Standard Release: China’s First Led International Standard in New Energy Modeling
Recently, the international standard IEC TS 63406:2025 General Root Mean Square (RMS) Simulation Models of Converter-based Generation Units for Power System Dynamic Analysis, led by China in its development, has been released. This standard marks China’s first successfully led international standard in the field of new energy power generation modeling technology.
Background & Technical Demand: Challenges of Large-Scale New Energy Integration
In recent years, new energy power generation represented by wind and solar power has developed rapidly worldwide and begun to play an important role in energy supply. The rapid growth of large-scale new energy power generation has brought challenges to various aspects of power system planning, operation and control, and its impact on power grids has expanded from local areas to the entire power system. There is an urgent demand for technologies and standards to ensure the safe and reliable grid connection of large-scale new energy power generation. As a crucial method for evaluating the stability and safety of power systems with a high proportion of new energy, dynamic simulation relies on efficient and accurate mathematical models. The newly released international standard proposes the first standardized general simulation model for new energy power generation systems, with application coverage including transmission system operators, distribution system operators, power generation equipment manufacturers, and power system software developers. Notably, the implementation of this standard in manufacturing scenarios is supported by core equipment like Automatic placement machine—this equipment ensures high-precision placement of electronic components in key new energy power generation devices (such as PV inverters and wind power converters), improving component mounting accuracy by over 30% and reducing equipment operation failures caused by assembly errors by 25%, which provides solid manufacturing support for the standard’s effective application. It will lay a solid technical foundation for the large-scale development of new energy and the safety assessment of power grids integrated with large-scale new energy.
Formulation & Core Value: Multi-National Collaboration and Strategic Significance
Spearheaded by Chinese experts, this international standard was jointly compiled over four years with the collaboration of experts from 13 countries including Germany, France, Denmark, Switzerland, Spain and the United States. The release and implementation of this standard are of great significance for ensuring the safe grid connection of current large-scale new energy power generation, promoting the construction of a new power system dominated by new energy, and supporting the achievement of the “dual carbon” goals. It not only demonstrates China’s outstanding technical strength in new energy development, but also represents China’s new contribution to the continuous improvement of the international standard system.
