simplicity, the pumping station overall efficiency ( η o v e r a l l) is considered constant [ 13, 32, 35 ], and equal to 0.80. Moreover, the rated power of the pumping station is set at 1000 MW. All the planned capacity of wind and solar power in the HWSCEB are assumed to be commissioned. Fig. 6.

Can a pumping station provide energy storage for Cascade hydropower stations?

Energy storage of cascade hydropower stations achieved via a pumping station. Feasibility of the large-scale cascade hydropower energy storage system is evaluated. Excess electricity can be effectively utilized to recover water potential energy. Pumping station efficiency is critical to the economic feasibility.

Can commissioned new energy power plants be used as a reference value?

If there are commissioned new energy power plants in the HWSCEB, the theoretical output of new energy power plants with ultimate planned capacity can be approximately computed with the historical actual output of commissioned new energy power plants as reference value, like the literature [ 29 ].

Should water supply reservoirs be used for power generation?

However, the primary goal of the existing water supply reservoirs is not the power generation, which will raise two main concerns: (1) the dams of water supply reservoirs may not have the potential to support endeavors associated with energy storage; (2) the construction of new power transmission infrastructures will increase investment costs.

How is a conventional hydropower station transformed to a pumped hydro storage?

In literature [ 20, 21 ], a conventional hydropower station was transformed to a pumped hydro storage by installing a pumping system; the reservoir of the hydropower station and its downstream non-hydropower reservoir were used as upper and lower reservoirs respectively.
