Research on Optimization of Flexible HVDC Transmission Standards System
With the advantages of low loss,small harmonic and easy expansion,the flexible DC transmission technology with modular multilevel converter as the core has become a new transmission technology to enhance the stability and flexibility of new energy grid connection and support energy transformation.With the gradual increase of engineering application of flexible transmission technology in recent years,it is necessary to improve the flexible DC transmission standards system to meet the needs of flexible DC transmission technology development and subsequent promotion and application.This paper combs and constructs the existing national and industrial standards system of flexible DC transmission,proposes the optimization development direction in combination with the new technologies and equipment emerging in the field of flexible DC transmission in recent years,defines the standards and needs to be revised and supplemented,and provides reference for standardizing the development of relevant technologies in the field of flexible DC transmission,guiding the development of standards,improving the standards system,and promoting the internationalization of advanced standards.
