Research on Technical Standard System of New Distribution System Under Double-Carbon Strategy

In the context of “carbon peaking and carbon neutrality”, the construction of a new type of clean and low-carbon power system with high penetration of renewable energies is moving forward at a fast pace, which has profoundly changed the behavior and functional roles of power distribution system. However, the current standard system is hardly capable of meeting the requirements of the development of distribution network due to the absence of corresponding critical supportive standard in addition to its lack of compatibility, coordination and integrity in the entire power distribution business. By taking the technical development and business needs into full consideration, this paper puts forward the principles of systematic, coordinated, dynamic and prospective standard system construction. Based on the theory of multidimensional model, the snowflake multidimensional structure model is established, which lays the foundation for the information management of standard system. With the power distribution as the main technical direction, a multi-level standard architecture covering the whole life cycle is also designed. Finally with regards to the key technical fields, this paper analyzes the requirements for standards and implements the planning and layout of key standards, so as to provide effective standards and direction guidance for the promotion of the green and low-carbon transformation of smart distribution network.
