Abstract: The metaverse is a collective virtual shared space constructed using various technologies, which can perform ultra-low cost trial and error verification on power systems and assist personnel and organizations in immersive communication beyond time and space. It can serve as a "test station" in the development path of new power systems. This article is based on the concept of a cyber-physical-social system and designs the early, middle, and later application scenarios of the power dispatch metaverse. The dispatcher training simulation scenario is selected as the initial verification scenario. A prototype system of the power dispatch metaverse has been designed and developed, and it includes a light three-dimensional engine for power dispatch, a virtual dispatch hall, a digital clone, and a virtual grid. It is piloted in provincial power grids to improve the operation and control technology of power system dispatch, providing a paradigm for the promotion and application of the power dispatch metaverse in other scenarios in the future.
