As the penetration rate of new energy generation rapidly increases

grid-forming energy storage converters

serving as core equipment for the stable operation of new power systems

face a critical bottleneck in their large-scale application: the uniformity and scientificity of grid-connected testing technical standards. This paper focuses on the grid-connected testing technical standards for grid-forming energy storage converters. It systematically conducts a comparative analysis of the technical specifications in the United States

Europe

and China from four dimensions: the development history of the standards

the testing indicators for power grid support functions

the requirements for single unit performance testing

and the testing method system. Based on the differences between domestic and international standards

this study expounds the quantitative functional indicators and testing specification requirements under the two respective system

and conducts an in-depth analysis of the technical implementation paths and verification methods for typical test scenarios. By comparing the characteristics of different standards in terms of the refinement level of testing indicators

the applicability of testing methods

and the engineering implementation paths

and combining with the requirements for constructing new power systems

this paper presents a vision for the international collaboration

multi-scenario adaptation

and integration of cutting-edge technologies in testing technical standards for grid-forming converters. The findings provide references for relevant technical research and engineering practices.
