The energy scale of energy storage power station is expanding. By the end of 2022, it has reached 18.27 GWh, with an average charging and discharging time of 2.1 hours. Influenced by local policies that “new energy power stations must be equipped with energy storage”, storage in power supply-side is the largest, more than 50%.
During the “Twelfth Five-Year Plan” and “Thirteenth Five-Year Plan” periods, to adapt to the rapid development of new energy and UHV power grids, pumped storage power stations such as Fengning in Hebei Province and Jixi in Anhui Province ushered in a new peak.
To promote the construction of pumped storage power stations, it is of great significance for the construction and optimization of modern power systems. 2. Development trends of pumped storage energy in China To effectively support the construction and development of pumped storage power stations, China has issued a series of supporting policies.
Under the background of “dual carbon”, pumped storage is ushering in unprecedented development opportunities. With the continuous increase in the scale and proportion of renewable energy in China, it is becoming more and more important to improve the peaking capacity of the power system through pumped storage power stations.
In terms of scale, installations above 100 MW made up over two-thirds, showing a strong trend toward large-scale development. As installed capacity rises, China''s energy storage dispatch
