6 FAQs about [Supply of energy storage variable frequency heating unit]

Can pumped storage stations be used as energy storage support?

With China continuously scaling up the construction of integrated clean energy bases like “hydro-wind-storage” and new energy bases such as “Shagohuang”, pumped storage stations, especially variable-speed ones, will be more widely applied as energy storage support in regional grids (China Power, 2023).

What is variable-speed pumped storage (VSPs) technology?

As the most advanced pumped storage technology internationally, variable-speed pumped storage (VSPS) technology is the inevitable direction for the development of pumped storage technology in China.

What is the share of pumped storage and gas-fired power plants?

As of the end of 2020, the share of pumped storage and gas-fired power plants in their power systems is shown in Table 4. From the table, it can be observed that the proportion of regulation power sources in these countries exceeds 10 %, with Italy exceeding 50 %. The lowest share of pumped storage power generation is 2 %.

How many pumped storage power stations were built in 2023?

In 2023, 239 pumped storage power station projects underwent updates, with a total capacity exceeding 316.735 GW and total investment exceeding trillions of yuan. The scale of pumped storage construction in each province is shown in Fig. 6. Fig. 6.

What is VSPs technology & units?

VSPS technology and units involve multiple disciplines such as electromagnetics, hydraulics, power electronics, and control systems. It is necessary to achieve top-level design and system research through close collaboration across disciplines, specialties, and between industry, academia, and research institutions.

What are the advantages of VSPs over fixed-speed pumped storage?

Firstly, VSPS technology has significant advantages over fixed-speed pumped storage in terms of grid-side, power station-side, and unit performance. VSPSUs can significantly improve hydraulic performance, power regulation capability, and system economic efficiency by adjusting the unit's rotational speed.
