| Summary: | Information integration is an important part of the digital grid architecture. The purpose is to solve the information interaction obstacles between heterogeneous systems on the basis of making full use of the old system. This paper analyzes the development stage of digital power grid information integration from the perspective of information integration, and points out that the information integration of current digital power grid is mainly data-oriented integration. Based on the characteristics of digital power grid information integration, this paper puts forward a digital power grid information Integration solution combining horizontal information integration and vertical information integration, designs the overall architecture of digital power grid information integration, and elaborates the horizontal integration and vertical integration respectively.
