The construction of large ultra-high voltage AC/DC hybrid power grid in China has greatly improved the ability to optimize the large-scale allocation of resources, but it also poses new challenges to the power grid dispatch and control system. This paper analyzes the development situation and characteristic variety of power grids, and new demands for power grid dispatch and control technology support. On this basis, the architecture of a dispatch and control system with the characteristics of physical distribution and logical integration is put forward. Also, the core technologies of basic support, model cloud, big data, dispatch and control based on source-grid-load interaction, integrated security risk prevention and control of large power grid, test verification, and system operation & maintenance, are analyzed in detail.
