The Transmission Technology Maturity Assessment and its Effect on the Asia Power Grids Interconnection Development Patterns

This paper mainly focuses on the future transmission technologies trend, such as regular long-distance transmission technology UHV AC and DC technology, flexible HVDC, DC grid, high $-T_{-}c$ superconductors DC, half wave-length AC transmission, Gas Insulated Line technology. The technology maturity assessment method is applied to evaluate the development of transmission technologies at different stage. Based on the analysis on future development trend of electric power transmission technology, three Asia power grids interconnection modes are proposed, which are UHV AC synchronous power grid, HVDC power supply and DC power grid. The relationship between transmission technology maturity and power grid structures is researched. According to the transmission technologies maturity assessment results, the future Asia power grid patterns are proposed in 2020, 2030 and 2050. Finally, the evolution law of future power grid is clarified by the correlation of key transmission technologies maturity value and power grid development situation.
