Main technical content: This standard provides an evaluation model for digital grids in super-large cities. The evaluation grade classifies digital grids in super-large cities into four levels from low to high: initial level, basic level, optimization level, and leading level. The evaluation indicators highlight the main aspects of digital grid evaluation in super-large cities, which are collected, organized, and refined from nearly 133 relevant documents at the national level, power grid companies, and Shenzhen Power Supply Bureau. Subsequently, some innovative indicators are also proposed and refined after soliciting opinions from relevant departments and experts. In accordance with the requirements of being evidence-based, highly representative, comparable, and data-accessible, the standard covers five first-level evaluation indicators and their corresponding 15 second-level and 44 third-level evaluation indicators in the areas of smart production and operation, agile urban empowerment, digitalization of all-domain equipment, three-dimensional safety prevention and control, and collaborative ecological co-creation. Based on the above model, the standard proposes that the evaluation of digital grids in super-large cities be conducted by combining key indicator evaluation and comprehensive scoring (D), and provides specific evaluation elements such as indicator calculation methods, compliance values, thresholds, and weights. Among them, the determination of the maximum and minimum thresholds for classification indicators is based on multiple considerations to ensure the scientificity and practicality of the indicators. Firstly, referring to relevant national standards and industry norms, the reasonable range of indicators is determined. Secondly, combining with the actual operation of digital grids in super-large cities, the extreme value distribution of different indicators is analyzed, and the urban development planning and future power load growth trends are tak
