Should Chinese power systems develop pumped storage systems?

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.

Why do we need pumped storage power stations?

The operation of pumped storage units improves the penetration rate of renewable energy , gives play to the advantages of complementary units, and improves the economic feasibility of the power grid system . Pumped storage power stations in different regions have different development modes.

What is the price mechanism of pumped storage power stations?

In terms of the pumped storage price mechanism, most of the existing studies focus on the price mechanism of pumped storage power stations at a certain stage, including the current two-part price mechanism and the bidding mechanism under the market environment, and the horizontal comparison of the multi-stage price mechanism is lacking.

PSH functions as a utility-scale method of energy storage, like a battery, by moving water between two reservoirs at different elevations. Water is pumped into the higher reservoir using energy from the grid during conditions of abundant energy supply, when prices are low.
