Development path and standardization of grid-forming active support technology

Abstract In recent years, the active support control technology has been preliminarily applied and verified in various grid-forming (GFM) converters such as GFM energy storage, GFM SVG, and GFM VSC-HVDC. At present, the characteristics and stability analysis of GFM active support technology have been summarized in the existing literature, but there is no systematic elaboration and analysis of the development path and technical standardization of this technology in the new power system. On the basis of combining the standardization of the technical equipment system and the technical index system of the GFM technology, the construction principle and architecture design of the GFM technology technical standard system are discussed, and the conceptual model and technical standard system of the GFM technology standard are given.
