State Grid: Continue To Carry Out Research On Key Technologies For New Energy Storage Planning And Design To Contribute To The High-Quality Development Of New Energy Storage

Recently, the National Energy Board announced a list of 56 new energy storage pilot demonstration projects. State Grid Corporation's "Baiyangdian 8 MW /8 MWH lithium-ion battery energy storage demonstration project in Xiongan New Area, Hebei Province", "Shayang County, Hubei Province, 50 MW /100 MWH lithium-ion battery energy storage demonstration project", "Huainan City, Anhui Province, Shannan High-tech Zone water sodium-ion battery energy storage demonstration project" was successfully selected.

In recent years, the company has actively supported the large-scale development of new energy storage, continued to strengthen research on key technologies for new energy storage, built a State key laboratory for energy storage, actively promoted the establishment of a sound standard system for new energy storage technology, supported the development of new energy distribution storage and user-side storage, and actively served and participated in the construction of energy storage on the grid side. At the same time, the company has completed and put into operation a number of new energy storage demonstration projects according to local conditions, made a series of breakthroughs in key technologies such as grid type energy storage and seamless off-grid switching, explored the path for new energy storage to participate in market transactions, promoted the full role of new energy storage, and provided strong support for accelerating the construction of a new power system.

The three selected pilot projects have made breakthroughs in key technologies and operation models, and solved practical problems in power grid operation through new energy storage applications, and led to the upstream and downstream development of the industrial chain.

"Baiyangdian 8MW / 8MWh lithium-ion battery Energy Storage Demonstration Project in Xiongan New Area of Hebei Province" adopts the fast coordinated control algorithm of optical fiber synchronization and multi-host backup and grid type energy storage technology to realize the millisecond seamless switching, second-level system recovery and minute-level black start-up of the 35 kV system, and improves the power supply reliability of the core scenic spot of Baiyangdian through a more economical networking method. Promote local consumption of new energy.

The "50 MW /100 MWH lithium-ion battery Energy Storage Demonstration Project in Shayang County, Hubei Province" has overcome the technical problems of grid energy storage simulation technology and performance evaluation, completed a complete set of on-site tests of grid energy storage power station, and verified the effect of grid energy storage system in voltage and frequency independent support and user power quality improvement. Successfully promote the engineering application of grid type energy storage in China.

"Anhui Huainan City Shannan High-tech Zone water sodium-ion battery energy storage demonstration project" the country's first (set) megawatt-hour water ion energy storage device based on neutral salt hydrolytic solution, the project will complete the domestic independent intellectual property rights of water ion battery technology chain verification. The project construction will accelerate the development and application process of water-based sodium-ion batteries, and demonstrate the high-quality development of upstream and downstream enterprises and strategic emerging industries.

The company will promote the construction of new power systems with digital intelligence and strong power grids, do a good job in tracking and evaluating new energy storage pilots, continue to carry out research on key technologies for new energy storage planning and design, and contribute to promoting the high-quality development of new energy storage.
