Recently, the 1 GW/4 GWh large-scale energy storage power station project in Dengkou reached a critical milestone. Through concerted efforts and rigorous testing by the project team, the commissioning unit, and relevant grid authorities, all core grid-connection tests were successfully completed. The four key test items—power quality, overload capacity, emergency power support, and active power control—all passed on the first attempt. All technical performance indicators fully comply with the grid connection and operation standards, laying a solid foundation for the project’s subsequent stable grid integration and efficient commissioning.
As a key energy storage demonstration project with large capacity and high proportion in the region, the Dengkou 1 million kW/4 million kWh energy storage project shoulders the important mission of optimizing the regional energy structure, improving the peak regulation capacity of the power grid, and ensuring the safe and stable operation of the power system. The grid-related test is the core link before the energy storage project is connected to the grid and put into production, which is directly related to the coordination of the project and the grid, operational safety and regulatory response efficiency. The four tests completed this time fully covered the core technical requirements of the project’s grid-connected operation, and fully verified the project’s equipment performance and system control capabilities. The successful completion of multiple grid-connection tests signifies that the Dengkou 1 GW/4 GWh energy storage project has fully met the technical requirements for grid integration and operation, marking a significant milestone in the project’s overall construction and commissioning efforts. Once commissioned, the project will fully leverage the advantages of a large-capacity energy storage power station in peak-shaving and valley-filling, emergency support, and power quality stabilization, thereby effectively enhancing the regional grid’s capacity to integrate renewable energy, improving grid security and risk prevention, and supporting the development of a new-type power system. It will provide robust assurance for the region’s green and low-carbon energy transition and reliable electricity supply.
