On August 17, the innovative demonstration project of compressed air + lithium battery combined network side shared energy storage power station in Tongwei county, Dingxi city, which was contracted by EPC of Shanghai complete Institute of State Power Investment Corporation, successfully completed the hoisting of turbine generator set and the installation of the first gas storage Pipeline steel, it indicates that the project has successfully entered the key research stage of main equipment installation.

Since the project started in July 2023, with the strong support of the leaders of Shanghai complete sets of colleges and project owners, the relevant work of the project department has been steadily promoted. The turbine power generation system of the project creatively adopted the high-efficiency operation technology with large sliding pressure and wide load. The in-plant type test of the turbine generator set passed smoothly at one time and completed the on-site hoisting. The gas storage device creatively adopts large pressure drop gas storage technology and multi-layer series-parallel module design, which has significant advantages such as high energy storage density, good economy and flexible operation. As the EPC general contractor, our hospital takes the lead in solving the technical difficulties of pipeline steel system installation, organizes multiple rounds of technical discussions and industry experts to demonstrate, and formulates the special technical scheme of gas storage device hoisting, innovatively put forward the construction technology of "three-machine balance beam lifting" of overhead super-long pipeline steel to realize the safe and stable hoisting of the project's gas storage Pipeline steel and ensure the efficient advancement of the project.

This project is the first in China compressed air + lithium battery pack the combined shared energy storage power station, which provides comprehensive power auxiliary services, has been listed as the key supporting construction project of the National Energy Administration in 2023 for rural revitalization. The project adopts the combined compressed air energy storage technology with independent intellectual property rights developed by the Shanghai complete Institute of China Electric Power Investment Corporation, and the technology has been successfully selected into the catalogue of energy saving and carbon reduction technology equipment recommend of the Ministry of Industry and Information Technology. Next, the project team of Shanghai complete set Institute will work closely with all parties to the project, give full play to its professional advantages, steadily promote the installation and commissioning of main equipment, and play a leading role in demonstration project technology, contribute to the full implementation of the "balanced growth strategy" by the national electricity investment.
