The technical standard system is one of the core elements of the foundation of energy and electric power industry. To promote the development of new power system construction standard and to meet the demand of power system construction, the overall framework of the technical standard system for the new power system is studied considering the development direction and actual demand. Considering the national and industrial requirements on the preparation of technical standard system, the key technical areas involved in the new power system are examined from a strategic perspective. Existing standards and related standard systems are analyzed and selected from the perspective of adaptability. A flexible and extensible conceptual model of the new power system technical standard system is presented, which includes four parts: basic generality, physical basis, information support and value enhancement. The architecture is constructed which consists of four hierarchies, 14 technical domains, 138 categories, and several specific standards. On this basis, the future requirements of the standard system in all fields are analyzed, and the future standard layout planning suggestions are put forward.
