With the successful integration of the first batch of wind turbines into the grid, China's largest grid type wind power project, the Huaneng Shangyi Wind Storage Active Support New Smart Power System Demonstration Project, has been officially put into operation. This is not only a 500000 kilowatt wind power base, but also marks a crucial step for China's new energy power system to move from "passive follow-up" to "active construction" of the grid due to the mass application of Goldwind Technology's innovative DC coupled grid wind storage integrated machines, providing a new solution for the integration of high proportion renewable energy into the grid.

The largest grid connected wind power base in China

The project is located in Shangyi County, Hebei Province, and is one of the third batch of large-scale wind and photovoltaic base key projects in China, with a planned total capacity of 500000 kilowatts. The successful grid connection of the first batch of wind turbines marks the entry of the project into the actual power generation stage. The project innovatively adopts the "one machine, one storage" deep integration mode, and is equipped with Goldwind Technology's GWH204-6.25MW DC coupled grid wind storage integrated machine with a total capacity of 150 megawatts, with a supporting energy storage system scale of 100MW/200MWh. This configuration aims to significantly enhance the active support capability of the station to the power grid, transforming it from a traditional power "supplier" to a "participant" and "supporter" in the stable operation of the power grid, providing an important engineering demonstration for building a new type of power system.

Solving the problem of weak current network with grid type wind turbines

The power grid environment where the project is located is weak, with a minimum short-circuit ratio of only 1.4, belonging to a typical weak power grid area. Traditional wind turbines are prone to power rationing and disconnection risks in such environments. The Goldwind Technology grid type wind storage integrated machine applied in bulk this time has mature "isolated network operation" and "black start" capabilities, and can adapt to extreme weak current network environments with a minimum short-circuit ratio of 1.2. The core of its technology lies in achieving real-time voltage stabilization and grid stability through energy storage systems, enabling wind turbines to transform from "passively following grid frequency and voltage" to "actively building and maintaining grid stability", effectively resisting grid disturbances, and greatly improving grid reliability and power generation utilization under weak grid conditions. This technological equipment has been selected as the first (set) major technological equipment in the energy field by the National Energy Administration in January 2025.

Leading the transformation and upgrading of the new power system

The successful grid connection and operation of the Shangyi project have multiple strategic significance. Firstly, it verifies the feasibility and effectiveness of the application of grid construction technology in large-scale new energy bases, providing a benchmark for the construction of similar projects in the future. Secondly, it converts unstable wind power into grid friendly stable power sources through technological means, which helps to solve the system stability challenges brought by the high proportion of new energy access and reduce the risk of large-scale grid disconnection. As a pioneer in this technology in China, Goldwind Technology has completed the full chain practice from single machine verification to on-site demonstration, and has begun to promote it globally. In the long run, the popularization of grid building technology will promote the transformation of new energy from supplementary energy to main supporting energy, accelerate the construction of new power systems, and ensure national energy security and green transformation.Editor/Gao Xue
