Huadian Tibet Project Achieves Stable Grid-Forming at Record 5,370m Altitude

A significant milestone in renewable energy integration has been reached with the successful connection of the Huadian Tibet Qiongjie 60MW wind farm to the grid. Situated at an altitude of 5,370 meters, this stands as the world's highest-altitude wind-storage grid-forming project. Equipped with Sungrow’s 12MW/48MWh PowerTitan energy storage system, the facility has demonstrated all-weather stability despite the extreme altitude and weak grid conditions, ensuring high wind power absorption and reliable transmission.

Compared to standard solar-storage systems, wind-storage integration faces greater challenges, including higher oscillation frequencies and lower inertia. At an ultra-high altitude of 5,370 meters, extreme diurnal temperature variations complicate turbine control, while the weak grid structure and low short-circuit capacity make stable power export difficult. Sungrow’s solution provides critical support, enabling the system to maintain stable grid-forming capabilities around the clock.

Integrated AC-DC Design Ensures Stability

Given the strong fluctuations in wind power output, synergy between equipment is vital. The PowerTitan system utilizes a full-stack, in-house developed AC/DC integrated design. This approach eliminates compatibility issues between components, ensuring efficient response and significantly enhanced system stability.

On the DC side, the system supports multi-port DC coupling and utilizes precise battery State of Charge (SOC) management. This ensures sufficient energy supply for grid-forming functions and accurate response to dispatch demands. Additionally, liquid-cooled AI thermal management allows the system to handle frequent charging cycles and intermittent overloads, effectively lowering operational losses.

On the AC side, the system relies on wide-range disturbance control technology. Through multi-dimensional self-synchronization algorithms, it actively constructs grid voltage and frequency, detecting and eliminating oscillations across the 0.1Hz to 2.4kHz range. This grid-forming capability increases the system's short-circuit capacity and resilience to shocks, allowing the grid to accommodate and export higher volumes of wind power.

With the Huadian Qiongjie project now operational, it is expected to generate enough clean energy to power approximately 120,000 households annually. The project validates the efficacy of grid-forming energy storage technology in extreme environments above 5,000 meters, setting a new global benchmark for wind-storage developments in high-altitude, weak-grid regions.
