Can pumped storage power stations support a high-quality power supply?

Hence, to support the high-quality power supply, this research explores the complementary characteristics of the clean energy base building different types of pumped storage power stations, and recognizes the efficient operation intervals of the giant cascade reservoir.

How pumped storage power stations can improve Ur and LR?

The construction of pumped storage power stations among cascade reservoirs can improve the flexible adjustment ability of the clean energy base, which also changes the water transfer and electrical connection of UR and LR at the same time.

What is pumped storage hydropower (PSH)?

Pumped Storage Hydropower (PSH) is emerging as a key solution to address the challenges of volatility, intermittency, and randomness in large-scale variable renewable energy (VRE) like wind and solar power [3, 4], essential for grid stability and energy integration [4, 5].

Can PSH provide long-duration energy storage and water management services?

PSH could also provide long-duration energy storage and water management services such as water storage and flood control. However, there are still challenges to its deployment and operation related to power regulation quality, economics and environmental impacts.

What are the potential services and impacts of pumped storage hydropower?

These potential services and impacts are discussed in this section. Fig. 4: Economic and environmental factors and impacts. Pumped storage hydropower provides energy storage for power systems, ancillary grid services and water management, but also has economic and environmental impacts. GHG, greenhouse gas; VRE, variable renewable energy.

Can pumped storage power stations be built among Cascade reservoirs?

The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation.
