The 2026 Grid-Forming Technology and Equipment Innovation Development Conference held in Zhangjiakou marked a pivotal moment for the wind energy industry as the technology transitioned from demonstration projects to commercial-scale deployment. Industry leaders, researchers, and equipment manufacturers gathered to discuss how grid-forming control strategies are becoming essential for maintaining power system stability as renewable energy penetration reaches unprecedented levels.

The fundamental challenge driving grid-forming technology adoption stems from the displacement of synchronous generators by inverter-based renewable resources. Traditional wind turbines operating in grid-following mode rely on the voltage and frequency reference provided by the main power grid. As synchronous machines are retired and replaced by power electronics-interfaced generators, system inertia decreases and short-circuit ratios decline, creating conditions where grid-following controllers become unstable.

Grid-forming control addresses this challenge by enabling wind turbines and energy storage systems to establish their own voltage and frequency references, effectively providing the stabilizing functions previously delivered by rotating machines. This capability becomes critical in weak grid conditions, islanded systems, and networks with high renewable penetration where traditional stability mechanisms are insufficient.

Policy support for grid-forming technology has strengthened considerably. China's 15th Five-Year Plan explicitly calls for increased application of grid-forming technologies, building on earlier directives from the National Energy Administration that identified these capabilities as essential for integrating renewable energy in weak grid areas and desert renewable energy bases. The policy framework creates a clear market signal for equipment manufacturers and project developers.

Engineering experience with grid-forming systems has expanded significantly. Shanghai Electric Wind Power Group reported deep application of grid-forming control technology, demonstrating良好 peak-shaving capability and enhanced grid compatibility. The company has developed monitoring and lifetime prediction technologies based on physical models, enabling operators to maximize energy production while maintaining equipment integrity under varying grid conditions.

State Power Investment Corporation's Yunnan International subsidiary achieved a significant milestone by commissioning the first high-altitude grid-forming wind turbine at the Fuyuan West Phase IV wind farm. Operating at elevation where air density is lower and turbulence patterns differ from coastal sites, the turbine demonstrates that grid-forming capabilities can be adapted to challenging environmental conditions. The system was developed through collaboration with the corporation's central research institute, Hunan University, and Goldwind Technology.

The technical challenges of implementing grid-forming control in wind turbines are substantial. Controllers must manage the interaction between aerodynamic power capture, mechanical drivetrain dynamics, and electrical power conversion while maintaining stable voltage and frequency outputs. The control algorithms must respond rapidly to grid disturbances while respecting physical constraints on turbine loading and energy storage state of charge.

Hybrid wind farms combining grid-forming and grid-following turbines present additional complexity. Coordinating the behavior of different turbine types requires sophisticated communication systems and hierarchical control architectures. Researchers are developing protocols that enable grid-forming units to provide stability support while grid-following units maximize energy production, optimizing overall farm performance.

The conference also addressed the economic dimensions of grid-forming technology. While the additional control capabilities require more sophisticated power electronics and software systems, the value proposition extends beyond individual turbine performance. Grid-forming wind farms can provide ancillary services including voltage regulation, frequency response, and black-start capability, creating additional revenue streams that improve project economics.

Standardization remains an ongoing challenge. Unlike grid-following systems where decades of operational experience have established clear performance expectations, grid-forming technology is still evolving. Industry participants at the conference emphasized the need for standardized testing protocols, performance metrics, and certification procedures that enable fair comparison between different approaches and build confidence among system operators and investors.

Looking ahead, the integration of energy storage systems with grid-forming wind turbines offers additional flexibility. Batteries can provide the fast-acting power injection or absorption needed to maintain voltage and frequency stability during transient events, complementing the slower response of turbine aerodynamic controls. This combination positions wind-plus-storage projects as grid-stabilizing assets rather than variable generation sources.

The technical requirements for grid-forming capability are substantial. Wind turbines must be equipped with advanced power electronics, sophisticated control algorithms, and energy storage systems that can respond rapidly to grid disturbances. These requirements add complexity and cost to wind turbine designs, but the benefits in terms of grid stability and renewable energy integration are considered essential for the energy transition.

Grid operators are increasingly recognizing the value of grid-forming capabilities in maintaining system reliability. As synchronous generators are retired and replaced by inverter-based resources, the traditional sources of grid stability are diminishing. Grid-forming wind turbines and energy storage systems can help fill this gap, providing the inertia and frequency response needed to maintain stable grid operation.

The development of grid-forming technology also has implications for wind turbine design and control strategies. Manufacturers must optimize the interaction between aerodynamic control, power electronics, and energy storage to achieve the desired grid support functions while maintaining efficient energy production.
