Abstract

Abstract:

The Xinjiang power grid is dominated by a high proportion of renewable energy and exhibits the typical west-to-east power transmission. It faces the dual challenges of long-distance power transmisson and weak-infeed operation. Grid-forming energy storage technology, with its voltage-source characteristics, has become a core supporting technology for addressing Xinjiang’s renewable energy accommodation challenges and ensuring grid security, and it has undergone demonstration validation in the region. Starting from the actual requirements of the power system, the technical features of grid-forming energy storage are described. Using typical application scenarios and demonstration projects in the Xinjiang power grid, it explains the functions that grid-forming energy storage will perform in future power systems. The technical indicators and existing issues related to the grid connection of grid-forming energy storage projects are discussed, and development suggestions are provided, offering practical references for the advancement of this technology.

Key words: grid-forming technology, grid-forming energy storage, Xinjiang power grid, long-distance power transmisson
