The reporter learned from the State Grid Qinghai Electric Power Company of China that as of the end of February, Qinghai Power Grid had generated 101.
27 million kilowatt-hours of new energy through shared energy storage, marking the first time that China's shared energy storage has exceeded the 100 million mark
.

As one of the regions with the most abundant clean energy, Qinghai accounts for about 11% of China's solar energy resources, and its solar thermal resources ranks second in China
.

At the same time, Qinghai also has a large number of deserts, Gobi and deserts that can be used for new energy development

According to reports, as of the end of February this year, the grid-connected electrochemical energy storage capacity of Qinghai Power Grid was 363,000 kW/498,000 kWh, of which 2 were participating in shared energy storage, with a total capacity of 82,000 kW/164,000 kWh.

A total of 366 new energy power generation companies participated in shared energy storage transactions, with a total of 3,533 transactions, with a total charging capacity of 99.
03 million kWh and a total discharge capacity of 81.

According to reports, the characteristics of new energy power generation, such as poor adjustment flexibility, intermittency and strong volatility, bring huge challenges to new energy consumption and large-scale development
.

Energy storage plays an important role in peak shaving and valley filling of the power grid.
When there is excess new energy generation, the excess electricity is stored and released when electricity is in short supply

At present, the main scenarios of energy storage applications in China are the power supply side, the load side and the grid side.

However, the three application scenarios are generally independent, decentralized, and low in utilization.

In order to fully release the energy storage development potential of Qinghai Power Grid, in 2018, State Grid Qinghai Power actively carried out research on the application of shared energy storage, and proposed the concept of "shared energy storage" for the first time in China, integrating the energy storage resources of power sources, users and power grids.

, take the power grid as the central platform to optimize the configuration, while providing services for the power supply and users themselves, flexibly adjust the control mode to realize the sharing of energy storage resources across the entire network, so as to realize the full release of the energy storage capacity of all parties in the source, network, and load
