Abkhazia Pumped Storage Photovoltaic Power Station

What is a hydropower-wind-photovoltaic pumping station?

Compared with conventional hydropower-wind-photovoltaic (CHP-wind-PV for short hereafter) system, the pumping station can use the excess electricity from hydropower, wind power and PV plants or purchased from the power grid to pump water from the lower reservoir to the upper reservoir, thus achieving energy storage and efficient energy utilization.

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.

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.

Why do we need pumped storage power stations?

Hence, construction of pumped storage power stations can effectively improve the flexibility of the clean energy base and support the depth of new energy consumption .

Are pumping stations better than hwpbs?

Compared to batteries, pumping stations exhibit superior capability in absorbing excess curtailed power, resulting in an average annual return of LCHES over the entire project cycle that is 2.58 times higher than that of HWPBS. This is attributed to the long-time storage capability and larger storage capacity inherent in hydropower storage.

Can a PSH plant be used in a microgrid solar-wind system?

Ma et al. demonstrated that the introduction of a PSH plant into a standalone microgrid solar-wind system provided a reliable and environmentally friendly power supply on a remote island. Sun et al. proposed an operation scheme for PSH-wind-PV systems and proved that PSH could increase system power generation and reduce profit losses.
