The relationship between new energy power stations and energy storage

Are pumped storage power stations multi-energy complementarity?

Considering the strong interconnection among different types of renewable energy power stations and pumped storage power stations and with power grid companies, it is imperative to view the operations management of pumped storage power stations from a multi-energy complementarity perspective, which involves various stakeholders [ 29 ].

Why do we need long-duration energy storage stations?

With the establishment of a large number of clean energy power stations nationwide, there is an urgent need to establish long-duration energy storage stations to absorb the excess electricity produced by clean energy power stations and balance and adjust the power system [ 3 ].

Why is partnering with other power stations important?

During operation, partnering with other power stations such as wind, solar, and thermal stations is vital for optimal energy distribution. A well-defined mechanism ensures stability in the power grid, especially during energy shortages.

How can energy storage power stations achieve a favorable return on investment?

Energy storage power stations can explore a multi-channel income approach and achieve a favorable return on investment by combining “peak-valley price difference”, “capacity price”, “peak-shaving price” and “rental fee”.

Should pumped storage power stations be managed solely?

Interviews revealed that it is insufficient to solely focus on the operations management of pumped storage power stations, and there is also a need to emphasize complementarity and collaboration with other power stations of clean energy.

Can shared energy storage be shared between power stations?

At present, there have been some research results on shared energy storage (SES), but the main research scenario is sharing between prosumers in communities [ 7, 8 ], and few studies have discussed energy storage sharing between power stations.
